Tri-bore Fiber Membranes could reduce cost of wastewater management

Researchers from the National University of Singapore (NUS) developed a new type of hollow fiber membranes that may potentially reduce toxic waste and associated waste disposal costs.

The thermoplastic fluoropolymer membrane has three hollow cores, allowing for a water flow rate that’s about 30% higher than that achieved by other hollow-fiber membranes.

The membrane will feature in a 5,000-L/day pilot plant – a joint effort between the Separation Technologies Applied Research and Translation (START) Centre, and Memsift Innovations, a local water technology firm specializing in zero-liquid-discharge water treatment systems.

According to the company, the pilot plant will save up to 1.6 million L/year of water and about $184,000 in disposal costs.
