Diatomaceous Earth (D.E) & Perlite

Get The Most Competitive D.E. Pricing in the Industry

ALAR is one of the largest distributors of Diatomaceous Earth in the United States. We receive bulk pricing from the mills, and those mills are contractually obligated to provide ALAR with the most competitive costs. They cannot sell direct, nor can they match ALAR’s volume discount price.

Should you find a lower cost mill, ALAR will work to get a competitive price. As it stands, ALAR cannot be beat.

Perlite filter media is the alternative to “D.E.” that is a man-made hydrated, naturally occurring volcanic rock with good clarifying power and large throughputs.

“D.E.” is used as a filter precoat for the Auto-Vac®, Flex-O-Star® and Micro-Klean™. “D.E.” comes in a dry powder, but is made down into a slurry feed.


Assortment of ALAR Chemicals

Other ALAR chemicals


Is a unique bentonite clay-based product that absorbs particles while the unique chemical formula acts as a separating agent to encapsulate the solids; removing emulsified oils, ink particles, phosphates, and suspended solids from wastewater. It is not a filter aid media, but a pre-treatment chemical that is added to wastewater prior to filtration. One-Step™ can be utilized on our wastewater systems without modification and can be controlled in pH to minimize chemical consumption.

Dry & Liquid Polymers

Uncoil their molecular chain in order to bridge smaller particles into larger groupings (floc), so that liquid can be released and solids suspended on the filter. Polymers increase flow rates, enhance effluent quality, conserve “D.E.” usage and provide cost savings. ALAR provides a wide range of both anionic and cationic blends used for both coagulation and flocculation of solids.
