  39. 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)

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 Constructed Soil Filter (CSF) Media Formulation N2+H2O = NH3+O2 Natural O2 Additives: Weathering Microorganisms (Task Force) + Geophagus worm (Controls ecology) CO2 + H2O = HCO3 - + H+ Primary mineral + CO2 + H2O = M+n + nHCO3-+ Soil/clay/sand Clear Effluent Components of CSF Media

  41. 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

  44. 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
