Purolite (ArsenXnp) Arsenx NP Arsenic and 40 similar items

ArsenXnp is a Nano-particle based selective resin designed to remove arsenic (arsenate and arsenite) from water. ArsenXnp combines a unique chemistry based on hydrous iron oxide nanoparticles that have a very high affinity for arsenic with a durable, non-friable, spherical polymer substrate. This ideal combination of selectivity and substrate durability means that ArsenXnp can effortlessly remove arsenic by using a lead-lag or parallel design configuration. Water treatment systems incorporating ArsenXnp are designed and operated using the same engineering guidelines as conventional ion exchange resins. Superior bead strength means fines will not be generated nor will pressure drop be a concern throughout long-term performance. Bead sphericity also ensures plug flow of the raw water through the bed thereby maximizing the arsenic loading per vessel and complete capacity utilization. ArsenXnp is ideal for municipal water treatment plants as well as point-of-entry (POE) and point of- use (POU) devices.
