In October 2016 – February 2017 specialists of PRODEKO-EŁK Ltd. manufactured, delivered and installed equipment for mechanical wastewater treatment at WWTP of capacity 10 000 m3/d in Augustów, Poland.
Wastewater treatment plant is located
in south part of Augustów town, about 2 km from city center, and covers an area
of 9 ha. Effluent is discharged into a Netta river. WWTP was built and
commissioned in 1984 as mechanical-biological with sludge regeneration chamber,
primary clarifiers, activated sludge chambers and secondary clarifiers. Treated
wastewater flows to WWTP by sewage system and is delivered by vacuum truck.
Wastewater treatment technology includes mechanical treatment and biological
treatment with activated sludge. The first stage of treatment is process of
mechanical treatment by screens, where larger size wastes are removed.
of screens building, conducted by PRODEKO-EŁK Ltd., was intended to improve of
wastewater treatment quality and automation of mechanical treatment process.
The project at WWTP in Augustów included delivery of following equipment:
Rake screens are intended for extraction of large and medium waste solids from industrial and municipal wastewater with subsequent unloading on a transporter or into a waste container. Screens are made of stainless steel AISI 304, which makes them resistant for corrosion. Special tear drop shaped cross section improves flow characteristics of the filtering mesh and protects from getting stuck of mechanical wastes. Such construction of bars allows to remove wastes easily from the rake, which does not interrupt in further operation.
The waste is fed into the case of the compacting press through the receiving bin and removed by the screw to the washing and pressing zone. Waste is washed from the organic inclusions by pressure water and partly wringed due to the decreasing screw pitch. The squeezed waste is then removed to the receiving bin via the discharge pipe. After compacting, the water is drained between cases into the channel which is located downstream of the screens.
to client’s opinion, PRODEKO-EŁK Ltd. has realized assigned tasks in totally
professional way which emphasizes the fact that the company has great technical
experience in terms of manufacturing equipment for specialistic objects.
