3. What is Belt Filter???
Belt Press Filter or Belt filter press
An industrial machine
Solid/liquidseparation processes
Dewatering of sludges (chemical industry), mining and water
treatment
 Usedin production of apple juice, cider and winemaking

4. How Belt Filter works???
 Before sludge enters the press for dewatering with an emulsion
polymer flocculant that helps form stronger flocs. A transfer
pump will drops the sludge onto a preliminary dewatering
belt (free water molecules separate by gravity and fall into a
collection trough).
 Sludge is conveyed along the belt, ploughs roll it around to help
water drain out. A guide plates will position the sludge towards
the middle of the belt and ensure nothing is squeezed out the
side of the filter. A second gravity thickener will repeats the
process before sludge is fed into a pressing zone.

5. How Belt Filter works???
At the pressing zone, sludge is sandwiched and
squeezed between two belt filters which slowly convey
over and under rollers that force excess water out of the
sludge and through the filter mesh.
Finally, the pressed sludge is scraped off the belt and
collected in a bin. All filtrate and wash water is captured
and transferred back to the front of the wastewater
system for re-processing.

7. Advantages of Belt Filter
 belt filters use relatively lower pressures
 belt filters tend to make less noise and have much quicker startup and
shutdown times
 Belt filters are considered simple and reliable, with good availability, low
staffing, easy maintenance and a long life
 high capacity throughput, as it is designed to handle excess capacity.
 low initial costs
 low energy running costs,
