Planta desalinizadora de agua de mar para suministro de agua costera en China

Descripción general del proyecto

This seawater desalination plant provides freshwater for nearby public facilities in China.

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.

Parámetros del sistema RO

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

The system operates at approximately 11.8 LMH, con un 42% tasa de recuperación, una presión de funcionamiento de 5.8–6.4 MPa, y un sistema de rechazo de sal de aproximadamente 99.6%.

The designed first-pass permeate capacity is approximately 100 m³/h, equivalente a aproximadamente 2,400 m³/día. The permeate then enters the second-pass RO and post-treatment system.
