A resin trap (or media trap) is a simple, inexpensive protective siev device that ensures the ion exchange resin or other filtration media does not leave the water treatment equipment.
Nalco Water offers resin and media traps that protect water treatment system lines, minimize the risk of downstream contamination and ensure against complete loss of media in the event of a failure.
Many water treatment processes use small granular, plastic, powdered, pelletized and/or crystalline media in a pressure vessel. Over the years, complex screens, slotted pipes, perforated plates and molded devices have been engineered to keep the media in the vessel. But through corrosion, chemical attack, thermal damage, rapid flow changes, system age and/or water hammer, these distribution systems will be damaged.
When the distribution systems are damaged, the ion exchange resin or other media will get into the water distribution system contaminating and/or destroying downstream RO membranes, expensive membrane filters, pumps, tanks, piping, processes and any product touched by this contaminated water.
Best practices call for all media systems to have a resin trap, so you minimize the risk of downstream contamination.
