SLUDGE handling

MONOBELT® belt filter press

The MONOBELT® belt filter press is an entirely unique patented design. It comprises two units, a pre-thickener and a sludge press. The pre-thickener performs the initial solid/liquid separation stage, taking sludge solids concentration from 0,5-3% up to 5-12% for biological sludge and up to 18% for mineral sludge. The application of an integrated pre-thickener enables dewatering of very low concentrated sludges  (0,5%). Pre-thickeners of this kind are also supplied under the name of SCRUDRAIN® as independent thickeners for sludge thickening, for instance; before digestors.

 

 
The sludge press takes pre-thickened sludge and spreads it uniformly onto the main filter cloth via a series of baffles. Final dewatering occurs as the sludge cake passes between the perforated cylinder, which is covered with secondary cloth, and the main cloth. Discharged sludge cake can reach dry solids contents of 18-30%.
Extensive experience in sludge handling has allowed to produce this innovative belt press which uses an endless belt. Results from existing installations confirm that, as well as producing dryer cake than traditional equipment using the same width of filter cloth, a higher sludge throughput can also be obtained. The use of the endless cloth together with the machine's unique design, allows for rapid and simple maintenance and associated cost reductions. The alignment and tension of the belt are controlled from the main control panel using pneumatic actuators. Sensors monitor the operation of the machine and halt operation in the event of malfunction. The control system provides automatic operation of the sludge pump and chemical dosing equipment.

In keeping with our high standards, the machines are manufactured in 304 stainless steel.

 

Advantages

  • Reduction of operational costs:
   - operation life of endless filter belts is 4 times longer than traditional ones (with metal clips joint)
   - unique possibility of efficient washing by using only filtrate.
  • Reduction of investment costs – belt filter press complete with dynamic drum pre-thickener.
  • Comfortable and safe work – all protection covers and automatic operation.
  • Recognized name and high quality – over 3000 users all over the world.
  • Reliability and easy operation – simply and robust construction.
