HMWSSB tests Japan’s Bio-Lace tech to clean city drains
The Hyderabad Metropolitan Water Supply and Sewerage Board has launched a pilot project to purify city drains and water bodies using Japan’s Bio-Lace technology. Officials said the method, being tried for the first time in India, has shown significant improvement in water quality.
Hyderabad: A pilot project to purify nalas, open drains and water bodies using Japan’s advanced Bio-Lace technology has been initiated by the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB).
On Friday, HMWSSB Managing Director K Ashok Reddy, along with representatives of Japan International Cooperation Agency (JICA) and Japan-based TBR organisation reviewed the performance of a 1-MLD capacity Sewage Plant at Neemkar Nagar in Sanath Nagar.
HMWSSB officials said Bio-Lace technology which was used to restore more than 400 rivers and waterways in Japan, was being used for the first time in the country to purify flowing polluted nala (drain) water.
Ashok Reddy said tests conducted as part of the pilot project indicated a significant improvement in water quality and that the technology could serve as an effective and environment-friendly solution for pollution control in urban nalas.
Compared with conventional sewage treatment plants, Bio-Lace technology offered more than 50% power savings, 70–85% less land requirement, treatment through natural microorganisms without the use of chemicals, and lower maintenance costs.
