Argonide Corporation’s latest advancement in water treatment is their fully functionalized electropositive sorbent. DEAL (diatomaceous earth [DE] with an amorphous coating) exhibits a highly electropositive charge, attracting and capturing sub-micron and other colloidal particles. When incorporated into a carbon block or porous plastic part, it represents the next generation of structured nanofilters. As a result of these electro-adsorptive properties, composite parts incorporating DEAL are capable of treating for virus, bacteria, cysts, chlorine, chloramine, turbidity, heavy metals and other colloidal contaminants. http://www.argonide.com
