What is The Automatic Backwash Filter

Automatic Backwash filter is a highly efficient water treatment equipment, mainly used to remove impurities in water to ensure the purity and safety of water quality. The following is a detailed introduction to the backwash filter:

Backwash filters are widely used in industrial, municipal water supply and commercial civil fields, such as thermal power plants, chemical production lines, steel smelters, water plants and sewage treatment plants. It can effectively remove impurities such as silt, rust, microorganisms, colloids, etc. in water to ensure that the water quality reaches high standards.

2. Structure and Working Principle

• The Structure of Automatic Backwash Filter : The backwash filter is mainly composed of a filter cylinder, a filter screen, a drain valve, a drive device and a control system.
• The working principle: The working principle is that during normal filtration, the water to be treated flows into the filter cylinder from the water inlet, the water flows through the filter screen, and the impurities larger than the pores of the filter screen are intercepted, and the purified water flows out from the outlet. As the filtration process progresses, impurities gradually accumulate on the filter surface. When the pressure difference reaches the preset threshold or reaches the set filtration time, the backwash program is automatically activated, the drain valve opens quickly, and a special hydraulic environment is created inside the filter. With the help of the reverse flushing force of the water flow, the filter is driven by the drive device to rotate, shake or translate, so that the impurities attached to it loosen and fall off, and flow through the drain valve to discharge the filter with the sewage.

3. Performance Advantages

• Excellent filtration efficiency: All kinds of impurities are treated equally, whether they are large suspended particles or fine impurities, they can be efficiently filtered out, and the filtration accuracy can reach several microns to tens of microns.
• Highly automated and intelligent: Based on advanced control systems, the equipment can autonomously control the backwash cycle according to parameters such as time and pressure difference, and truly achieve unattended continuous operation. The intelligent monitoring module feeds back the operation data in real time. Once an abnormality is encountered, the alarm mechanism is immediately triggered, which is convenient for operation and maintenance personnel to remotely diagnose and repair in time.
• Stable and uninterrupted water supply: The whole backwash process is cleverly designed to ensure that the purified water supply is uninterrupted. Even during the backwash stage, there is still enough water that has been initially filtered to continue to be output, maintaining stable water pressure and flow in the water system.
