Product Details Supplier Info More products

Flowrox has delivered 20 PV 500 E01 electrically actuated pinch valves to control flow in a Polish wastewater plant being built by Danish engineering company Krüger in Czajka, Warsaw.

Electrically driven mixers rotate at 2RPS in the pools, handling the medium as gently as possible but keeping the waste moving all the time.

The PV 500 EO1 valves control the sludge flow.

Application process

  • After the pools, the water is pumped to the secondary settling tanks.
  • From the surface of the settling tanks, the clean water is lead to a river.
  • From the bottom of the settling tank, a constant flow of biological sludge flows into collection chambers through DN700 stainless pipes.
  • Just before the chambers, the pipes are coned down to DN500 to fit the valves.
  • From the collection chambers, the medium is pumped gently back to the starting point of the process, as the mass contains the cleaning bacteria.
  • The flow is as slow as possible so that the medium is not mixed or treated violently.
