Title: SymbioCity CleanWater Offer
1SymbioCity CleanWater Offer
A Swedish Integrated Water and Wastewater
Business Initiative
2The Swedish Model
... for integrated water and waste water
management
- In Sweden the private and public water sector has
worked with the device that high standards for
water supply and sewage is the basis for high
living standards. To reach those objectives it is
necessary to consider the overall water
situation, which is the foundation of the Swedish
model. - The Swedish model means putting all of the pieces
together. Social, environmental and technical
aspects. To ensure sustainable water usage,
reliable water supplies, better water quality,
environmental stewardship, efficient urban
development, protection of agriculture, and a
strong economy. - In more detail this means an integrated view
regarding waste water treatment, drinking water
supply, rain water treatment, sanitation and
energy production. The model has, regardless of
project size (e.g. single plants or entire
regions), rendered in optimised usage of water,
raw materials and energy both in short and long
term. - The key driver of the Swedish Model is the close
collaboration between Swedish private and public
water sector, academia, financing and
governmental bodies, which has resulted in a
world leading water and waste water management.

15Drinking Water Supply
Benefits Safeguarding public health Sustainable
production systems
- Rationale
- Nothing has greater impact on our lives than
water. Water is fundamental for our health,
comfort and prosperity. We believed water to be
an endless resource, and Nature would take care
of any irresponsible misuse. Today, we know
better! CleanWater has the knowledge and
experience to handle any aspect of fresh water
production, from an sustainable point of view. - History
- Swedish members of the CleanWater have worked
within this area for over 140 years! Export
started 1903! In the early days focus was on
providing freshwater and fire fighting. Today the
focus are from a broader perspective including
environmental, social and economical effects,
reaching from a whole region to a single plant.

16Wastewater Services and Systems
Benefits Sanitation Decreased eutrophication
- Rationale
- Adequate wastewater treatment is fundamental in
order to avoid sanitary and health problems in
populated areas. It also serves as a measure for
environmental protection, thus preventing
contamination and eutrophication of receiving
waters. Another aspect of wastewater treatment is
the potential for nutrient recovery re-cycling
of nutrients for fertilisation of cultivated
land. - History
- Thanks to its long history of municipal
wastewater treatment, today Sweden has one of the
most far-reaching effluent standards in the world
for treated wastewater. Sewage treatment plants
were introduced as early as the 1930s.
Mechanical treatment was followed by biological
treatment in the 1950s and chemical treatment by
means of precipitation in the 1970s, thereby
reducing discharges of the nutrient phosphorus.
During the final decade of the century, nitrogen
reduction was introduced for all major coastal
plants. - Projects
- The several thousand reference projects covers
all the aspects within this business area, from
the idea stage through feasibility,
planning/designing, construction, management and
monitoring of new or existing water or waste
water plants in conjunction with energy
production facilities, to turn-key and functional
sales contracts. Demonstrations and educational
services can be provide around the globe as well

17Bio Gas Energy Production
Benefits Decreased environmental impact Waste
to raw-material Renewable fuel production
- Rationale
- One of the laws of nature states that energy
cannot be destroyed. It can never be used up,
only transferred between bodies and converted
into different forms. It is also true that energy
can destroy. Poorly utilized energy can have a
negative effect on both the environment and
financial profits. Fortunately, there are many
good examples of sensible and efficient energy
applications, creating biogas is one of them.
Biogas is recovered from biological waste such as
sewage sludge and food and farm waste. It is an
efficient, renewable form of fuel that does not
compound the greenhouse effect since there is no
emission of carbon dioxide. Furthermore, biogas
emits considerably less nitrogen oxides, carbon
oxide, carbon monoxides and hydrocarbons than
petrol and diesel. -
- History
- Production of biogas has been a known technology
since the middle of the 19th century. In Sweden
it became more commercially used during the
energy crisis in the 70s. One of the first
commercial biogas recovery plants was built in
Sweden in the early 90s. This product evolved
from the broad experience within energy systems,
which also has positioned the CleanWater partners
in the forefront of product development. The RD
within the area has given new state-of-art low
emission and high-yield products, which covers
all the stages from design and construction to
turnkey renewable fuel production plants. - Projects
- The CleanWater's genuine experience provides Bio
Gas -Energy Production solutions, from design to
turn-key responsibility, covering the whole
production chain. That is from the wastewater
treatment plant to biogas to fuel, ending with
infrastructure for refuelling vehicles. In recent
years, many municipalities, transportation firms
and bus companies have chosen the partners of
CleanWater to design, build and service gas
refinement plants and filling stations worldwide.
CleanWater is well experienced to raise funding
together with the client for these projects.

