Perlite is a premium filtration media engineered to replace diatomaceous earth (D.E.) filter media in D.E. (precoat) filters.
Perlite improves filter performance with greater dirt holding capacity resulting in crystal clear water. It is non-toxic and chemically inert, prevents premature fouling on the filter grid, uses less water and reduces maintenance by easier and complete backwashing of the filter media
Advantages of Perlite Over D.E.
Perliteis superior to D.E. in removing dirt and oil contaminants from swimming pools for the following reasons:
Perlite’s higher solids and oil holding capacity results in longer filtration cycles.
Perlite’s lower density allows for a uniform pre coat thickness and deposition on element, resulting in quick and complete backwashing and filter aid regeneration.
