Antiscalant Software Our Proton Aqueous Membrane
Chemistry Calculator is the worlds most powerful
antiscalant projection software. Proton can be
used to design a new RO/NF system, performs a
complete suite of hydraulics calculations, and
accounts for tail element concentration
polarization in its scaling calculations. The
software accounts for ion activity and for over
130 ion complexes making it the most accurate
projection software in the industry. It is the
only membrane software to calculate the
saturation and precipitation potentials for over
50 scales at the entire operating pH range of 1
11. Proton also projects water quality, and
reliably predicts rejection of contaminants such
as boron, arsenic and bromide. Learn More
Membrane Cleaning Studies AWC can perform
cleaning studies to identify the best cleaning
protocol and most effective cleaning chemicals
for a particular fouling situation. Learn
More Off-site Membrane Cleaning For industrial
facilities that do not have clean-in-place (CIP)
systems, AWC can perform multiple membrane
element cleanings in our facility to ensure
stringent cleaning procedures and to optimize
results.

Learn More Membrane Autopsy AWC is the only
membrane specialty chemicals company that
performs all its analytical services in-house.
We invite customers who are interested to witness
the various parts of the autopsy process,
including electron microscopy with x-ray
spectroscopy and elemental mapping
(SEM/EDS/PED/SEI), FTIR, Raman, and other
state-of-the-art analytical testing. Owning our
equipment allows us to be more thorough, testing
samples along the entire length of a membrane,
and analyzing the membrane surface after a
cleaning study to search for mechanical damage
that would not be detectable when covered by
foulants. Our autopsy reports are widely reputed
to be the most thorough in the industry Learn
More Laboratory Services AWC has the capability
to conduct water analyses and membrane
antiscalant projections for Reverse Osmosis and
Nanofiltration systems. AWC can also conduct
chemical dosage determinations for our
antiscalants, coagulants, and flocculants. For
clients with extreme scaling or inorganic
fouling conditions, AWC can synthesize identical
water chemistries in the lab to determine
optimal pretreatment and control limits. Water
Analysis Complete inorganic water analysis for
NF/RO antiscalant projections and corrosion
inhibitor recommendations. Learn More ROSSEP
Process Lab simulation for prediction of scaling
in NF/RO systems. The ROSSEP process can be used
to verify calculated software predictions for
maximum recovery, optimal pH, and lowest
effective antiscalant dosage. Learn More
Materials Characterization Identification of
unknown deposits or materials using a variety of
analytical techniques. Learn More On-site
Membrane Cleaning AWC can provide personal and
portable cleaning equipment for membrane
cleanings at customers sites. AWC can also
train customers personnel on the operational and
cleaning processes of RO plants. Learn More
System Monitoring Optimization The AWC System
Monitoring and Optimization Solution has been
developed for Long-Term and Short-Term
Monitoring and Performance Optimization for
RO/MF/NF/UF Membrane Filtration systems. We can
provide a strategy for formulating appropriate
long-term
3
monitoring programs that can be implemented at
lower costs for maximum production efficiency.
