This biotech startup's wastewater treatment solution can solve India's water crisis - here is how

This Mumbai startup has successfully treated more than five 5 million litres of wastewater and industrial effluents from textiles, chemicals, and pharma industries.

We’re told three-fourths of the Earth’s surface is made up of water. Yet, an acute water crisis has befallen us, with even large metropolitan cities from Cape Town to Sao Paulo having gone dry for days together. Closer home, India is said to be facing its “worst water crisis in history”.

A June 2018 study by NITI Aayog found that nearly 600 million Indians are under “extreme water stress” and about 200,000 people die annually due to lack of access to clean potable water. NITI Aayog warns the crisis is only going to “get worse, and 21 Indian cities are likely to run out of groundwater by 2020".

It is therefore imperative to not only conserve water but also process wastewater and make it fit for reuse. And, INDRA Water, a Mumbai-based water recycling startup, is doing just that.

INDRA Water’s core solution

INDRA has developed a portable electrocoagulation-based system to treat industrial effluent and wastewater from textiles, chemicals, and pharma industries, and sewage from residential, commercial, and municipal establishments. Electrocoagulation involves the passing of electricity through pollutants and contaminants to break their chemical bonds. This technique is considered to be more effective than a simple chemical filtration.

Besides the hardware, INDRA has also developed a smart software system, which runs on machine learning algorithms and predicts how a water stream will behave when passed through the device. The entire water processing can be automated and/or remote-controlled through this system.

Since its commercial launch six months ago, INDRA has successfully treated more than five million litres of wastewater and says it is on........
