Haljala wastewater treatment plant
Haljala Soojus AS
End of works
The pollution load to the wastewater treatment plant is 22 000 PE and the plant capacity is Qavr=400 m³/d and Qmax=40 m³/h. Approximately 90% of the wastewater comes from the Viru Õlu brewery, one of Estonia’s biggest. New wastewater plant significantly reduces the risk of the treatment system malfunctioning and reduced the pollution load to the Haljala stream and therefore reduces pollution to the Selja River, which is part of a Natura 2000 area. The wastewater treatment plant is also fitted with a remote control system. The wastewater treatment system has Estonia’s first post-filtering function.
