Organic wastewater (COD/BOD) treatment

A treatment method that combines the characteristics of biological treatment and chemical treatment.

Our company conducts primary treatment through biological treatment methods or coagulation and sedimentation after necessary pretreatment for high concentration and high load COD processing, followed by chemical oxidation treatment on the effluent. We reduce the pollution load within the range that can be treated by biological treatment, which has low running costs, thereby controlling the total running costs. In cases where it is possible to generate poorly soluble organic substances, coagulation and sedimentation may be used instead of biological treatment. 【Features】 ■ Chemical treatment is performed in the later stage to reduce COD concentration to meet discharge standards. ■ Finishing is done with chemical treatment, which is expected to provide stable operation compared to biological treatment. ■ Suitable for wastewater that is difficult to meet discharge standards with biological treatment alone or wastewater that does not operate stably with biological treatment. ■ In the event of temporary trouble with biological treatment, treatment is carried out solely with chemical treatment to cover until the biological treatment is restored. *For more details, please refer to the PDF materials or feel free to contact us.
