Influence of the Precoat Layer on the Filtration Properties and Regeneration Quality of Backwashing Filters

For solid–liquid separation, filter meshes are still used across large areas today, as they offer a cost-effective alternative, for example, compared to membranes. However, particle interaction leads continuous blocking of the pores, which lowers flow rate mesh and reduces its lifetime. This can be remedied by aids. In precoat filtration, these provide an already fully formed cake on fabric, acts surface depth filter. prevents particles separated with thus increases service life mesh. this work, influence layer different fibre lengths cellulose filtration behavior is investigated.
