Wastewater Treatment Plants
Industrial wastewater generated by enterprises of various types requires a differentiated approach to treatment because:
- it has a heterogeneous qualitative and quantitative composition
- it contains varying amounts of organic and inorganic substances with different rates of oxidation
- the substances in the wastewater are present in a dissolved, colloidal, or suspended state
To determine the suitability of wastewater for biological treatment under artificial conditions, the following factors are taken into account: the ratio of organic to inorganic components, the concentration of pollutants as measured by chemical oxygen demand (COD), the presence of the necessary amount of biogenic elements for the normal life activities of activated sludge microorganisms, the pH of the medium, and other factors.
The most common and cost-effective methods of wastewater treatment are biological methods based on aerobic and anaerobic technologies.
