What is Diatomaceous Earth?

Aug 02, 2016

Diatomaceous Earth (DE), is an inexpensive natural mineral with honeycomb structure that is ideal for filtering. It is an industrial mineral composed primarily of the skeletal remains of microscopic aquatic plants, called diatoms. Deposits of their skeletal structures accumulated over the millennia, and are now accessible to mining.

Perlite filter media is the alternative to DE that is man-made hydrated, naturally occuring volcanic rock with good clarifying power and large throughputs.

One-Step is an 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 pretreatment chemical that is added to wastewater prior to filtration. One-Step can be utilized on existing systems without modification and can be controlled to pH to minimize chemical consumption.

Dry & Liquid Polymers uncoild their molecular chin in order to bridge smaller particles into larger groupings (floc), so that liquid can be released and solids suspend on the filter. Polymers increase flow rates, enhance effluent quality, conserve DE usage and provide cost savings. ALAR provides a wide range of both anionic and cationic blends used for both coagulation and floccuation of solids.

ALAR is one of the largest distributors of DE in the United States. It is used as a filter precoat for ALAR's wastewater treatment equipment.
