Press Filter and belt filter

Filtration and dewatering on filter presses and belt filter

The use of  ECOFILTER® in thickening on filter presses and belt filter presses optimizes the capacities of your installation and eliminates clogging of the supporting cloths.


ECOFILTER® improves the preparation of the sludge and increases their dewatering capability by acting as a structuring agent.



– Sewage
– Sludges in following industries :
food – mining and quarrying –  ceramics and paint – carboard – glass – chemicals and tanneries – surface treatment – metallurgie

Ecofilter® as a filter aid, is mixed directly with the sludge to be dewatered, preferably before or during the flocculation or coagulation stage. The mixing is performed at a rate of 5 to 15 % in weight according to the concentration of products to be treated.


–      Improvement in the behaviour of the sludge on the filter cloth.

–      Increase in the pressure and the filtration rate

–      Reduction in sludge creep and less cleaning needed.

–      Improvement in dryness and in the action of the flocculant and/or coagulant.

–      Increase in the agronomic and energy content of the sludge.

–      Overall reduction in the costs of filtration.
