Poxifil Underdrain System is an inert, non-porus underdrain system used to support filter or ion exchange media in a vessel. Poxifil is cast on-site to produce a flat-bottom underdrain for make-up or condensate polishing applications. Poxifil is an aggregate of sand, gravel and a proprietary epoxy material, a stainless steel or plastic header-lateral system encased in epoxy, with stainless steel well screen stainers installed above the PoxiFil material. A flat or slightly sloped surface is created to fill voids and enhance resin transfer.

Pretreatment Site Survey Service to provide a thorough understanding of the operational status of the installed pretreatment system; determine it's efficiency, and offer priortized recommendations to optimize and improve the existing equipment to achieve the desired results and reduce operating costs.