20Planning of Water ResourcesReference project
Lyckebyån
- Background
- The new EU framework about water means that all
water resources are supposed to be planned on
river basin level. The river Lyckebyån concerns
three municipalities and three counties in the
southeast of Sweden. To have influence on coming
rules for the use of the water resource in
Lyckebyån the three municipalities Emmaboda,
Lessebo and Karlskrona intend to provide the
water authority with a vision plan. - The project
- The legal Association of River Lyckebyån,
including the three municipalities, decided that
the best way to influence on the decisions about
the acceptable use of the water resource was to
create a plan that considered all demands on the
water resource. Such a planning must involve all
stakeholders in the river basin landowners,
municipalities and their water and waste water
treatment plants, industries, hydro power plants,
organisations of different kind etc and
consider all demands for the future. Of course a
good water status must be in focus but also
variety in quantity. To achieve these goals a
Water Advise Unit will be settled as responsible
for the vision plan and the contacts with The
Water Authority. - Important experiences
- The organisation for the planning of the water
resource according to the EU Framework is shown
in this illustration. Taking initiatives the
stakeholders of the river basin will fulfil
demands from EU but will also have the
possibility to influence on decisions about the
water resource.

21Constructed WetlandReference project Kalmar
Dämme
- Background
- The water in the river Törnebybäcken is polluted
by urea from the airport of Kalmar and storm
water from industrial areas of the city Kalmar.
The environmental demands on the airport mean
that they have to purify the water especially for
the load of nitrogen. To solve the problem was
decides to design a constructed wetland. - The project
- The project started with a pre study and an
approval according to the environmental laws of
Sweden. This approval was accepted and detailed
design was followed by construction work. The
organization and the financing of the project
were shared by the airport of Kalmar and Kalmar
Municipality. The monitoring program has shown
that the nitrogen load has been decreased by
1080 percent during the running period of 10
years. Some possible adjustments have been
findings from research in the wetland.

22Systems Analysis Wastewater and Biowaste in
Gothenburg, Sweden
- Project
- The objective was to develop support for
decisions on the future sustainable management of
wastewater and biowaste in the Göteborg region.
Eight system alternatives were studied within a
time frame from now to the year 2050 with five
criteria for sustainability based on the Urban
Water Framework Hygiene, Environment (divided
into Emissions and use of Resources), Economy,
Socio-cultural and Technical function. - Conclusions
- Considerable differences between the studied
alternatives when single indicators were
considered, but small with multicritera analysis. - No indication to abandon the centralised system
of today. - Using wastewater sludge or to extract a pure
phosphorus product at the treatment plant are the
most sustainable ways to return phosphorus to
agriculture. - If more than 1530 of the nitrogen is to be
returned in wastewater and biowaste, this will
require too much energy. - Considerably more nutrients in the wastewater
than in the biowaste. It is more sustainable to
digest biowaste than to compost it. - It will always pay off to reduce the pollutant
sources in the society.

23Pilot plant for sewage treatment experiments
Hammarby Sjöstad, Stockholm
- Problem
- Sewage treatment methods are normally well
established. However, changes in effluent
demands, hydraulic or organic load or changing
prices for energy, chemicals or sludge handling
can demand changes in technology. New processes
or combinations of unit operations or alternative
equipment should be tested in smaller scale
before investment in full scale. - Solution
- An advanced pilot scale equipment was constructed
in 20022003 by Stockholm Water Ltd. The direct
purpose was to compare different methods to treat
a relatively concentrated sewage from a new city
area that was built to approach sustainability,
Hammarby Sjöstad. - The aim was to reach strict effluent limits and
possibly also get nutrients in forms that could
be accepted by farmers. After four years of
testing the equipment was in 2008 handed over to
IVL and KTH for further testing of systems and
components - There are now two aerobic and two anaerobic
complete lines (including sludge treatment and
membrane technology) that can be greatly modified
for different purposes, and used by researchers
and companies.

