A year later, they started to build stationary treatment facilities using physico-chemical treatment.

Different techniques for wastewater treatment such as: physico-chemical treatment, treatment by electrochemical oxidation and membrane technology were proposed.

However, if chromium containing liquors are isolated from the other processing liquors, sludge collected in a physico-chemical treatment can be used in compost.

With a capacity of about 7.6 million cubic metres per day (two billion U.S. gallons per day), it is the largest primary physico-chemical treatment plant in America.

Physico-Chemical Treatment Processes 40% The CRC has invested well over a $3 million in control systems and instrumentation and developed models which have generated patents.

The commonly used physico-chemical treatment processes are filtration, air stripping, ion exchange, chemical precipitation, chemical oxidation, carbon adsorption, ultrafiltration (UF), reverse osmosis (RO), electrodialysis, volatilization, and gas stripping.
