Biological STP (Sewage Treatment Plant)

Soil Bio Filtration -an ecosystem created using soil, Nutrient rich waste water & solar energy wherein our waste becomes food for others. It is a method of rejuvenating  wastewater by charging sewage with new life and vitality using natural processes. 

Urine contributes high level of Nitrogen and Phosphorus to sewage. when its nutrient rich waste water enters fresh water bodies likes lakes and rivers, the dissolved oxygen [DO] level drastically reduces, leading to fish kill.Bio STP efficiently removes these nutrients and also increase the DO level of treated water.

Increase in DO level, triggers biological recurrence and rejuvenation.
