The Eliquo Hydrok CWF Storm Flush™ tank cleansing system, also called a 'Flushing Bell', is a cost-effective solution for the removal of sedimentation from storm water storage tanks using an automatic, self-regulated flushing technology.

The cleaning system is non-powered and can be used on all storm water retention tanks. It utilises sewage storm water for the flushing process, thus requiring no additional fresh water.

Operating principle

CWF Storm Flush™ is a simple method for sediment removal. Storm water is held in reserve in the storage reservoir, filled during the tank filling process. At the end of a storm event and after the system has emptied, the retained flushing water is released via the vacuum break within the flushing vessel. This creates a RFP (Roughing, Fine and Polishing) staged flushing regime that mixes and carries the sediment from the base of the tank to the receiving sump.

Construction

CWF Storm Flush™ is made from stainless steel. There are no moving parts within the storm tank. All the necessary valve arrangements are built into a control manifold located in a small manhole chamber located at ground level.

Benefits

  • Cleans ecologically, without external power, external water supply and controls.
  • Flushes even after partial fillings.
  • Fully self priming and flushing operation.
  • Suitable for new tank and existing tank retrofit.
  • Suitable for both open and below ground installations.
  • No moving parts.
  • Intrinsically safe.
  • Any shape tank.
  • Utilises storm water for the flushing process.
  • Retains total volume of storm tank.
  • Final flush polishing stage utilises settled storm water.
  • Synchronised flushing of multi unit installations within larger tanks.
