Treating sewage with plants
Posted on 17 Apr, 2018 04:56 PMA radical new method is fast emerging as an effective and sustainable solution to increasing pollution in urban lakes. Called floating treatment wetlands (FTW), they are artificial islands with plants that stay afloat on the lake. The plants clean the lake through hydroponics system, resulting in a cleaner, beautiful lake and an improved habitat for creatures that depend on it.

Tackling fluorosis by following Nalgonda's lead
Posted on 15 Apr, 2018 04:21 PMFluorosis continues to be a regional issue in Telangana to this day, even decades after the first cases were discovered in Nalgonda in 1937. More than three lakh people in the district are affected with skeletal and dental fluorosis, a stigma that has stuck for generations.

Nanomaterial from seaweed can clean toxic water
Posted on 08 Apr, 2018 09:02 PMTreatment of wastewater containing industrial dyes and toxic heavy metals is a major environmental problem as available treatment techniques are not very efficient and environment-friendly. Now a team of Indian scientists has developed a nanomaterial drawn from seaweed for effective treatment of toxic wastewater without using any chemicals.
