Belt Press


Belt Press

  • Used for solid/liquid separation processes
  • Involve the passing of slurry, sandwiched between filtering cloths and two tensioned belts through a series of rollers
  • Feed could be sludge or slurry, being converted into filtrate and solid cake
  • Designed for thin sludge
  • Operating in relatively lower pressure
  • Resistant to fouling and corrosion

For dewatering municipal surplus sludge to 20-35% dewatered sludge. Particularly efficient for dewatering sludge and other suspensions, the Belt Press carries the slurry between two rotating sieve belts which travel around roughly 14 press rollers of decreasing diameter until the pressure increases to 20 bar, depending on applications. Features of the belt press is that:

  1. Large filter area for pre-thickening
  2. Press cake has the ideal, non-sticky texture for further treatment

The advantages for choosing Belt Press are:

  1. It is possible to achieve very high throughputs, even with thin sludge, by expanding the pre-drainage zones with an extra stage.
  2. Low wear and low-noise operation
  3. Extremely low operating and maintenance costs
  4. Continuous, fully automatic operation
  5. Very easy to operate and maintain

Mostly Belt Press is being used for the sludge produced from:

  1. Municipal and industrial wastewater treatment plants
  2. Paper mills
  3. Steel and rolling mills
  4. Water treatment systems
  5. Sand and gravel
