Sewage Treatment Products

We have a bouquet of products which are modular and containerised, allowing us to quickly build compact solutions for sewage treatment.

MBR based STP

Grewa-M is a fully automatic and self-contained packaged treatment product designed to meet Wastewater treatment challenges faced globally today. It’s a state-of-the-art Membrane Bio Reactor that combines two technologies:

Biological : Enhanced biological treatment incorporating BNR

Physical : Immersed membrane filtration system

SBR based STP

Revolutionary Grewa-RS is the next step in evolution of our next generation Grewa-R range of products. Developed on the philosophy of providing best-in-class, packaged, fully automatic & single tank SBR technology, GREWA-RS is equipped with unique features such as capability to handle variable loads (10% to 110% of design capacity), lowest footprint, low operating and maintenance cost (up to 50% lower than conventional technology) and fully automated and robust operations.

MBBR based STP

Grewa B is a robust sewage treatment based on Moving Bed Bio Reactor system.

Grewa B is an attached growth process and uses PP/ Polyethylene bio film carriers providing large surface area which is operated under aerated conditions.

This is a flow through process, which attains high level of BOD reduction.

Grewa B systems are compact, salable and have high operational efficiency.

Grewa B systems are ideal for commercial complexes, residential units, hotels and office complexes.
