Wastewater treatment in chemical & pharmaceutical industries
In the chemical industry, more and more producers are implementing processes to minimize the water they draw from external sources. This means that less wastewater is discharged and more wastewater is being reused as process water. The wastewater which is generated during the chemical production usually contains materials which are toxic, but also substances which are very difficult to biodegrade. Many conventional wastewater treatment systems are unable to handle such challenging streams.
The production of medicines must also meet the highest standards and protocols, making the quality of process water critical for the pharmaceutical industry. In addition, the high quality of the process water is a requirement for the sterilization of medical devices and storage tanks. Pharmaceutical wastewater streams are characterized by high chemical oxygen demand (COD), variable strengths and peak loads in the amount and concentration of waste.

Kunshan Zhong Yan Company, located in Kunshan City in China’s Jiangsu province, manufactures 600,000 tons of sodium carbonate (also known as “soda ash”) per year. Sodium carbonate serves multiple purposes in both domestic and industrial applications – widely used as a water softener, as a component in the manufacture of glass, a common additive used in swimming pools, and as an ingredient in certain foods, just to name a few.
In order to meet stringent water reuse standards, the Kunshan plant set out to find a cost-effective solution to treat its reverse osmosis (RO) concentrate and improve overall RO system recovery.
