Catalyx pilots two-way osmosis system

Catalyx Inc. is developing what it calls a two-way osmosis system to treat difficult wastewater, such as what results from carpet or textile dyeing, which can have high biochemical and chemical oxygen demand. Large amounts of water are often required in carpet and textile manufacturing, and in many other processes. Catalyx's system can purify wastewater streams without chemicals, which are sometimes used in conventional wastewater treatment. Once two-way osmosis is complete, the concentrated, organics-rich wastewater could be used as a feedstock for anaerobic digestion or boiler fuel.
