What is a Backwash Filter?
JX Backwash Filter ——The Self-Cleaning Solution for Industrial Filtration
A backwash filter is an intelligent filtration device that automatically cleans its filter screen through reverse water flow. Widely used in water treatment, chemical, food, and other industries, its core features include "self-cleaning, no disassembly required, and extended lifespan," significantly reducing maintenance costs while ensuring continuous system operation. Below is a detailed breakdown:
1.Working Principle: Three-Step Automatic Cleaning
Forward Filtration
Fluid passes normally through the filter screen, trapping impurities (selectable precision: 5–500 μm).
Differential Pressure Trigger
When the pressure difference across the filter reaches a set value (e.g., 0.5 bar), the system initiates backwash.
Reverse Flushing
Water flows backward to flush the filter screen, discharging contaminants through the drain valve—fully automated, no manual intervention required.
