In projects involving groundwater salinization, industrial tailwater reuse, and water supply in remote Northwest China, brackish water reverse osmosis desalination technology is currently the most mature and widely used method. Brackish water differs from ordinary surface water and high-salinity seawater, with a total dissolved solids (TDS) content ranging from 1000 to 10000 mg/L. Its complex composition, susceptibility to scaling, and high levels of colloidal impurities make it highly susceptible to problems such as membrane element fouling, decreased desalination rates, soaring energy consumption, and frequent equipment shutdowns if reverse osmosis system parameters are not properly matched.
Water Treatment Equipment
DIEN Water Treatment has been deeply involved in the brackish water desalination field for many years. Based on extensive experience from numerous implemented projects, it has systematically broken down and standardized the core parameters of reverse osmosis desalination to address the characteristics of brackish water. This helps project selection and maintenance personnel accurately control equipment operation, ensuring the long-term stable, efficient, and low-cost operation of brackish water reverse osmosis systems.
I. Overview of the Core Principles of Brackish Water Reverse Osmosis Technology
Compared to seawater reverse osmosis, brackish water reverse osmosis operates at lower pressure, has a higher membrane flux, and lower maintenance costs; compared to ordinary pure water reverse osmosis, it has higher requirements for parameters such as resistance to scaling, fouling, and osmotic pressure.
Core Performance Parameters of Reverse Osmosis Membranes: The reverse osmosis membrane is the core carrier of brackish water reverse osmosis desalination technology. Membrane performance parameters directly determine the final product water quality. DIEN Water Treatment's entire equipment system uses highly fouling-resistant brackish water-specific membrane elements, and core parameters are standardized and meet standards.
II. Common Problems and Optimization Solutions for Abnormal Core Parameters
Continuously Decreasing Desalination Rate: This is mostly caused by membrane fouling, membrane aging, and insufficient operating pressure. Optimization Solution: Inspect the pretreatment system, strictly control SDI and turbidity; fine-tune the operating pressure; perform regular chemical cleaning, and replace aging membranes promptly.
