Water Recovery from Domestic Sewage

Dissolved natural and manufactured organics, a high concentration of suspended particles (mainly faeces), and a diverse range of pathogenic and non-pathogenic organisms define residential wastewater.
Domestic wastewater has been treated using a variety of methods. However, all of the processes have drawbacks, such as a large footprint, the emission of foul gases, the generation of foam, and the production of a large volume of sludge.
Enviro Janitors presents a novel technology to treat the wastewater with the following characteristics.

Low footprint

Low electrical energy consumption

Low Operation & Maintenance cost

No odour emission

Very low sludge generation

Complete recyclability of treated water

25+ Years of life span without any alteration and replacement of materials.

What makes us better than conventional treating plants!
