New spin on textile wastewater treatment

AMSTERDAM – US-based Sea Change Technologies has put a new spin on the clean-up of textile effluent from dyeing and finishing with a new way to treat wastewater and sludge using vortex separation in a one-step process. Funded by Fashion for Good, the North Carolina start-up has recently completed a 3- month pilot-scale trial with Indian textile giant Arvind using its patented cyclonic separation technique to clean wastewater streams and highly concentrated sludge to reduce both chemical discharge and overall greenhouse gas emissions in the dyeing process. Cyclonic separation is a method of removing particulates from an air, gas or liquid stream, without the use of filters, through vortex separation. The work was also supported by apparel retailers Bestseller, PVH and C&A. Reference: https://www.ecotextile.com/2020073026452/dyes-chemicals-news/new-spin-on-textile-wastewater-treatment.html#
