Desalinated water membrane and ion exchange treatment process

Membrane and ion exchange technology is currently one of the advanced water treatment processes in the world. Based on different water quality and requirements, Ba'an Water can provide engineering services for ultrafiltration (UF), reverse osmosis (RO), and electrodeionization (EDI) treatment systems and ion exchange systems. Membrane and ion exchange technology are currently the two main treatment technologies widely used in desalination water treatment processes. The design of desalination water treatment process is generally based on different inlet water quality and outlet requirements. Ba'an Water will tailor an economical and reliable desalination process plan for customers based on different requirements for raw water quality and effluent water quality. Membrane treatment technology is one of the advanced and widely used water treatment processes in the world, including ultrafiltration, reverse osmosis, electrodeionization, and ion exchange technology. Ba'an Water has many years of rich experience in these technologies and has successfully applied them to multiple water and sewage treatment projects. The characteristics of ultrafiltration (UF) technology are stable effluent quality; The effluent quality is stable, and SDI meets the requirements for reverse osmosis inflow; Low voltage operation, low energy consumption; Can effectively remove colloidal silica; The removal rate of bacteria and viruses is greater than 99%; Small footprint and high degree of automation. The characteristics of reverse osmosis (RO) technology include the use of imported high-quality products for key equipment such as membrane elements, pressure vessels, and high-pressure pumps; High desalination rate; Stable water production; Easy to operate; High degree of automation. Electrodeionization (EDI) technology has been introduced by Ba'an Water to produce deionized water using modular treatment units from abroad. This technology combines ion exchange and electrodialysis membranes to remove ions from water. Due to its high influence and expertise, the company has become one of the developers of the national standard for "Electrodeionization Pure Water Preparation Equipment". The characteristics of Electrodeionization (EDI) technology are high and stable water quality; The desalination rate reaches 99%; Low energy consumption; Easy to operate, safe, fully automatic operation, no need for dedicated supervision; No need for chemical agents to regenerate resin, no downtime due to resin regeneration, and no generation of acidic or alkaline wastewater; Stackable design, small footprint. Ion exchange technology utilizes ion exchange resins to exchange anions (or cations) in water with hydroxide ions OH - (or H+) in the resin of the ion exchange column as the solution passes through the column, thereby removing impurities from the water and achieving desalination. Ba'an Water can provide corresponding ion exchange technologies based on the inlet water quality and outlet water quality requirements provided by customers, such as traditional boiler feedwater primary desalination and mixed bed treatment systems, circulating cooling water weak acid treatment systems, and coal chemical condensate treatment systems. At the same time, Ba'an Water can carry out general contracting design, installation and commissioning, including process pipelines, valves, equipment, instruments and electrical control.
