STUDY ON FIBROUS COMPOSITES BEHAVIOUR IN HYDRODYNAMIC PROCESS
The porous filtering composites known in the filtration of alimentary liquids as appropriate retention media for fine particulate contaminants are obtained from mixtures of cellulose fibres and mineral particles with different additives. The sheets are formed under dynamic conditions by free and vacuum dewatering and then are dried and finished.

A belt filter press is also known for its high capacity throughput, as it is designed to handle excess capacity. It has low initial costs  and low energy running costs,  however, if throughput is less than 4 million gallons per day, the belt filter press may be less cost efficient than liquid transport, hiring a processing facility, or
Targeting Iron &Manganese in Drinking Water WWD
In greensand beds, the particle breakage that results from air scouring often leads to clogged pores and reduced bed permeability, which reduces throughput over time and shortens the life of the filtration media.

bed filtration the unwanted solids collect or accumulate on the filter septum. These solids lack sufficient permeability to permeate fluid and the filtration proceeds very slowly or terminates. The introduction of a dynamic or continuous filter media changes the composition and the permeability of the accumulated cake.
Ultrafiltration (UF) is a variety of membrane filtration in which forces like pressure or concentration gradients lead to a separation through a semipermeable membrane. Suspended solids and solutes of high molecular weight are retained in the socalled retentate, while water and low molecular weight solutes pass through the membrane in the
