Water Recycling and Reuse
Recycling and reuse augurs well for the environment as well as for industries. By setting up reuse and recycling systems, the limited freshwater supply can be better prioritised. With focus on municipal industrial tie ups, cash-strapped municipalities will stand to gain from reuse by means of water purchase agreements.
WABAG’s offerings are based on the conviction that “Water is too precious to be used just once”. The company has numerous standout references that employ advanced multi barrier systems and testify to its expertise in the domain of water reuse.
Testifying to WABAG’s pivotal position in the context of water reuse is the plant executed by WABAG at Windhoek, Namibia in 2002. The capacity of the reclamation plant totals 21,000 3/d and the raw water used consists of treated municipal wastewater. The key process steps are: Oxidation and Pre-ozonation, Powdered Activated Carbon Dosing, Coagulation and Flocculation, Dissolved Air Flotation (DAF), Dual Media Filtration, Main Ozonation, Biological Activated Carbon Filtration (BAC), Ultrafiltration, Disinfection and Stabilisation. Since start-up, all the relevant standards have been fulfilled without difficulty for over 15 years in operation.
The company’s recycling capabilities are highly pronounced in the industrial sector too. In India alone, WABAG has about 20 industrial water recycle-and-reuse projects to its credit. The water reclamation plants for Oil & Gas majors like Indian Oil Corporation and Reliance Industries are marquee references in this regard.
