Water Treatment Products

We have a bouquet of products which are modular and containerised, allowing us to quickly build compact solutions to treat all types of waste water.

These modules are typically built by us either for pre-treatment or post treatment for our Systems.

Reverse Osmosis based WTP

Grewa-O is an innovative, technologically advanced RO module that governs the point of use/reuse of water. It is compact, programmable and removes dissolved and suspended solids, chemicals, pesticides and microbial impurities. Grewa-O unit with pre-treatment (up to 1500 LPH) can be accommodated on a single skid of (2.1 x 1 x 1.6) meters.

Grewa-O is made in two variants:

BW-LRO (Brackish water low energy option suitable up to inlet TDS 4,000ppm)
BW-SRO (Brackish water standard option suitable up to inlet TDS 8,000ppm)

UF Modules

Grewa-U Ultra filtration system provides complete Point of Entry (PoE) and Point of Discharge (PoD) Filtration to remove impurities < 0.5 microns. The ultra filtration membrane effectively reduces turbidity, particulates, cysts and certain microbiological contaminants for safer, cleaner water.

Longer Membrane Life:

The electronically controlled flushing system is designed to initiate self-cleaning back-flush cycle when the membrane reaches the programmed capacity. This maximizes the membrane capacity and service life. CEB (Chemically Enhanced Backwash) can also be done to improve longevity of the membrane.

Power-saving System:

This system optimizes flushing cycles and consumes power only for flushing, thus reducing energy consumption to a great extent. It also provide real-time performance monitoring.

In-built critical Diagnostics:

The critical system diagnostics feature ensures continuous operation in case of power outages or intermittent power. This ensures the integrity of the membrane is not compromised.
