Product Introduction

◎ Product Introduction and Application Fields

　　The SW (SeaWater) series membrane elements are suitable for treating seawater as well as high-concentration brackish water. Their high desalination rate ensures that potable drinking water can be obtained from seawater through a single-stage reverse osmosis process. These elements can be used in a variety of industrial water treatment applications, including seawater desalination, desalination of high-concentration brackish water, and feedwater preparation for power plant boilers. They are also applicable to diverse fields such as wastewater reuse and the concentration and recovery of high-value-added substances like food and pharmaceutical products.
