中国沿海供水海水淡化厂

Project Overview

这家海水淡化厂为中国附近的公共设施提供淡水.

The plant combines membrane pretreatment with a two-pass RO process. KC-SW-8040 membrane elements are used in the first-pass SWRO section for primary desalination, followed by a second RO pass and post-treatment before distribution.

RO System Parameters

The first-pass RO system is equipped with 38 pressure vessels, each vessel contains 6 KC-SW-8040 membrane elements, giving 228 elements in total.

The system operates at approximately 11.8 LMH, with a 42% recovery rate, an operating pressure of 5.8–6.4 MPa, and a system salt rejection of approximately 99.6%.

The designed first-pass permeate capacity is approximately 100 m³/h, equivalent to about 2,400 m³/day. The permeate then enters the second-pass RO and post-treatment system.
