Why is it necessary to aerate and to empty the pressure pipe in regular intervals?

The hoelschertechnic-gorator® aera- tion stations oxygenates the waste water when it stays too long in the pressure pipe. Thus they prevent an anaerobic  state and the formation of drain skin and hydrogen sulphide.

What are the components of a hoelschertechnic-gorator® aeration station?

The standard version consists of a compressor for the generation of compressed air and a control cabinet which are both installed in a concrete case. The fittings for the connection from the concrete case to the pressure pipe are installed in the case – easily accessible for assembly and maintenance.

A large range of accessories completes the station and fulfils our customers requirements. As plant manufacturer hoelschertechnic-gorator® offers the possibility of realizing special solutions. Even underground installations – ready for use – including constructional, mechanical and electrical equipment – can be delivered.


The advantages of a hoelschertechnic-gorator® compressed air aeration station

  • waste water aeration prevents anaerobic fermentation
  • sufficient flow speed prevents the formation of drain skin
  • no unpleasant odours caused by hydrogen sulphide
  • the possibility of flushing prevents sedimentation in the pressure pipe
  • reduction of the time the waste water stays in the pressure pipe

The compact solution – submersible pumping station with compressed air aeration station for low flow rates and long distance pressure pipes

The connection of a low pressure drainage with low waste water quantities leads to the well known problems of unpleasant odours and the formation of hydrogen sulphide.

Especially for these applications hoelschertechnic-gorator® GmbH & Co.KG developed the cost efficient and patented solution of an aeration station combined with a pump station.
