Industrial companies are increasingly facing problems with the management and disposal of contaminated water. In recent years, due to increasing public pressure and stricter legal regulation, this issue has become increasingly relevant. For this reason, it is worthwhile to discuss the importance of industrial wastewater treatment for industrial companies.
Industrial wastewater is typically quite contaminated and characterized by high concentrations of suspended solids, organic and chemical pollutants (BOD/COD), total nitrogen and phosphorus (TN/TP), heavy metals, and various other environmentally hazardous chemical substances.
In practically all cases, industrial wastewater cannot be discharged directly into municipal sewage networks or biological treatment plants without preliminary treatment.
Typically, primary physical-chemical wastewater treatment is applied to industrial wastewater. Primary wastewater treatment is carried out by flotation, filtration, or sedimentation, most often using special chemical reagents, which in each case must be selected by determining their types and effective doses.
During primary wastewater treatment, only pollutants in the form of suspended solids and metals are separated from wastewater, while dissolved pollutants in wastewater remain unremoved. Together with suspended solids, wastewater pollution is correspondingly reduced according to other parameters—BOD, COD, fats, partially phosphorus, nitrogen, respectively only to the extent that the values of these parameters constitute suspended solids. Pollutants in dissolved form must be removed from wastewater in biological treatment plants.
