Explore Xinrui’s water treatment projects for pure water, reverse osmosis, ultrapure water, wastewater treatment, ZLD, reclaimed water reuse, and desalination applications across multiple industries.
June 11, 2026 This project is an ultrapure water purification system built for Ningxia Baoruilong Petrochemical, designed to support stable high-purity water supply for petrochemical production and related industrial processes.
The system adopts a mature multi-stage treatment process, including multi-media filtration, ultrafiltration, two-pass reverse osmosis, and EDI electrodeionization. This process configuration helps remove suspended solids, colloids, particles, dissolved salts, ions, and other impurities step by step, providing reliable ultrapure water for industrial use.
The pretreatment stage uses multi-media filtration to remove suspended solids, sediment, particles, and larger impurities from the feed water. This helps reduce the load on downstream membrane units and protects the long-term operation of the system.
The ultrafiltration system further removes fine particles, colloids, and macromolecular impurities. It provides more stable inlet water quality for the reverse osmosis system and helps reduce membrane fouling risk.
The two-pass reverse osmosis system is used to remove most dissolved salts, heavy metals, ions, bacteria, microorganisms, and organic impurities. Compared with a single-pass RO process, two-pass RO provides higher desalination performance and better water quality stability.
The EDI system performs deep deionization after RO treatment. It continuously removes residual ions without traditional acid and alkali regeneration, helping achieve stable ultrapure water production with lower chemical handling requirements.
This ultrapure water purification project provides a practical process route for petrochemical production facilities that require stable water quality, continuous operation, and reliable system performance.
By combining multi-media filtration, ultrafiltration, two-pass RO, and EDI, the system improves pretreatment stability, membrane protection, desalination performance, and final ultrapure water quality. It is suitable for industrial users who need customized high-purity water treatment systems based on feed water conditions, production capacity, and process requirements.
