Equivalent Dow Chemical SFD-2860XP Ultrafiltration Modules

Introduction

LEFILTER Ultrafiltration （UF）modules with XP fiber are made from highpermeability, high mechanical strength, hollow fiber PVDFmembranes. Themodules provideexcellent performance, industry leading membraneareawithlow energy andchemical consumption.Thesemodules areanexcellent choiceforsystems with capacities greater than 50 m3/hr(220gpm). TheshorterSFP 2860XP orSFD-2860XP modules arewell suitedforinstallations with limited height. Larger and longer, 8 inch diameterand80inch in length, the SFP-2880XP orSFD-2880XP modules offerahigh effective membraneareacombinedwithhighpermeability that provides the most economical andefficient membranesystem design.

Features

LEFILTER Ultrafiltration modules have the following general properties and characteristics:
*Up to 35% higher permeability than previous generation modules helping to improve operating efficiencies and productivity.
*0.03 µm nominal pore diameter for removal of bacteria, viruses, and particulates including colloids to protect downstream processes such as RO.
*PVDF polymeric hollow fibers for high mechanical strength with excellent chemical resistance providing long membrane life and reliable operation.
*Outside-In flow configuration allowing a wide range of solids in the feed water minimizing the need for pretreatment processes and reducing the backwash volume compared to Inside-Out configurations.
