Dicalite's DicaPOOL Perlite Filter Powder is a direct replacement for other diatomaceous earth swimming pool filter powders. As a safe alternative for all Diatomaceous Earth filters, Perlite filter aids can weigh as much as 50% less than the other types of filter media. So 1/2 lb. of Perlite is equal to 1lb. of Diatomaceous Earth, saving pool ...

Perlite filter aids are usable with standard filtration equipment and generally replace other filter aids on a one-to-one volume basis. Perlite filter aids also provide a density advantage from 20 to 50-percent over other types of filter aids—in other words, larger filtration volumes with lower bulk densities.

Perlite is a rock product, and as such, does not decompose at any noticeable rate. Perlite is formed from obsidian rock and water, and is made up mainly of silica. The silicon content of the perlite is generally not accessible by plant roots as perlite is a long-lasting rock product.

Not all Perlite is the SAME. Did you know…Generic Perlite can have HIGH FLOAT. FLOAT is the NON-FUNCTIONAL WASTE that doesn't coat the filter elements and will impact filter performance HIGH FLOAT causes BLEED-THROUGH and SHORT FILTER CYCLES Generic Perlite also tends to have HIGH PERMEABILITY and cannot filter down to 1 Micron.

Perlite is an amorphous mineral consisting of fused sodium potassium aluminium silicate. Dicalite® perlite filter aids are processed at temperatures exceeding 800 °C (1500 °F) which eliminates organic matter. They have extremely low solubility's in mineral and …

Perlite Filter aids are produced in a wide range of grades to economically meet the flow rate and clarity requirements of almost every industry. EASY CAKE RELEASE Because they remain porous and do not compact, perlite filter aids afford easy cake release at the completion of a filtration cycle.

cellulosic filter aid versus diatomite or perlite. Cellulose is combustible and is useful in the recovery of valuble metals. Cellulose is also compatible with hot caustic solutions where diatomacous earth and perlite are not (Cheremisinoff, 1998). S.E.M. Images of …

Perlite's role in filtration of liquids is well documented (and described in detail elsewhere on perlite.org). It plays an important role in municipal and industrial water treatment systems where it is used in conjunction with a rotary vacuum drum filter to remove solids …

Filter Aid. Lightweight and inert, Silbrico Perlite is a natural and cost-effective filter aid that imparts no taste or odor. It provides optimum clarity, variable flow rates, easy cake release and twice as much filtration as diatomaceous earth.

Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian.It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral, suitable "as ceramic flux to lower the sintering temperature", and a commercial product useful for its low density after processing.

Perlites are small pebbles of natural glass which contain a small amount of occluded water, and are found in volcanic deposits. When smashed and softened by heat, the water vaporizes, leaving behind enlarged hollow spheres. These are again smashed, and give a filter aid of very irregularly shaped particles whose bulk density ranges 0.05–0.10 g/mL (3–6 lb/ft 3).
