 Grewa-O
Grewa-O is a unique, technologically advanced, compact and programmable RO module which governs the point of use/reuse of water. It can be used for drinking, commercial and process applications in industrial, commercial and municipal water treatment. Grewa-O removes dissolved and suspended solids, chemicals and pesticides and microbial impurities.
Grewa-O is available in two variants
- BW-LRO (in brackish water low energy option)
- BW-SRO (in brackish water standard option)
Features
- Modular and compact system
- Skid Mounted base frame with pre-treatment
- Modular and compact system. (Grewa O Units up to 1500 LPH and Pre-treatment, will be accommodated on a single skid of 2100mmx1000mmx1500mm)
- Programmable central control panel
- Provision of both low and high pressure switch
- Optimised set points for permeate flow enhancing life and durability of membranes
- High/Low pressure shutdown with Auto restart
- Logic controlled auto flushing
- Provision for reject recirculation
- Reliable instruments for product, waste and recirculation flow rates at quality measurements
- Remote monitoring, if and as required
- Ready to use plug and play systems
Applications
- Drinking water, industrial applications, including boiler feed and process water
- Residential, commercial and industrial
- Roughing de-mineralisers to remove total dissolved solids
- TOC reduction and polishing treatment for recycling high TDS wastewater recirculation.

The selection chart is based on a feed TDS of 1000ppm and at temperature at 25C
The feed water is assumed to be free of colour oxidising matter and oil and grease and heaving heavy metals<0.2 ppm and silica<25ppm. Variations in the inlet conditions will have heavy metals<0.2ppm and silica <25 ppm. Variations in the inlet conditions will have a implication on recovery and permeate TDS.
