Bernoulli Backwash Filter
The Bernoulli backwash filter is suitable for various water supply systems, process water systems, and industrial cooling water systems, especially for 24-hour continuous uninterrupted water supply systems. It can remove mechanical impurities from the system to ensure stable operation. Structure and working principle: The Bernoulli backwash filter is mainly made of high-quality carbon steel, with a special stainless steel filter screen, electric actuator, and automatic sewage discharge device. When the filter is working, the electric actuator guides the valve plate to the open position, allowing water to enter the filter from the inlet, pass through the filter screen, and clean water exits from the outlet. When the filter is in backwash mode, the guide butterfly valve is closed, the sewage electric valve is opened, and the entire system can operate normally without shutdown.
Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle. At each suction nozzle, water flows rapidly from outside to inside in reverse, washing impurities attached to the inner wall of the filter screen into the suction nozzle, through the hollow shaft of the suction scanner, then discharged through the drain valve, completing the cleaning process which takes about 30-60 seconds. At this time, the pressure difference returns to normal, the cleaning process ends, and filtration resumes. During cleaning, the system continues to flow.

Product Introduction:
The Bernoulli backwash filter is suitable for various water supply systems, process water systems, and industrial cooling water systems, especially for 24-hour continuous uninterrupted water supply systems. It can remove mechanical impurities in the system to ensure stable operation.
Structure and Working Principle:
The Bernoulli backwash filter is mainly made of high-quality carbon steel, with special stainless steel mesh, electric actuators, and automatic sewage discharge devices. When the filter is working, the electric actuator keeps the guide valve open, allowing water to enter the filter through the inlet, pass through the mesh device, and clean water exits through the outlet. When the filter is in backwash mode, the guide butterfly valve is closed, and the sewage electric valve is opened. The entire system can operate normally without shutdown.
Dirty water enters from the filter inlet, first passing through the coarse filter screen to remove larger particles, then reaching the fine filter screen. During filtration, the fine filter screen gradually accumulates dirt and impurities from the water, forming a filter impurity layer. Because the impurity layer accumulates on the inside of the fine filter screen, a pressure difference forms on the inside and outside of the fine filter screen. When the pressure difference of the self-cleaning filter reaches the preset value, a switch signal is sent to the control box PLC system to start a cleaning cycle. Cleaning process: The cleaning mechanism of the fully automatic negative pressure suction filter is a stainless steel spiral up-and-down moving suction scanner. It is hollow in structure, with several suction nozzles vertically distributed at certain distances along its axis. The inside of the suction scanner communicates with the 3” drain valve. When the drain valve opens, the pressure difference between the internal water pressure of the filter and the external atmospheric pressure generates strong suction at each suction nozzle.
