What is theory of filtration?

Filtration is a process whereby solid particles present in a suspension are separated from the liquid or gas employing a porous medium, which retains the solids but allows the fluid to pass through. When the proportion of solids in a liquid is less, the term clarification is used.

How does a water filter work?

Water filtration works in one of two ways – physical filtration and chemical filtration. With physical filtration, water is strained, often through a gauze-like membrane, to remove larger particles. With chemical filtration, water is treated with patented smart technology to remove impurities.

What is the basic principle of filtration?

Filtration is a process in which components of a fluid mixture are separated based on their size during the mixture transfer through a porous material. In bioprocess filtration, two modes of operation are commonly employed: (1) normal flow filtration (NFF) and (2) cross-flow filtration (CFF).

What is the science behind water filters?

With carbon block filters, the carbon particles are stationary and every particle is used to maximum effectiveness. A wide range of contaminants is removed from the water — small pollutants are adsorbed by the carbon, while larger impurities are too big to pass through the pores of the block and are left behind.
