Aqua Rejuvenation technology: treating Wastewater for agriculture

In a recent study, it was observed that untreated sewage water is rampantly being used for agriculture, against NGT protocols, which may have adverse health consequences. Recent studies also revealed that the Coronavirus can thrive in Waste Water for over a month.

To remove the water contaminants & to purify the sewage water, CSIR-CMERI developed innovative technology in combination with chemical & physical processes such as

i) mechanical segregation & filtration,

ii) coagulation-flocculation techniques and

iii) chemical/physical adsorption.

Aqua Rejuvenation Plant (ARP) comprehensively treats Waste Water, based upon diverse purification parameters. The CSIR-CMERI developed technology is capable of removing all pollutants from sewage (below W.H.O recommended level) and based upon geographical variations they may be modified. The filter media is also locally source-able so as to ensure that there would not be any stress in the supply chain for scaled-up manufacturing of ARP.

The methods of purification applied by CSIR-CMERI in this technology are 

•  Sedimentation (settlement of flocculated or coagulated particles), 

•  Filtration (process of removing solids from Liquid) and 

•  Aeration (Oxidation and Hydration). 

The Adsorbent media in the filtration components also plays a major role. They are abundantly available naturally and thus are easily source able. 

Benefits:

•  The technology will help in solving in one hand it converts sewage water to potable water which may be used for agricultural purposes thereby conserving the fresh water resources on the other hand it helps to reduce the burden of pollutant enriched grey water converting it into potable one.

•  It is an integrated mechanical and physico-chemical treatment processes based water purification system for effective removal of sewage water contaminants.

•  The technology is economical in terms of maintenance and affordable in terms of operation.

•  Sustainability towards healthy livelihood generation

•  Selective backwash without dismantling any part of the plant; less cumbersome approach.
