Love Water… Save Life!
PRESENTATION ON
OUR VISION
To ‘Reduce, Recycle & Reuse’
as much wastewater as feasible from
1) Residential,
2) Commercial,
3) Industrial
sectors in the Middle East
It is the process by which the wastewater from the laundry washers is carefully treated until satisfactory levels of purification for reusing either in the laundry process or other processes as a supplement to the fresh water line supply.
What is Laundry Wastewater (LWW) Recycling ?

Industries benefiting LWW Recycling ?
REVOSIS LWW System proposed for a 5 star Hotel which generates 30,000 Gallons / day [115 m3/d] of Laundry Wastewater . REVOSIS LWW System captures Wastewater discharged from the Laundry room and recycles 90% of it for reuse in their laundry washers.
Assumptions :
Freshwater consumption from local municipality line.
Wastewater disposed off via tankers.
For a continuous operation of 20 hours / day.

ROI Calculation
Case Study Report REVOSIS LWW System recycles and saves 27,000 Gallons of
drinking water a day, over 9.7 million gallons per year per client.
The recycled and treated water from the REVOSIS LWW System is fed in to the fresh water supply Laundry room to supplement the municipality feed line. Hence, reducing fresh water consumption by 85-90 %. Also reducing LWW disposal volume by 85-90%.
LWW is recycled and treated to the highest recycled water standards approved by Local Health Authorities.
Recycled water is successfully reused in the Laundry Washers as a supplement to the municipality line.
Recycled water is reserved for supplementing other areas of municipality feed lines. For eg: District cooling, Irrigation, etc.
REVOSIS turn-key approach includes design, project management, installation, commissioning, operations & service contracts.
5 Key Benefits of Recycling
1) Recycle & Reuse almost 90% of the Laundry Wastewater.
Thereby reducing the freshwater consumption by 90%.
2) Eliminate Laundry Wastewater disposal costs and hassles.
Reduce Laundry Wastewater disposal volume by 90%.
3) Recycled water of better quality (less TDS, TSS) than
available freshwater.
4) Less strain on your ETP.
5) Increase points to reach LEED certification for your
esteemed organization (Go Green).