AWC uses scientific and statistical methods
applied to site-specific data that accounts for
relevant current and historical site data to
develop an optimization plan for the current
system and the best possible solution. AWC can
also help clients in start-up of new systems and
will perform system normalization of data
provided by the client to ensure that their
membrane system continues to operate with
optimal permeate production and minimal power
consumption. Learn More Pilot Studies AWC is
able to conduct pilot studies using state of the
art pilot R.O. units designed to simulate actual
site conditions. These pilot plants are mobile
and can be dispatched to the customers plant
site on short notice. Through these studies, our
engineers are able to recommend effective
solutions to persistent scaling and fouling
problems resulting in a trouble-free operation
and reduced operating cost for the
customer. Learn More Products AWC provides
customized solutions for membrane cleaning, based
on your feedwater chemistry, your operating
restrictions and your treatment goals. Our aim is
to ensure that your membrane system operates at
maximum productivity without impacting your
desired water quality. Reverse Osmosis
Nanofiltration Reverse Osmosis Nanofiltration
are now being used in a broad range of
applications including potable water, mining,
leachate, municipal and industrial reuse. AWC
has developed an extensive line of RO
antiscalants, reverse osmosis membrane cleaning
chemicals and biocides to control and reverse all
scales and foulants that can form in these
applications. Pretreatment Multimedia Filtration
(MMF) is often used upstream of RO/NF to remove
suspended solids that can cause plugging of
membrane feed channels and damage the membrane
surface. However, MMF media is only efficient at
removing particles larger than 20 50
microns. AWC has developed a line of membrane
compatible organic and inorganic coagulants that
agglomerate smaller silts, clays and colloids
into larger clusters that are more efficiently
filterable. All polymers have been tested
extensively to ensure safe use with RO/NF
membranes even in case of slight
overdosing. Learn More Reverse Osmosis (RO)
Antiscalant Our high performance reverse osmosis
(RO) antiscalant are effective at remarkably low
dosages. The use of AWC antiscalants can
eliminate the need for acid dosing, enable
plants to operate at higher recoveries, and
reduce cleaning frequencies. AWC has developed
highly effective inhibitors that are unparalleled
in the industry at controlling the
4
most challenging scales. All AWC antiscalants are
NSF approved for use in potable membrane
systems. Learn More RO Biocides AWC RO biocides
have been specifically selected for use with
RO/NF membranes. Our product line includes
oxidizing and non-oxidizing biocides that are
selected based on water quality and frequency of
biological fouling. Learn More Dechlorination
Chemicals AWC dechlorination chemicals have been
specially formulated for long term shelf-life and
are odor-free. In addition to neutralizing free
and combined chlorine to protect RO/NF
membranes, they also deactivate all other
oxidizing and non-oxidizing biocides this makes
them essential tools for environmental
discharge. Learn More RO Membrane Cleaning
Chemicals AWC RO membrane cleaning chemicals are
highly effective for removing even the most
stubborn scales and foulant from RO/NF membranes.
High pH and low pH chemicals are available in
liquid and powder form. All AWC cleaning
chemicals are NSF approved for use in potable
membrane systems. Learn More Microfiltration/Ultr
afiltration Chemicals MF/UF systems are widely
used for treating surface and wastewater, and are
sometimes applied as pretreatment for RO/NF
systems. AWC has developed an extensive line of
antiscalants and cleaning chemicals for use with
MF/UF systems. Membrane Antiscalant MF/UF
membranes do not reject salts, and scaling is
therefore not a common occurrence. However,
scaling can occur under certain conditions,
especially in systems where air sparging is used
frequently or high pH chemically enhanced
backwashes (CEB) are applied. AWC has developed
a line of membrane antiscalants that are approved
for use in potable MF/UF systems. All AWC
antiscalants are NSF approved for use in potable
membrane systems. Learn More Cleaning
Chemicals AWC MF/UF cleaning chemicals are
proprietary formulations for extremely stubborn
foulants. While aggressive commodity chemicals
such as bleach and caustic soda are commonly
used with PVDF and PES membranes, they are not
always effective at removing organic foulants.
AWC has created a full line of MF/UF cleaning
chemicals to address the varying chemical
tolerances of PVDF, PES, PAN, PP, and CA
membranes. All AWC cleaning chemicals are NSF
approved for use in potable membrane systems.

Chemicals and Potable Water Corrosion
Inhibitors RO permeate tends to be corrosive to
metals. In potable water distribution systems,
this can cause compliance issues with the EPAs
lead and copper rule, and consumer complaints
about red water and rust staining. In industrial
systems, corrosion can damage expensive
equipment and reduce efficiency. AWC has created
a line of corrosion inhibitors designed
specifically for use with aggressive RO treated
water. We manufacture corrosion inhibitors for
potable water distribution as well as chillers
and hot water systems. Potable Corrosion
