Automatic Micro-Differential Filter For Circulating Water Reuse

Product Overview

The Automatic Micro-Differential Filter for Circulating Water Reuse is an intelligent, high-efficiency filtration system integrating fine filtration, automatic backwash, and smart control. It continuously removes suspended solids and fine impurities from circulating water, ensuring stable water quality and long-term system reliability.

Working Principle

Raw water enters the filter chamber, where impurities are trapped on the filter element surface. Once the differential pressure between inlet and outlet reaches a preset threshold, the automatic micro-differential backwash system activates. Driven by water pressure, the backwash mechanism rotates and cleans each filter element locally, removing contaminants without interrupting filtration.
