This is how the AWS Flush Trough works:

Strong soilings and deposits remain on the floor of a retention basin after each storage event.AWS-Flush Troughs are installed elevated in basins or channels and are filled for flushing after the basin is filled with water or wastewater. When completely full the Flush Trough tipps automatically and drains the charge vertically. After redirection into a horizontal direction the flushwater creates a strong flush surge over the flush way/ basin floor. Deposits are directed to the pump sump. From the pump sump contaminants are pumped back into the sewer.

The form of the AWS-Flush Trough has been developed using finite element modelling (FEM). Through FEM modells the optimal material load has been developed and the amount of material used has been minimized. Therefore, the weight has been optimized. The AWS-Flush Trough is the state of the art of the international market.

Benefits:

• Very low energy requirement (ca. 0,3 - 0,5 kWh per tipping action)
• Minimal maintenance
• No aeration equipment necessary for parallel filling of up to three flush troughs
• Light weight through optimal material usage
• Corrosion resistant material
• Entire structure is floodable
• Tested and approved by the German technology institute TUEV
• Filling with combined sewage, sanitary sewage, stormwater,groundwater, potable water
• Freely selectable operational parameters with HST control technology (timer controlled, amount of flushes, quiet night hours, etc.)

Special features:

• Floodable bearings made of Nirocast
• Ideal moment and stress diagramms, thus low strain and optimal load of the structure
• No mechanical noises
• High life expactancy
• Coupling of multiple AWS Flush Troughes possible
• Hytronic-kit for automated operational control
• Integrated remote control technology i.e. HST-Telematic technology, HydroDat, KANiO easily possible

Applications:

• Retension- and Detension basins
• Storage sewers
• Industrial and commercial surface areas
• Closed conduits
