Aqua-Bind® EP
Product Data Sheet


Aqua-Bind® EP is a broad spectrum granular chemical adsorptive medial designed for arsenic, fluoride, and heavy metal removal from water and wastewater. Apyron's Aqua-Bind EP is an enhanced alumina composite that exhibits a wide range of performance in removing arsenic, as well as fluoride, lead, copper, and other metals from potable water, industrial process streams, and groundwater remediation applications. Aqua-Bind EP granular media is ideal for use in conventional Point-of-Use (POU) devices and cartridges, Point-of-Entry (POE) fiberglass tanks, or conventional pressure vessels for adsorption. Regeneration options are available if desired based on the application. Spent media can typically be discarded as non-hazardous solid waste.
