Reverse Osmosis (RO) System For Pure Water Treatment

Product Overview

The RO Membrane Filter for Pure Water Treatment is a high-precision separation system that utilizes semi-permeable membranes to remove most dissolved salts, ions, and impurities from water. It is widely used in the production of high-purity and ultrapure water for industrial and laboratory applications, serving as a core component in modern water purification systems.

Working Principle

Reverse osmosis (RO) operates under high pressure, allowing only water molecules to pass through a semi-permeable membrane while rejecting dissolved salts, heavy metals, bacteria, and other contaminants. The system includes an automatic CIP (Cleaning in Place) process to maintain flux and extend membrane lifespan.

Main Components

• RO membrane elements (spiral wound or hollow fiber)

• High-pressure pump and piping system

• Stainless steel or FRP membrane housing

• Online pressure and conductivity sensors

• Automatic flushing and CIP cleaning unit

• PLC intelligent control panel

Features

• Superior desalination performance: Removes over 99% of dissolved salts and impurities

• Consistent high-quality water: Stable and low conductivity permeate

• Energy-efficient design: Low energy consumption with adjustable recovery rates

• Automatic operation: Integrated flushing, monitoring, and control features

• Easy maintenance: Convenient membrane replacement and CIP cleaning capability

Applications

Ideal for electronics manufacturing, pharmaceutical water systems, laboratories, food & beverage production, boiler feedwater, and other processes requiring high-purity water.

Optional Configurations

• Two-stage RO system (RO + RO)

• Custom membrane and housing materials (PA, PVDF, Stainless Steel, FRP)

• Automatic or semi-automatic control systems

• Online conductivity and flow monitoring

• High-efficiency pump with energy recovery device

• Remote monitoring and data logging capabilities

     Jiangsu Sanhe Environmental Protection Group Co., Ltd., formerly Jiangsu Sanhe Environmental Protection Equipment Co., Ltd., is located on the scenic shores of Lake Taihu. It is a renowned manufacturer and developer of modern environmental protection and water treatment equipment in China. It comprises several subsidiaries, including Jiangsu Sanhe Environmental Engineering Co., Ltd. and Yixing Sanhe Environmental Protection Design Institute Co., Ltd. The parent company has a registered capital of 100.2 million yuan, a building area of ​​over 20,000 square meters, and a staff of 52 technicians. The company boasts not only strong environmental protection equipment production and R&D capabilities, but also a highly qualified team with over 30 years of experience in environmental protection equipment production and service, a passion for environmental protection, and a commitment to integrity.

     After nearly 30 years of continuous effort, our innovative development of new products, technologies, materials, and processes, along with our expertise, has been widely adopted in the industry. We have developed advanced continuous-flow activated carbon filters and differential fully automatic backwash filters specifically for reclaimed water reuse and zero-discharge projects. We have also independently developed high-efficiency activated carbon suitable for flow-through activated carbon towers, resolving challenges in China due to poor adsorption performance, short service life, saturation, and high operating costs, hindering widespread adoption and ensuring long-term effective use of activated carbon.

    ​Since its establishment, Jiangsu Sanhe Environmental Protection Group Co., Ltd. has provided qualified products and services to nearly a thousand renowned domestic and international manufacturers, including municipal sewage treatment plants, the machinery and chemical industry, CNPC, Sinopec, Baosteel Group, Jiangxi Copper Group, Dongfeng Nissan, Dongfeng Motor Corporation, commercial passenger vehicle companies, Hangzhou Luxgen, Great Wall Motors, Dongfeng Peugeot Citroen Automobile, Dongfeng Yangzijiang Bus, CSR Corporation, and the Tarim Oilfield, earning a strong reputation.
