Water Reuse Automatic Filtration System High Precision Automatic Water Filter Machine

Automatic Micro-Differential Filter For Circulating Water Reuse

Product Overview

The Automatic Micro-Differential Filter is designed for efficient, fully automatic filtration in circulating water reuse systems. With intelligent differential pressure detection and self-cleaning backwash, it operates 24/7 without manual intervention, effectively removing suspended solids and ensuring stable, clear water quality.

Working Principle

Differential pressure sensors continuously monitor the filter’s condition. When the preset pressure difference is reached, the system automatically initiates the backwash process. The internal cleaning arm rotates under water flow, flushing impurities from the filter elements and discharging them through the drain — all without stopping water supply.

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. We are grateful to all our friends who have given us opportunities and helped us grow!

We firmly believe in down-to-earth and steady development; we advocate scientific innovation and unremitting pursuit; and we promote energy-saving, low-carbon, and green living. We provide our customers with ingenious products and services and strive to establish our company as a leading modern enterprise in China's environmental protection production, research, and development sectors.
