RainJets

Overview

Overview

The RainJet is a hydroejector designed to automatically clean tanks used for the temporary storage of stormwater or wastewater so that odour problems are avoided and storage capacity is maintained.

The RainJet continues flushing until the tank is completely empty and all the contents have been pumped into the sewer system. It uses the water already in the tank and hence does not need an external source of fresh water.

The RainJet is made either as a water/water (WW) or water/air (WA) ejector:

  • RainJet WW with greater flow for cleaning wider tanks
  • RainJet WA with jet that reaches further and is mixed with air.

 

The RainJet is made entirely of stainless steel of AISI 304/DIN1.4301 or AISI 316/DIN 1.4401, and is coupled to a wastewater pump of the SE or S type.

Applications

No matter what the size and layout, a customised solution of one or more RainJets can easily be designed to clean detention, equalisation or stormwater tanks used for the storage of excess water in order to minimise the risks of:

  • Flooding or pollution of receiving waters if capacity of the sewer system is exceeded
  • Damage of biological processes at the WWTP if untreated industrial process water arrives
  • Disruption of purification processes at the WWTP due to hydraulic overload.