25Drinking Water SupplyWater Treatment Plant
Lofsdalens vattenverk
- Background
- Härjedalen in Sweden is well known for its
beautiful surroundings. The area is not heavily
populated most of the year but during the winter
season the sleepy villages becomes ski paradise
for ski yearning people coming. Heavy variations
as far as number of drinking water consumers are
concerned and long distances between the existing
water purification plants has challenged the
authorities responsible for the drinking water
supply. - The project
- Surface water is used as raw water for production
of drinking water at Lofsdalens water
purification plant. The surface water is
contaminated with organics and humic acids which
made it unsuitable for drinking without water
treatment. The demands as far as drinking water
consumption is concerned vary during the year,
the spectra is between 100-700 m3/day. In the
past the solution was flocculation and filtration
with chemicals. With the variation in flow and
low temperatures of the water at winter time the
plant needed a lot of manual attendance for
regulating the chemical addition. The maintenance
people from the main city was located 100 km from
the plant and the travel costs was big with
several visits a week to the plant. - A complete NF plant, delivered by HOH
Vattenteknik AB became the solution for cost
efficiency. The plant is totally automatized and
the steering and control of the plant can be made
from a central control room in the main city
which saves money and environment due to long
distances in the area. - Reflections
- The plant has been operating as originally
planned for over 10 years. In order to save both
economical and environmental recourses solutions
with low maintenance needs must be taken into
consideration. According to roomers the skiers in
Härjedalen enjoy their drinking water just as
much as their skiing, in other words- we are
satisfied!

26Drinking Water SupplyUppsala water treatment
plants
Background The Uppsala ridge is one of Swedens
largest ground water basins. The soil, which is
rich in lime, makes the water very hard. The hard
water dissolves copper from copper pipes in
buildings, which will cause problems. In the two
new water treatment plants, Bäcklösa and Gränby,
the water is treated before distribution. The
project Uppsala municipality awarded Malmberg the
contract to design, deliver and install all
mechanical equipment, stainless steel pipes,
fittings and instruments to both of the new water
treatment plants. The process is almost
identical for both plants and consists of the
following steps Aeration Aeration is done in
two parallel connected staircase aerators for
aeration and evaporation of carbon dioxide.
Water softening The water will be softened in
fluidized sand beds, where the hard raw water
will be pumped into the bottom of the five 11
meters high reactors. The upward flow lifts the
grit, and the bed is fluidized. By adding lye,
the pH value will increase and the lime will
deposit on the grit, which makes the grit
particles grow and settle to the bottom. A
fraction of the raw water bypasses the reactors.
It is mixed with softened water to receive the
desired degree of hardness. Filtration
Filtration is done in six two-media filters in
each plant. For backwashing the filters, there
are flush pumps and aerators for combined
air/water flushing. Bäcklösa WTP has also been
equipped with ten carbon filters for further
treatment. Important experiences After start up
of the two plants, the city today has a drinking
water of high quality that fulfills all
requirements and needs.

28Capacity Building on Cleaner Production
Hyderabad Region, India
- Background
- The cost of environmental damage is estimated to
be over 5 of Indias GDP. India currently
generates over 110,000 million litres of
wastewater a day, and over 12,000 tonnes of
hazardous waste. Untreated wastewater places
increased stress on existing water supply. With
an industrial production growth rate of 7.4 per
year, waste generation is set to exponentially
increase in the next 20 years. Proper treatment
and discharge of industrial waste is an immediate
need. - The untreated effluent of most companies will not
fulfil the requirements that should be set by the
common effluent treatment plant. Therefore a
pre-treatment is needed. - The project
- The concept of cleaner production and
resource-efficiency is very useful for
implementing a pre-treatment, but also for
process optimisation. In general, the concept
implies to treat effluents where they are
generated, and try to recycle valuable resources
like chemicals, water and energy. Also hazardous
substances and substances that might harm
treatment processes at a common treatment plant
can be prevented from leaving the factory in
harmful concentrations. - This three year project shows how to implement
solutions for cleaner production in different
Indian industries and address cleaner production
as a tool for efficient treatment of industrial
emissions and effluents. The project will
demonstrate how cleaner production can contribute
to an improved environmental situation and
sustainable water use, in combination with
economical savings for the industries. It will
also establish contacts with Swedish technology
suppliers with interesting cleaner production
solutions.

