PROCESS CHEMISTRY

Aerobic Respiration

(CH2ONxPySzKy)n + nO2 + nH2O = nCO2 + 2nH2O + Mineral (N, P, S, K) + Energy (1)

Photosynthesis

nCO2 + 2nH2O + Minerals (N,P, S,K) + Sunlight = [CH2ONxPySzKy]n + nO2 + nH2O (Photosynthesis) (2)

Nitrogen Fixation

N2 + 2H2O + Energy = NH3 + O2 ( in soil) (3)

N2 + 2H2O + Light = NH3 + O2 (in water) (4)

Acidogenesis

 4C3H7O2NS (cell mass) + 8H20 = 4CH3COOH + 4CO2 + 4NH3 + 4H2S + 8H+ + 8e- (5)

Methanogenesis

 8H+ + 8e- + 3CH3COOH + CO2 = 4CH4 + 3CO2 + 2H2O (6)

Adding 5 and 6 give overall biomethanation chemistry

 4C3H7O2NS + 6H20 = CH3COOH + 6CO2 + 4CH4 + 4NH3 + 4H2S (7)

Mineral weathering

 CO2 + H2O = HCO3 - + H+ (8)

Primary mineral + CO2 + H2O = M+n + n HCO3 - + soil/clay/sand (9)

Nitrification

 NH3 + CO2 + 1.5O2 = Nitrosomonas + NO2- + H2O + H+ (10)

 NO2-+ CO2 + 0.5O2 = Nitrobacter + NO3- (11)

Denitrification

4NO3- + 2H2O + energy = 2N2 + 5O2 + 4OH - (12a)

Anammox NO2- + NH4+ = N2 + H2O + energy (12b)


Components of csf media

Influent Waste Water

Plantation: Photosynthesis

Media: Respiration

(CH2ONxPySzKy)n+nO2+nH2O = nCO2+2n H2O+ Mineral + Energy

NH4+NO2 = N2+H2O

4C3H7O2NS + 8H20 = 4CH3COOH + 4CO2 + 4NH3

3CH3COOH + CO2 = 4CH4 + 3CO2 + 2H2O

nCO2+ 2n H2O+ (N,P,S,K) + Sunlight= [CH2ONxPySzKy]n+

nO2+ H2O

Why weathered environment

Why Weathered Environment ?

Oceans: 160 per mL;

Soil: 6400-38000 per g;

Sewage: 70 per mL

  • Microbial Diversity (Curtis & Sloan, Science 309, 2005)

    Soil: 1012-1016 cells/g soil; 105-106 generaWater: 103 genera

  • Energetic (ca.)

    Land: 3.2 kJ/g.live C.yr

    Water: 700 kJ/g.live C.yr

  • Oxygen diffusion coefficient (Perry’s Handbook, 1999)

    Soil : 10-5 m2s-1

    Water : 10-9 m2s-1

    Solubility of Oxygen in water is very low (0.3 millimol/L at 200C)

  • Immobilization of pollutant; hence high reaction rates Vs local pollution becomes global; low reaction rates due to dilution

  • Heterogenous system; housing multiple microenvironment viz. oxic, anoxic and anaerobic within same niche Vs only one within the same niche..

  • Has multiple food chain and food web

Media culture

Media & Culture

  • Underdrain:- Stone rubble of various sizes ranging upto Gravel (200.0-2.0 mm), Very coarse sand (1.0-2.0 mm), Coarse sand (0.5-1.0 mm), Medium sand (0.25-0.5 mm), Fine sand (0.1-0.25 mm)

  • Media:- Formulated from soil as required and primary minerals of suitable particle size and composition

  • Culture:- Geophagus (Soil living) worm Pheretima elongata and bacterial culture from natural sources containing bacteria capable of processing cellulose, lignin, starch, protein, also nitrifying and denitrifying organisms. Anaerobic organisms for methanogenesis. For industrial wastes, development of appropriate culture required

  • Additives:- Formulated from natural materials of suitable particle size and composition to provide sites for respiration, CO2 capture

  • Bioindicators:- Green plants particularly with tap root system
