In bio digestor technology anaerobic microbes perform fermentation under anaerobic conditions in anoxic environment. Since this is anaerobic condition, almost 99% organic waste mater gets degraded with hardly any sludge left over or H2S produced.
Bio-STP tanks are made up of FRP material. These are airtight and only treated effluent comes out of the tank.
The microbial load used in this process are developed by DRDO and can bio-degrade human waste (organic waste) in wise range of temperature and aby cleaning agent (in moderate quantity).
Shree Jee Bio-STP gives flexibility to design as per site conditions and customer’s comfort. We have a wide range of Bio-STP suitable for small houses, apartments, societies, factories and institutions. We have successfully installed more than 500 Bio-STP across the nation.