- Ellinge WWTP serves the community of Eslöv and
the Procordia Food production plant. Depending on
the season, the load varies from approximately
25,000 p.e. to 100,000 p.e. This calls for a
highly flexible treatment process. - The project
- During 2005-2006 Malmberg made, on a total
contract, a comprehensive reconstruction and
expansion for improved biological reduction of
nitrogen and sludge treatment. The contract
included site preparation, building construction,
machinery and sanitation installations, and
electrical installation and automatic control
equipment. Malmberg also carried out the project
planning, design, installation, commissioning,
fine tuning and testing for this turn-key
contract. The two old trickling filters were
converted into basins where the return sludge is
fed to Procordias pretreated waste-water and
reject water. The activated sludge basins were
modified, internal pumping of water from
Procordia was built, and new pipes and blowers
were installed. The whole sludge treatment area
was reconstructed, including new pipes and new
receiving stations for external sludge from the
municipality and industry. A sludge silo was
erected for the collection and mixing of all
sludge streams before digestion, and a mechanical
thickening step was added. A great number of new
pumps were mounted, e.g. pumps for primary and
return sludge. A sampling room was also built.
numerous rebuilding measures were also made
throughout the treatment plant. The contract was
carried out in an atmosphere of excellent
co-operation with Eslöv Municipality, as well
process personnel at Ellinge WWTP. - Reflections
- There has been a thorough analysis of treatment
results from the two years following start up,
evidence that the chosen technology works to full
satisfaction.

35Bio Gas Green Gas concept of BiogasKönnern
Biogas upgrading plant
- Background
- The Biogas Plant Könnern in Germany was planned
to produce biogas from green gas products and
then to be burnt in gas engines (CHPs). According
to Malmbergs customer, this was in the beginning
of the project the best solution according to the
subvention guidelines, EEG. A new version of the
subvention was launched and a technical bonus was
added so that upgraded biogas by Malmberg was the
most profitable solution. - The project
- Malmberg Biogas got in April 2007 an order to
deliver the biggest biogas upgrading plant in
Germany, also the biggest one in the world to
produce clean methane to the natural gas grid
from green products. The plant is based on the
principle of a water scrubber and Malmberg
Technologies in the field of upgrading biogas had
then been focusing on the best solution for
optimizing the upgrading plant together with the
production plant. So that biogas in the total
values chain could be produced to the lowest
cost. - The scope of delivery was an upgrading plant
including injection station to the natural gas
grid the delivery time was set to inject gas at
20 December 2007 in Könnern. The upgraded biogas
should be distributed by the gas company MITGAS
(owners RWE), and to be sold as a new product
launched as MitBioGas, both private and
commercial purpose. The profit for the customer
was to sell green gas at the same cost as for
fossil natural gas.

36Bio Gas Green Gas concept of BiogasKönnern
Biogas upgrading plant
- Important experience
- In the past the traditional way of using biogas
in Germany was to inject electricity direct to
the electric grid at the biogas production plant.
- With Malmberg Biogas the customer has found a new
way through the natural gas grid the customer
can higher the efficiency in total by injecting
the electricity in other locations and then make
use of the heat losses, which today stands for
2/3 of the input to the gas engine. Heat resource
by biogas plants was in the past seen as a
surplus, today must the total energy demand be
optimized. - New heat solutions are implemented for a total
decreasing of the energy demand. Energy from
biogas will therefore only allow heat from green
energy, which has resulted in that products with
low heat demand, both in production and
upgrading, will be the most optimal ones.

