WASTEWATER BELT FILTER PRESS EC/EM 400 SERIES
The belt filter press comprises an optional pre-dewatering drum and a set of two filter belts that are driven and compressed by a series of rollers. When so required, the sludge is thickened to an ideal consistency by the pre-dewatering drum before feeding it to the filter cloth belts where it is squeezed between the two filter cloth belts by means of a number of compression rollers. In some cases the sludge needs to be pre-treated with a polymer to increase the dewatering properties and to reduce the tendency of the sludge to stick to the filter cloth. The filter cloth belts are automatically cleaned by means of spray nozzles and the dewatered sludge is discharged in the form of a relatively dry ‘cake”.
Features:
- Dewatering of screened solids or sludge
- Receives sludge from clarifier underflow or DAF overflow
- Polymer mixer flocculates the sludge
- Pre-dewatering drum thickens the sludge for inlet consistency below 6%
- Sludge is pressed between two rotating filter belts
- Compaction by pressing rollers
- Dryness controlled by adjustable roller pressure and belt speed
