Bengaluru: The Centre for Sustainable Technologies’ (CST) researchers at the Indian Institute of Science (IISc) have developed an efficient decentralised wastewater treatment and recycling system at Berambadi primary school in Karnataka.
A new study, published in the Journal of Water Process Engineering and carried out in collaboration with researchers in the UK, shows how the system has, over the past year, enabled the reuse of wastewater and reduced dependence on freshwater resources, IISC release said.
“We have demonstrated for the first time that decentralised wastewater treatment systems can be economically put into practice in a rural setting,” CST Assistant Professor and a senior author of the paper, Lakshminarayana Rao was quoted as saying by news agency PTI.
As per the IISc, the team of researchers operated the greywater treatment system for one year and monitored greywater’s different physicochemical and biological characteristics at entry and exit points.
Approximately 667 litres of greywater were treated on a daily basis using the system, saving around 180,000 litres of water over a year, the release added.