Plant
- Background
- The municipal biogas plant, situated at Tuvans
wastewater treatment plant in Skellefteå,
receives domestic waste, slaughterhouse waste and
liquid waste - The project
- The plant has three receiving units, of which two
are for source-separated domestic waste and one
for slaughterhouse waste. - The units for domestic waste are equipped with
four bottom screw conveyors each for
decomposition and homogenisation of the incoming
substrates and discharge to the transport
conveyors for further transport to two mixers. In
the mixers, the substrate is diluted to the right
DS concentration. From the mixers, the substrate
is led to a bio-separator for separation of
non-digestable material. After that, the
substrate passes through a disperser for further
decomposition and is then led to the buffer
tanks. - The slaughterhouse waste is transported with a
bottom screw conveyor to the disperser for
decomposition and from there to the buffer tanks.
- Liquid waste is pumped to the buffer tanks via
the disperser. - From the buffer tanks the substrate is pumped to
two hygienisation tanks where the substrate is
heat-treated at 70 C before it is pumped to the
digester. To avoid too high temperature in the
digester, the incoming substrate is cooled with
the dilution water flow that is recycled to the
process. - The produced biogas is then upgraded to vehicle
fuel. - .

water treatment plan
- Background
- Himmerfjärdens waste water treatment plant south
of Stockholm has a load of 300.000 pe. Major
energy consumption is found in the inlet pumping
station biological treatment with full
nitrification Sludge is digested and a large
portion of the biogas is flared. A sharp
increase in electricity cost triggered an energy
conservation project to reduce opex. -
- The project
- An energy survey with sensitivity analyses was
undertaken in co-operation with experts from
university and consultants. The project was
initiated by Himmerfjärdens WWTP who financed the
studies that resulted in significant energy
savings and several projects being implemented,
e.g. refurbishment of inlet pumps (energy savings
of 23 percent), improved thickening before
digestion, (lower heating cost and higher biogas
production), a new gas engine connected to a
blower, reduce electrical energy consumption with
350 kW, upgrading biogas to vehicle fuel creating
a revenue, calculated payback within 3 years. - Important experiences
- Based on a thorough evaluation and sensitivity
analyses significant energy savings and optimized
usage of biogas, heat and electricity can be
reached

- The initiative behind SymbioCity CleanWater
Offer, was to a larger extent promote the Swedish
model for integrated water and wastewater
management abroad. Behind the initiative are the
internationally most well merited and experienced
private and public water management corporations
of Sweden. - SymbioCity CleanWater Offer is organised as a
consortium and is managed by the Swedish
Environmental Technology Council, Swentec. The
consortium which constitutes of more than 50
members includes all the resources necessary for
long and prosperous bilateral collaborations,
involving the Swedish private sector,
municipalities, research institutions, funding
and Swedish governmental institutions. - All-in-all the SymbioCity CleanWater Offer has
been involved in more than 10,000 project
conducted in over hundred countries!

42The Swedish knowledgebase
- Nothing has greater impact on our lives than
water. Water is fundamental for our health,
comfort and prosperity. We believed water to be
an endless resource, and nature would take care
of any irresponsible misuse. Today, we know
better. We know that careless water usage will
cause a great environmental impact. -
- Members of the SymbioCity CleanWater Offer have
worked with water management for over 140 years.
Export started 1903 with a sewage plan for St.
Petersburg, Russia. In the early days focus was
on providing freshwater and fire fighting,
thereafter sanitation by sewage treatment. - Since the 1960s the environmental aspects have
been the focus for Sweden, with a major
construction period of wastewater treatment
plants in the 60s and 70s. This has resulted in
what might be the most far-reaching effluent
standards in the world being enforced in Sweden.
The water issue is ever evolving. Today the
SymbioCity CleanWater Offer focus on integrated
wastewater and water management, which optimizes
water and energy resources from a broader
perspective including environmental, social and
economical effects, reaching from a whole region
to a single plant. -
- The development in Sweden has given the
CleanWater members an extensive experience and
knowledgebase. Only in Sweden, the CleanWater
members have designed, constructed, serviced and
maintained more than 4000 public wastewater and
water treatment plants and approximately 30
meters of piping per capita to handle the
infrastructure. This knowledge and experience has
been exported throughout the globe, to more than
100 countries and 10 000 projects!
