Assessing the current situation (WP2)
In project BEST we produce a description of the current situation of industrial effluents entering municipal waste water treatment plants (WWTP) in the Baltic Sea Region (BSR). We assess the situation in terms of discharges, treatment and management of industrial waste waters by
- describing the most relevant industrial flows, sources and contents of nutrients and hazardous substances and their impact on the waste water treatment processes
- describing existing cooperation practices between municipal WWTPs, industrial companies as well decision making and permitting authorities
- indentifying possible country-specific features: success stories but also bottlenecks impacting on efficient treatment of industrial waste waters at municipal WWTPs
- evaluating the effect of industrial effluents on utilization of sewage sludge in circular economy and nutrient recycling in the BSR
Currently, lack of a coherent understanding about the varying circumstances and capacities around the BSR hinders efficient planning, resourcing, implementation and monitoring of industrial waste water treatment.
- Permitting and regulating environmental authorities need information about existing challenges in implementation of laws regulating treatment of industrial waste water to prevent situations where industrial companies lack incentives to comply with laws and regulations.
- Municipal WWTPs need information about waste water content, fluctuations of industrial effluents to understand their effect on the treatment process.
