Filtration Aid
CAS Number: 61790-53-2
Filtration aids are mineral or polymeric additives used to improve the efficiency of liquid-solid separation in pressure filters, vacuum filters, and gravity filtration systems. They include diatomaceous earth (DE), perlite, and polyelectrolyte filter aids that build a permeable filter cake or precoat for faster filtration and clearer filtrate. They are widely used in drinking water, swimming pool, beverage, and industrial filtration.
