How does a precoat filter work?

Rotary vacuum filters: A precoat filter design utilizing a rotating drum onto which a precoat is applied. As the drum rotates through a vat of liquid, the precoat is immersed in the liquid to be filtered. The liquid is sucked up through the precoat and the solids are retained at the surface.

What do cellulose filters do?

Role of cellulose fibrils in filters On HEPA filters, cellulose fibrils could act as a strengthening material, enabling the production of filters with thinner glass fibers, leading to more efficient filters. This would allow to produce even more efficient micro- and ultrafilters for filtering liquid and air.

Is cellulose a filter aid?

Our JELUCEL® cellulose is a filter aid that allows ecological and economical filtration. The cellulose is used in precoat filtration, in combination with mineral filter aids and as a pressing aid. As a precoat and body feed, our cellulose makes up for defects in the filter cloth and improves the filtration result.

Which is the best cellulose for precoat filters?

JELUCEL® filter cellulose is suitable for all designs of precoat filters and is mainly used in connection with the following filter types: Common celluloses for filtration are JELUCEL® HM, a highly purified cellulose, and the technical cellulose JELUCEL® FM.

Where does pre-co floc filter aid come from?

Pre-co-Floc® filter aid is an environmentally friendly filtration alternative made from cellulose fibers. The cellulose fibers are produced from natural, organic, renewable raw materials.

Where does pre-co floc cellulose fiber come from?

The cellulose fibers are produced from natural, organic, renewable raw materials. Pre-co-Floc cellulose fibers can be used independently where silica cannot be tolerated in the system, or together with Celatom ® DE or Celatom perlite filter aids. EP Minerals offers a wide range of cellulose fiber grades to meet all your needs.
