Product catalog summary
Overview
This document provides detailed information on various types of membrane elements used for water treatment, including CPA, ESPA, LFC, ESNA, and SWC membranes. These membranes are designed for different applications such as desalination, wastewater treatment, and ultrapure water production.

CPA (Composite Polyamide) Membranes
CPA membranes are known for their high rejection rates of 99.7% and are used in applications like desalting well waters and producing ultrapure water for semiconductor manufacturing. They are available in 4” and 8” configurations.

ESPA (Energy Saving Polyamide) Membranes
ESPA membranes offer high flux at lower pressures, providing cost savings in operational expenses. They achieve up to 99.6% nominal rejection and are used in municipal and industrial applications.

LFC (Low Fouling Composite) Membranes
LFC membranes are designed to reduce fouling rates and improve efficiency. They offer 99.7% nominal rejection and are suitable for challenging feedwaters that require significant pretreatment.

ESNA (Energy Saving Nanofiltration) Membranes
ESNA membranes provide 50% - 91% salt rejection at ultra-low pressures, making them ideal for softening applications and removing organics. They are used in municipal water treatment.

SWC (Seawater Membranes)
SWC membranes are designed for seawater desalination, offering high salt rejection and reliable performance across varying salinities. They are available in multiple configurations to suit different needs.

IMSDesign Software
IMSDesign is a software tool for designing integrated membrane systems, available for download or on CD.
