Water is fast becoming a Strategic commodity in many parts of the world.
Sewage and WasteWater Treatment is now becoming most critical due to diminishing water resources, increasing wastewater disposal costs and stricter discharge regulations, from the Pollution Control Regulatory authorities, who have lowered permissible contaminant parameter levels in all waste streams across the consumer spread. It is a known fact that municipal sector consumes significant volumes of water and consequently generates considerable amounts of wastewater. Municipal wastewater is a combination of water and water-carried wastes originating from homes, commercial and industrial facilities, and institutions.
Incorporation of state-of-the-art treatment methodologies and Innovative ways to process wastewater through compact sewage treatment plants and facilities appears to be the only way forward.
Municipal sewage and wastewater is the combination of liquid or water-carried wastes originating in the sanitary conveniences of residential, commercial, industrial, medical and entertainment facilities and institutions. In addition to any groundwater, surface water and storm water that may be present, untreated wastewater has been to contain high levels of organic material, varying pathogenic microorganisms, nutrients and sometimes even toxic compounds. All this put together, only leads to Environmental and Health hazards and therefore the need to immediately transport it away from its source of generation for appropriate treatment, before final disposal.
The ultimate goal of any Municipal Corporation through its Sewage and Wastewater Management program is the protection of Environment which directly impacts Public Health and Socio-Economic well being.
De-centralized process & Treatment, at " Point of Generation " source the only solution !
Our grewa range of system solutions clean, treat and recycle wastewater to such a high quality that it can be re-circulated in closed systems instead of simply discharging it in sewers or use only for Gardening and Horticulture. Our re-cycling strategy is the base of a “No-Waste”
concept on which we have built our Technology.
We firmly believe that all systems must be guided by customer benefit. Therefore, in addition to the quality of the treated effluent, we have ensured and improved the overall cost efficiency of all our systems. We have brought in new standards to improve the ease of maintenance and reduce the energy consumption on a “Continuous Operational Cycle” basis for the grewa range.
It needs to be understood and accepted that Environmental protection is lagging behind and that situation must improve through conscious efforts.
There is no cheaper solution than draining polluted water into Nature.
But is this right ?

Grewa-R STP in the true sense, processes sewage and waste water in a very simple, reliable and economical way. The system works on an innovative and State-of-the-Art Treatment Control concept, reducing most of the conventional Energy guzzling and Noisy moving equipment. This ensures that Grewa-R operates at minimum cost, high efficiency across varying loads and produces almost negligible yet fully-digested sludge.
Grewa-R process ensures that treated wastewater is made Recycle-Ready. Due to the dramatic reduction of energy input and resulting Low Operating Costs, investment in Grewa-R is recovered quickly.
Grewa-R is a packaged and purpose-built systems suitable for biological treatment of domestic and industrial wastewater. While packaged treatment plants are produced for typical domestic discharges, purpose-built installations to suit the municipal, industrial, commercial, leisure, hotel and trade discharges which have variable characteristics and cannot be accommodated by conventional plants, can be achieved with Grewa - R
Grewa-R has been designed after studying the performance parameters and operating characteristics of existing variations in conventional plants and selected on the basis of low first cost, flexibility, ease of maintenance and process stability.
Grewa-R has redefines “Operation at Fingertips” it is fully automatic:
- Logic based touch pad operated control unit configuring all unit functions Automatic motor starter reset in the event of power failure (which is instantaneous with per resumption)
- Automatic drive motor reversal with time delay recycle in the case objects, which would jam an ordinary STP are identified
- Remote Access to operator console from anywhere in the world, if required
- Sequential methodology coded into logic for optimising performance. Scalable and Flexible. Completely automatic sludge inventory control systems improving the efficiency and effectiveness of sludge digestion and treated water quality.

Category: Packaged Sewage Treatment Plant
Capacity: 4-100 m3/day in Standard Modules
3rd generation Membrane Bio Reactor combining two Proven Technologies:
1) Biological - Enhanced biological treatment incorporating BNR.
2) Physical - Immersed membrane filtration system
Fully Automatic and Totally self – contained, packaged treatment system.
System footprint is significantly smaller than conventional aeration basins because the high biomass concentration enables the use of a much smaller aeration tank and the efficient membrane filtration process eliminates the need for a clarifier. It produces the finest treated water, meeting the most stringent Pollution control norms.
This fully automated system requires minimal operator intervention.
This innovative solution meets the challenges of WasteWater Treatment globally.
| The Challenge | Solutions |
| High load variation (peak / non-peak) | • Adapts to high load variation |
| Space Constraints | • Low footprint – 20-50% lower than conventional systems |
| High-concentration wastewater and stringent discharge regulations | • High quality treated water |
| Capital expenditure | • Need for chlorination/UV for tertiary treatment eliminated • Treatment capacity expansion via existing plant retrofit or staged upgrade |
| High operating costs | • Low power consumption (0.85 KwH/m3) • Reduced cleaning chemicals |
| Odour control | • Continuous aeration eliminates odour completely. |
| Nutrient removal | • Efficient removal of Nitrogen and Phosphorus |
| Manpower / Operator | • Minimal operator intrevention required with advanced control system and maintenance services |
