General description

The Progard® S2 Pretreatment Pack is designed to pretreat water by removing large particles, organic compounds and free chlorine from tap water. This protects the reverse osmosis (RO) membrane against mineral scaling, organic fouling and chlorine oxidation.
Progard® S2 Pretreatment Pack ensures that your system lifetime and performance are optimized.
Replacement of consumables when requested by the system is key to maintain the system′s performance within specifications.
Designed for use with Direct-Q®, Elix® and RiOs™ 5/8/16 water purification systems.

Application

Removal of organics, free chlorine and particles from tap water to protect the RO membrane.

Features and Benefits

  • The Progard® S2 pretreatment pack is constructed from polypropylene and EPDM.
  • Suitable for tap water feed with silt density index (SDI) < 12, Cl2 < 3 ppm and TOC < 2000 ppb.
  • Natural activated carbon media exhibits a high surface area and adsorption kinetic, tolerating feed water containing up to 3 ppm of chlorine and 2000 ppb of TOC.
  • To prevent the bacteria proliferation, the natural activated carbon selected has been impregnated with silver, a proven bacteriostatic agent.
  • Depth filter media exhibits a high capacity and optimized retention, tolerating feed water with SDI up to 12.
  • Incorporates polyphosphate, specifically selected to avoid scaling without releasing ions.
