Проект предварительной очистки воды высокой чистоты для завода электроники в Китае

Project Overview

This project was built for an electronics manufacturing plant in China, where stable RO permeate quality was required as feed water for the downstream high-purity water system.

Using municipal water as the feed source, the plant adopted a complete pretreatment and RO desalination process to support continuous production water demand. The main RO section uses KC-BW-ZM8040 membrane elements to deliver stable low-conductivity permeate for further polishing treatment.

RO System Parameters

The first-pass RO system uses KC-BW-ZM8040 membrane elements and is arranged in a 12:6 two-stage array. Each pressure vessel is loaded with 6 мембранные элементы, for a total of 108 elements.

The system is designed at approximately 18.0 LMH, with a recovery rate of about 75%. Operating pressure is typically 0.85–1.05 MPa, and overall system salt rejection is maintained at ≥99.4%. The first-pass RO permeate capacity is about 72 m³/h, with product water conductivity typically controlled at <8 μS/cm.
