Backwash filter automatically backwash dirt drainage principle, that how the backwash filter is drainage, the following we will introduce.

1、Working filtration: When the backwashing filter is working normally, the water flow steering valve is open. The water to be treated passes through the filter using the principle of inertia and the fine particles of impurities and suspended matter in the water are deposited near the discharge port due to inertia.

2、Rinsing and discharging: When the backwashing filter is flushed normally, the water flow steering valve is open. When the fine particle impurities and suspended matter in the water retained by the screen reach a certain amount, the valve on the discharge port will be opened, that is, the impurities stuck in the collection section of the filter will be flushed out of the action of the water flow until the discharge water is clear. Then close the valve on the discharge port to enter the normal working state.

3、Backwashing discharge: When the backwashing filter is backwashed, the water flow steering valve is closed and the discharge valve is opened, at which time the water is forced to enter the outside of the filter cylinder and the shell sandwich from the mesh hole of the inlet section of the filter cylinder and reverse the impurities adhering to the mesh hole from the outside of the cylinder to achieve the purpose of cleaning the filter. As the steering valve is closed, the flow rate increases after the water passes through the backwash valve and the backwash effect.

Backwashing filter performance and characteristics.

1, The backwashing filter automatically flushes the drainage filter for easy operation and management, high filtration speed, simple and reliable flushing, strong backwashing ability, no power required, and energy saving.

2, flushing drainage can work normally at full flow rate, both to maintain a high flow rate of the system, but also has a very low pressure drop (less than 0.05-0.1m water column) to avoid surface stains caused by the low surface of the flow rate.

3、Backwashing filter saves energy investment and running costs. No high bypass management is required during installation, reducing the investment and installation cost of the three valves in the bypass, and it is installed directly on the pipe network without any support structure, saving space. No disassembly and discharge is required, which reduces labor intensity and avoids disassembly and discharge during commissioning and maintenance, saving labor, effort and time.

Backwashing filter installation, use, maintenance.

1、Thebackwashing filter is installed directly on the product pipeline without any support structure, generally close to the front of the equipment being protected.

2、Flushing can be carried out in two stages. First, the cleaning and discharging stage, open the discharge valve for about 30 seconds, according to the situation of impurities in the pipe set, so that impurities from the discharge port; second, the backwashing stage, the discharge valve is still open, open the water flow steering valve for about 30 seconds, will adhere to the filter on the stay backwashing discharge.

3、No wearing parts for backwashing filter, only regular drainage according to water quality.
