Japan's Bio-Lace: Hyderabad's Water Woes Solution?
3 Jul
Summary
- Bio-Lace technology shows up to 90% reduction in BOD.
- System purifies water naturally, without chemicals.
- Requires less land and over 50% less power.
Hyderabad's water board is reviewing Japan's innovative Bio-Lace technology as a promising solution for treating sewage and canal water. A recent pilot project at Fatehnagar, implemented in collaboration with the Japan International Cooperation Agency (JICA) and Euroclean TBR, demonstrated notable improvements in water quality.
The technology, already employed in Japan for river restoration, achieved up to a 90% reduction in biochemical oxygen demand (BOD) and approximately 85% in total suspended solids (TSS). It also enhanced dissolved oxygen levels and reduced foul odours, all without the use of chemicals.
Compared to traditional systems, Bio-Lace requires less land and consumes over 50% less power. This makes it a more cost-effective and environmentally friendly approach to urban wastewater management, potentially playing a key role in preventing untreated sewage from polluting the Musi river.
Encouraged by these results, the Hyderabad Metropolitan Water Supply and Sewerage Board (HMWSSB) is assessing the feasibility of expanding the Bio-Lace system across the city's drainage network. Integration into future infrastructure will be subject to evaluation by the Pollution Control Board.
