BIO-DIGESTER

Biodigester technology has been developed for resolving the problems of un-decomposed human waste. The innovation degrades and converts the human waste into usable water and gasses in an eco-friendly manner. The generated gas can be utilized for energy/ cooking and water for irrigation purposes.

The process involves the bacteria which feed upon the faecal matter inside the tank, through anaerobic process which finally degrades the matter and releases methane gas that can be used for cooking, along with the treated water.

The Bio-digester tank can be manufactured and customised as per the requirement.

Salient Features:

• No bad smell in toilets from the tanks
• Faecal matter in the tank not visible
• No infestation of cockroaches & flies
• No clogging of digester
• Effluent is free from off odour and solid waste
• Reduction in pathogens by 99%
• Reduction in organic matter by 90%
• No maintenance required
• No requirement of adding bacteria/ enzyme
• No need of removal of solid waste
• Use of phenyl is permitted upto 84 ppm

Areas of Applications

Bio-Toilets Septic tanks Bio toilets can function at any atmospheric temp between -55 to 60 degree C. The bacterial consortium degrades night soil at temp as low as -55 degree C and produces colourless, odourless and inflammable bio gas containing 50 – 70% methane. The main constituents of Bio Toilet are Pre fabricated above the ground shelter and Bio Digester tank. Bio digester tank is a cylindrical structure with the provision of inlet for human waste and out let for Bio gas. Temp in the bio – digester is maintained between 5-30 degree C. A person can use the toilet which is connected to the bio-digester. Night soil degradation occurs through microbial reaction which converts it into bio gas. The smell of night soil, the disease causing organisms in the night soil and the solid matter are eliminated totally. On dry weight basis 90% of the solid waste is reduced. The gaseous effluent (bio-gas) is continuously let off to the atmosphere. Bio Gas can be used for various energy incentive activities like cooking water and room heating. Liquid effluent can be drained to any surface or soak pit with out any environmental hazards. CONSERVES Water, Energy Space, Environment Money, Time Promotes Hygine And Ensures Good Health TYPES OF BIO TOILETS Stationary Toilet (ST-Series) Non Temp. Controlled – For plane areas - Standard ready made options available in 4 Pan , 2 Pan and single pan Temp. Controlled – Solar Powered, For Hilly and cold regions - Standard readymade options available in 4 pan , 2 pan , 1 pan Independently Mounted Mobile Toilets (IMMT- Series) For Rail Coaches For Buses For Ships and Boats TECHNOLOGY BEHIND BIO TOILET Human waste disposal in high altitude and low temp areas, Moving Railway coaches, Buses, Big Cities, Mines, remote areas, Beaches, Rural areas, long distance buses is a burning problem. The problem has further aggravated in glaciers where ambient temperature drops to -40 degree C and lower. The low temp stops/ delays the natural bio-degradation of the waste leading to its preservation (accumulation) for long time resulting in environmental hazard. Local heating by direct sunlight exposes the waste buried in the ice causing nuisance and foul smell. The melting ice takes the waste to rivers disturbing the aquatic eco system. More over human waste is also responsible for spreading of water born diseases like typhoid, cholera, Shigellosis, Amebic Dysenteries, Diarrhea etc. This technology is suitable for any area/ application in India. The process under this technology culminates in to treated effluent which is free from Pathogens and is also environmentally acceptable. The technology has major two components: a- Low temp active inoculums b- Temp controlled Bio digester A consortium of anaerobic bacteria has been formulated and adopted to work at temp as low as 5 degree C. This is the component which acts as inoculums (seed material) to the bio digester and converts the organic waste into methane and carbon-dioxide. The anaerobic process in- activates the pathogens responsible for water born diseases. Bio digester serves as reaction vessel for bio methanation and provides the anaerobic conditions and required temp for the bacteria. The optimum temp is maintained by microbial heat, insulation of the reactor and solar heating. SALIENT FEATURES Suitable for sub zero temperature of Himalayan Region, Glaciers, Railway coaches, Buses, Highways, Remote areas, sea ports, Mining area, metro cities etc. Suitable for Mobile Toilet applications 00% maintenance free, continuous biological process. Complete elimination of pathogens. Economically viable. No dependence on the limited and costly conventional energy sources. Can be installed and made operational in 12 hours only. Inoculums charging is only once during the entire life of Bio Toilet. No need of connectivity to the sewage line, septic tank. No disposal of sludge is required. Routine cleaning chemicals like phenyl, soap, Kerosene etc. do not harm Bio Toilet or the inoculums.
