Reasons For Wastewater Treatment

• Reduction of Organics (BOD/COD)
• Reduction of Inorganics like ammonia
• Reduction of Suspended Solids
• Public Health
• Infant Mortality
• Reduction of Micro-organisms

HESS
Primary Reason to Treat Wastewater Dissolved
Organics

• Sources
• Domestic Wastewater
• Process Water in Factories
• Paper Mills
• Oil Refineries
• Food processing
• Dairies
• Iron and Steel Mills

HESS
Most Economical Treatment

• Biological Treatment (Aqua Clean)
• Treat Large Volumes of Water
• The Bacteria Reproduce
• Reduction of Other Expenses
• Energy for Aeration
• Sludge Handling

HESS
Bacteria work with natural processes

• Life Cycles (Biogeochemical Cycles)
• Carbon Cycle
• Nitrogen Cycle
• Sulfur Cycle
• Phosphorous Cycle

Basic Biological Treatment Processes

• Aerobic
• BOD N P O2?CO2 H2O cells
• Facultative-
• CO2 NO3 O2 ? NO3 CO2 Cells
• Anaerobic-
• BOD N P ? CH4 H2S CO2 cells

Common Treatment Technologies

• PhysicalChemical particulates, colloidal
  organics, metals
• Flocculation
• Settling
• Biological Dissolved organics inorganics
• Convert dissolved organics to CO2, H2O and cells.
• Settle out cells.

Common Treatment Technologies

• Carbon Dissolved organics, metals, etc.
• Ion Exchange Removal of metals, other cations
  and anions
• Disinfection
• Chlorine
• Ozone
• uv light

16
HESS
Minimum Requirements for Biological Treatment

• Residence Time
• Adecuate pH Range
• Adecuate Temperature Range
• Correct Mix of Bacteria

17
HESS
Types of Biological Systems

• Suspended Growth
• Tank
• Lagoon (with or without aeration)
• Activated Sludge
• Anaerobic System

18
HESS
Simplified Kinetic Model

• Se Si
• 1 Xc Ks Øh
• where Se and Si - are effluent and influent
  concentrations of substrate, respectively
• Xc cell mass in gm/L
• Ks specific rate coefficent, gms/Lday
• Øh- hydraulic residence time, days.

19
HESS
Most Important Point for Successful Biological
Treatment

• Adequate Concentration of Appropriate
  micro-organisms apropriados to contact water to
  be treated for a sufficient amount of time for
  bacteria to multiply.

HESS
Bioaugmentation Concept

• Bioaugmentation
• The purposeful introduction of a biological
  system with a pre-selected organisms to enhance
  the numbers, degradative capacity or kinetic
  activity to enhance the efficiency of the system.
