Better Efficiency for Industrial Sewage Treatment

October 2017 -
September 2020


Policy area:
2. Natural resources 2.1 Clear waters


Industrial waste waters are a considerable challenge for municipal waste water treatment plants as they require special treatment and management. In this project, local water utilities, waste water treatment plants, industrial companies and permitting authorities elaborate and test guidelines and procedures for a more efficient management of industrial sewage.



Problem to be solved

BEST wants to improve the treatment of industrial waste waters. Waste water treatment plants are major point sources of nutrients and hazardous substances entering local waters and the Baltic Sea. The treatment process covers a long sequence of steps easily disturbed if waste waters of abnormal content or amount are discharged to the system without control. Such situations may occur especially concerning industrial waste waters, and cause capacity problems, disturbance of biological treatment processes and pollution of waste water sludge which all lead to increased pollution to the Baltic Sea.



BEST develops more efficient management and co-operation methods among waste water treatment plants, industries and municipalities in order to improve the control of the treatment process. BEST also pilots technical pretreatment solutions that dampen peaks in the industrial waste water discharge to the plant and thus improve treatment. The project further organizes trainings and facilitates exchange of good practices in order to ensure and stress joint learning and transnational cooperation.

Highlights by mid-term:

16 partners representing water utilities, municipal authorities, water work associations, universities and companies from Finland, Estonia, Latvia, Poland and Russia collected information on discharges of industrial waste water, legislation on industrial water management and its implementation. In order to gather the information, the partners cooperated with more than 100 industries in food, dairy, brewery, mining, petroleum, chemicals, surface treatment and waste handling sectors and about 40 waste water treatment plants (WWTPs).

The partners started developing local cooperation models that were tested in municipalities in Poland. Their aim is to improve management of wastewater and cooperation between WWTP, industries, supervising authorities. The partners advanced with the preparations and piloting of technological solutions for better control and treatment of industrial effluents that will be piloted at WWTPs and industries Poland, Estonia and Latvia
