The belt filter, currently considered the world’s most efficient and cheapest in operation, is a device for the removal of slurries from wastewater and simultaneous dewatering of sediment.

Principles of Operation:

The process of removing slurries consists of leaching sludge during transport on a filter net, from which the sludge is discharged into the screw thickener by compressed air. The dehydrated sludge has low humidity (often below 70) which facilitates further disposal.

Equipment:

  • Air blower for blow belt
  • Hot water Washing System

Advantages

  • Reducing the consumption of chemicals compared to Rotositami
  • No servicing, except maintenance only 1-2 hours per week
