Coagulant powder used to filter sludge from waste water
Environmentalists in Tiruchi had an opportunity on Friday to explore the potential of a truck fitted with mechanical unit to filter waste water in a matter of minutes with the help of patented Japanese technology.
Parked for a few hours on the banks of the Uyyakondan canal near Anna Nagar link road, the mid-size truck fitted with a prototype unit of the Kochi-based company Squas Solutions, has been in Tamil Nadu for over five days. It was invited to Tiruchi by a civic group, Citizens for Uyyakondan (CFU).
