Title: Wastewater Treatment Technologies


1
Wastewater Treatment Technologies
  • Bioremediation
  • Coagulation/Floc
  • Membrane Filtration
  • Filtration/Gravity
  • Oxidation (Ozone)
  • Thermal Oxidation
  • Encapsulation
  • Evaporation

2
Aerobic Plant
3
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

5
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.

O3
OHO
UV
H2O2
11
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
