Ecodex® precoat products are homogeneous mixtures that combine inert microfine fibers with two powdered ion exchange resins: strongly acidic Powdex® cation and strongly basic Powdex anion resins. A patented process permanently bonds Powdex resins with fibers to form durable flocked agglomerates. Similar to Powdex products, the fine particles and floc structure provide a large surface area that efficiently filters suspended solids. The electrokinetic nature of the Ecodex precoat attracts and adsorbs colloids and color bodies. The fibrous component maintains precoat integrity and prevents cracking that may otherwise occur as suspended solids loading increases. Ecodex delivers revolutionary features and benefits in easy-to-use formulations.
