Disc filter for liquid / solid separation
Polytech
Stacked disc depth filters provide superb filtration for the most demanding filtration applications. Polytech designed filter systems utilizing this filtration technology as an alternative to diatomaceous earth precoat filter systems that have historically been used in these applications. Filtration well under one micron is available in a simple, low cost package that avoids the complexity of precoat and backflushable extended life media systems and the mess of manual precoat filters while eliminating workplace concerns about airborne silica.
Stacked disc depth filters utilize technologically advanced gradient density depth filter media of fully bonded cellulose fiber and diatomaceous earth. The fibers are laid down so that the openings decrease in size from the entry to exit surface capturing ever finer particles as the liquid passes through the media. The crystaline structure of the diatomeceous earth provides a high void volume for dirt holding capacity
