Chemicals and Petrochemicals can be defined as a large group of waste water from chemicals, petroleum and natural gas and used for a variety of chemical purposes. Chemicals and Petrochemical plants are in the business of developing substances such as hydrogen, carbon monoxide, synthesis gases, chemicals such as ethylene and its derivatives, benzene and toluene to name a few.
Wastewater treatment in Chemicals and petroleum refineries is a complex process, with demanding environmental management challenges as byproducts can be both volatile and toxic. Petrochemical wastewater often requires a combination of treatment methods to remove oil and other contaminants before discharge. Issues such as groundwater contamination; aromatics; oil, grease and organic removal, and VOC control have to be addressed in order to comply with environmental regulations and maintain a good customer image.
