Seditank Technology

In a Seditank System the effluent discharges into the Seditank by gravity. 

  • The settled grit is removed from the bottom of the grit channel with a horizontal grit screw.

  • An inclined shafted screw then conveys and dewaters the collected grit.

  • The grit discharges down a chute into a grit bin.

Pretreatment

The sludge enters through the Wet Grit Inlet and overflows out of the water outlet. The grit sediments through a screen and forms a sand bedding. A Shafted screw then extracts the washed grit out of the unit.

The Coanda effect by the shape of the Sediwash induces settling of the grit and suspension of the organic matter.

Water is injected to wash the grit and maintain the inlet velocity.

The Effluent flows out of the top of the Sediwash. An organic outlet is available as an option to transfer the organics to a biogas reactor

Our centrifuges were designed with ease of maintenance in mind.  It is one of our greatest strengths. 

Screws

The ​Central Stirrer mechanically scours the grit by making the grit particles abrade against each other and release the organic particles.  The Sedimented Grit forms a sand bedding and passes through the perforated screen

A Sensor measures the sand bedding level and activates the grit extraction screw

Maintenance

Grit bedding recovery and washing is another great application for the Sediwash
