Improved water management system for toxic textile effluents developed
The Hindu
The technology has resulted in the recuperation of 50% of the treatment cost incurred from conventional processes for water treatment
Indian researchers have developed an improved water management system that can completely reuse dye wastewater from textile industries, eliminating its toxicity and making it suitable for domestic and industrial usage, the Department of Science and Technology said on September 9. It can reduce water treatment costs and facilitate reuse of water in dry regions, it added. The current three-stage treatment process for wastewater consisting of primary, secondary, and tertiary treatment is unable to treat toxic industrial wastewater. The stand-alone advanced oxidation process (AOP) treatment technique for colour and odour properties in industrial effluents (dye-based) may be insufficient to meet the set government standards and is also limited due to the high cost of AOPs involving continuous supply of chemical reagents.

How do you create a Christmas tree with crochet? Take notes from crochet artist Sheena Pereira, who co-founded Goa-based Crochet Collective with crocheter Sharmila Majumdar in 2025. Their artwork takes centre stage at the Where We Gather exhibit, which is part of Festivals of Goa, an ongoing exhibition hosted by the Museum of Goa. The collective’s multi-hued, 18-foot crochet Christmas tree has been put together by 25 women from across the State. “I’ve always thought of doing an installation with crochet. So, we thought of doing something throughout the year that would culminate at the year end; something that would resonate with Christmas message — peace, hope, joy, love,” explains Sheena.
