New Filtration System Can Treat Dye Wastewater

Anaheim, CA, Jan. 27, 2009--Catalyx, Inc. has developed a two-way Osmosis system for recycling carpet dyeing wastewater.

The system uses a membrane to employ the forward osmosis concept as is commonly used by plant roots, combined with the more common, reverse osmosis concept.

Carpet and textile dyeing mills are water intensive operations and in many areas there's a shortage of fresh water.

Conventional nanofiltration and/or reverse osmosis equipment requires extensive chemical pre-treatment wastewater to remove the synthetic and natural oils

The Catalyx TWO system can treat the water streams without chemicals, enabling the concentrated wastewater that is rich in organics to be
incinerated in a boiler or anaerobically digested to produce biogas.

Juzer Jangbarwala, Catalyx, Inc. inventor and founder, said, "Our vision is to practice 'subtraction' while treating water, instead of 'addition' of chemicals, as is typically done in the treatment of high organic waste. By concentrating the waste through simple water subtraction, it opens up new possibilities, such as reclaiming the process chemicals and generating biogas from the organics.


"While the eventual goal at Catalyx is to design a system which can utilize this unique membrane for desalination of seawater, we are currently only focused on the system's ability to dewater very difficult to treat wastewater."
