High Performance Thickener 
Minimum Flocculation requirement

Description

With an increase in thickening difficulty, the conventional gravity thickening method has been replaced with the mechanical thickening method in the preliminary sludge treatment process.
A large number of BDF Decanter installations prove its various advantages: small footprint, high-capacity, easy maintenance and no-odor emission.
In order to achieve a consistent low return-sludge rate in the supernatant treatment process, we developed BDF Thickening Centrifuge. It produces a great result with low centrifugal force and a small amount of flocculant.

Features

  • More than 95% SS recovery with a small centrifugal force and minimum flocculation
  • Removal of phosphorus and odor with inorganic coagulant (polyferric chloride)
  • Consistent sludge concentration: Continuous concentration monitoring system and automatic differential speed control
  • Heavy duty sintered tungsten carbide tiles: Wear-resistive tiles are mounted on the screw conveyor flight with back-up tiles.
  • Automatic cleaning-in-place system: Residue cleaning in the shutdown process and the screw conveyor rinsing in the stationary mode
  • Power regeneration and energy saving: Recovery of electric energy from the backdrive motor
