Aerobic Plant FactorsTO MAINTAIN LIFE

• pH
• B.O.D.
• C.O.D.
• Suspended Solids
• Settable Solids
• Fats, Oils, Greases
• Nutrients - nitrogen phosphorous

4
Membrane Filtration

• Membranes
• Poly material
• Layered to generate surface area
• Very small filtration levels
• pH specific on most
• Susceptible to clogging
• Maintenance intensive

What is oxidation?

• Simply put The adding of an oxygen atom
• You are changing the composition of a molecule in
  order to change how it behaves

6
What is Ozone?
7
Ozone

• The energy stored to create ozone wants to react
  by forcing the extra oxygen atom on an organic
  molecule
• The resulting reaction is CO2 H2O

8
Oxidizers

• Fluorine (F-)
• Hydroxyl Radical (OHo)
• Ozone (O3)
• Chlorine (Cl-)
• Bromine (Br-)
• Hydrogen Peroxide (H2O2)

9
Oxidizers

• These oxidizers do not contribute to TDS
• Hydroxyl Radical (OHo)
• Ozone (O3)
• Hydrogen Peroxide (H2O2)
• UV light

10
What is Catalytic Oxidation?

• A combination of multiple oxidants to form an
  hydroxyl radical OHO.

How is the Hydroxyl Radical Formed?
12
Thermo Oxidation

• Thermally destroy organic compounds
• Evaporation process that completely removes the
  water from the solids.

13
Adsorbent Systems

• Clay treatment
• Bentonite
• Emulsified organics
• Heavy metals
• BOD

14
Evaporation

• Reduce water from stream
• Reduction of volume for cost savings
• Natural or man made
