ARSENSORB®

System Description

Theory of Operation

Pre-Engineered Systems AS series arsenic removal systems are highly flexible, medium to large scale, ion exchange resin based, skid mounted packages. They are designed to remove arsenic from a wide range of potable water feed streams and are easy to install, maintain and operate. Arsenic laden feed water is pumped through two media tanks wich are plumbed in lead/lag series configuration. The tanks are loaded with ARSENSORB® adsoprtion media. ARSENSORB® is an adsorption media consisting of hydrous iron oxide nanoparticles impregnated into a polymer bead and has been developed for the removal of arsenic from drinking water. The small size of the hydrous iron oxide particles and the high porosity of the polymer substrate ensures that the reaction kinetics associated with arsenic uptake is rapid and that arsenic removal capacity is high. The water path is in the down flow direction to minimize channeling and maximize contact time.
