Phytorid DetailsMechanism
1) Biochemical Oxidation of organics
2) Nitrification/denitrification
3) Phosphate uptake4) Anaerobic treatment
zones at bottom
• BOD reduction : O2 diffusion in liquid is limiting
factor in any STP, No matter how it is supplied
• Improved surface area helps Mass Transfer

Salient Features• Rapid Aerobic Composter is scalable from
household to community to small town• Aeration systems provides no foul smell• No Electricity required• No vector nuisance• Accepts biodegradable waste dry or wet• Specialized microbial culture • Low footprint• Stabilized manure in 18 days• Easy O&M
Organic Waste to Energy
Salient Features
• Community level• Converts biomass to methane for combustion• Accepts dry and wet biomass (need 20% cow dung)• Already implemented in field
Water Supply
Toilet eABR
Phytorid
Disinfection
• Small nuclear units• No mechanical/electrical parts are required• Easy to install, even in existing toilets• The system requires no aeration or any other active controls• A consortium of bacteria works for organic waste conversion• One time addition of microbial culture• System is installed underground and therefore no dedicated space
required• BOD and COD reduces below 30 and 100 mg/L respectively• No maintenance
