Diatomaceous earth Hayward Progrid, details :

Key functions

Filtering with D.E. Hayward Pro-Grid filters is simple, extremely efficient and of incomparable quality (1 to 3 microns of filtering capacity whereas sand filters filter down to 40 - 50 microns) regardless of your swimming pool volume. The tank of the filter is made of corrosion resistant, long lasting Permaglass XL reinforced with fiberglass, of unrivalled lifespan and sturdiness. It results in crystal clean water and it is able to remove even the tiniest particles.

Pro-Grid D.E. filters combine top technology with user-friendliness. (Center clamp securely fastens tank top and bottom together)

Functioning of the diatomaceous earth filters:
The filter is composed of a filtrating refill placed inside the tank.
The filtrating refill consists of several curved vertical filtrating parts called grids.
These elements are composed of septum stretched on a resin coated frame.
These curved vertical grids provide maximum filter service area for greater dirt-trapping capacity and longer periods between cleanings.
Septums are devices upon which the diatomaceous earth powder is collected in its cake structure to form a filtrating screen.
Diatomite is a powdery, non-metallic mineral composed of the fossilized skeletal remains of microscopic aquatic plants called diatoms. To the naked eye, diatomaceous earth is a fine, white powder but under the microscope it is seen to possess certain unique properties of being light, porous, pure, multi-shaped, rigid, inert including property of high absorptivity. All these make it highly desirable as a filter medium.
During backwashing process (cleaning of the filtering element) some of the diatomaceous earth is lost and a refill is needed.

Please make sure you do not discharge used diatomaceous earth filter medium to sewer. Put it into the rubbish.
