After reading this article you will learn about on-site industrial wastewater treatment.
The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physicochemical processing of synthetic mixture involving operations such as filtration, centrifugation, extraction and/or distillation.
ADVERTISEMENTS:
The wastewater streams, referred to as ‘process waters’ can include mother liquors, washing waters from the purification of products, vapour condensates, quench waters, wastewaters from exhaust air/flue gas clean-up, wastewaters from equipment cleaning and wastewaters from vacuum generation.
Consequently industrial wastewaters can contain a range of contaminant representing the compounds involved at each stage of the chemicals process e.g. unreacted starting materials, intermediate compounds, and unwanted by-products etc. which often constitute the poorly biodegradable content of the total wastewater load.
