Investments at WWTPs and industries (WP4)

Project BEST demonstrates how cooperation between local and regional stakeholders and the implementation of most suitable technological solutions result in better process control and treatment of industrial effluents, and thus, reduces the load of nutrients and hazardous substances in outgoing waste waters. 

Altogether five project partners will invest in new solutions for industrial waste water treatment. The investing partners include both municipal waste water treatment plants (WWTP) and dairy industries:

1) Leszno water utility (WWTP Henrykowo) in Poland is investing in a pilot-scale fermentation installation

The investment demonstrates optimal utilization of industrial sewage and sludge for energy production. Leszno water utility will evaluate the potential benefits and challenges of utilizing effluents from meat processing industries, stockyards and growing industrial zones containing heavy metals and other harmful substances from the point of view of sludge utilization for energy production.

2) Doruchów Commune in Poland is investing in phosphorus filtering system enabeling nutrient recovery for industrial waste waters

Doruchów Commune will  separate treatment of industrial and municipal wastewater and build a new treatment line for industrial wastewater treatment. The investment includes a pilot on phosphorous removal based on an innovative filter media technology (Polonite), which removes phosphorus without any chemicals and enables full phosphorous recovery from waste water.

3) Põltsamaa waste water treatment plant in Estonia invests in analysing equipment for monitoring industrial effluents

Adequate monitoring of indusrial effluents ensure sufficient capacity of the WWTP during high flows of industrial effluents. Põltsamaa waste water treatment plant is receiving wastewaters with high biological oxygen demand (BOD) and nutrient contents from food production industry and dairy production of E-Piim company.

4) E-Piim cheese factory in Estonia invests in a regulation tank for pre-treatment of effluents

E-Piim has already established pretreatment facilities in forms of a flocculation process but to optimize the treatment process at municipal Põltsamaa WWTP, effluent flows should be further regulated.

5) Latvijas Piens cheese factory is investing in process control and flotation facilities

At Latvijas Piens pre-treatment and better process control of BOD and nutrient load are needed to enhance the treatment results at Jelgavas Udens municipal WWTP.

Why?

Wastewaters from food and dairy production have high organic (BOD) and nutrient pollution content, and furthermore, the amount of sewage depends on production processes and can fluctuate significantly, which causes capacity problems for receiving municipal WWTPs. Technical solutions for pre-treatment and regulation are often rather simple and cost-efficient. In the BEST project, the technical solutions developed and implemented jointly by municipalities and industries will demonstrate case-examples that ensure both efficient treatment and recycling of nutrients at the municipalities receiving wastewaters from food and dairy production.

Although the challenges in treatment of industrial effluents are related to techniques, another equally important aspect is the institutional practices: joint planning, communication and cooperation between industrial, water utility and municipal parties as well as local or regional permitting authorities. The project activities will demonstrate in practice how, in addition to well-planned and cost-effective technical investments, development of better management and cooperation between stakeholders plays a key role in improved treatment of effluents
