Industrial wastes from production processes must be treated within acceptable pollution limits. Depending on the accepted pollution limits and industrial sector of the waste water, biological treatment plants are often not sufficient alone for the treatment of industrial waters. In such cases, the wastewater must be subjected to chemical treatment before biological treatment.
Textile, paper, metal, food industry wastewater of the appropriate solution for the proposed solution is tested in laboratory conditions, the most appropriate treatment process is designed and applied. Chemical wastewater treatment plants, reinforced concrete construction, as well as packaged units are available.
The chemical units consist of fast-slow mixing, plate-settling, sand filtration and backwash pool processes.
