Net type self-cleaning filter is a kind of precision equipment that uses the filter screen to directly intercept impurities in the water, remove suspended matter and particulate matter, reduce turbidity, purify water quality, reduce system dirt, bacteria and algae, rust, etc., in order to purify water quality and protect the normal work of other equipment in the system.

Water enters the self-cleaning filter body from the water inlet. Because of the intelligent (PLC, PAC) design, the system can automatically identify the degree of impurity deposition, to the blowdown valve signal automatic full blowdown.
1. The self-cleaning filter can only be used according to the rated voltage/frequency marked on the nameplate.
2. Maintain the filter every once in a while. Before cleaning and maintenance, be sure to disconnect the power supply of the self-cleaning filter.
3. Please make sure that the wire plug is not wet during cleaning or it must be dried before reconnecting the power supply.
4. Do not unplug the power cable with wet hands.
5. Self-cleaning filter is only used in indoor aquariums.
6. Do not use the filter if it is damaged, especially the power cable.
7. Please ensure that the self-cleaning filter is working at the correct water level. The filter cannot be used without water.
8. Do not disassemble or repair without permission to avoid danger or damage to the body.
Pretreatment of water filtration refers to the removal or reduction of suspended solids and colloids in water to a certain extent, to meet the general water requirements of the process known as water pretreatment.
The commonly used methods of water filtration pretreatment are as follows:
1. Precipitation
The use of natural precipitation (such as sand settling tank), or pharmaceutical softening (such as the addition of chemical agents), so that the water of sediment, large particles of suspended matter temporary hardness precipitate and settlement.
2. Filtration
The water will be treated through the granular filter material, so that the impurities in the water are intercepted by the filter material to be removed, usually through the common equipment (such as: self-cleaning filter, automatic filter, backwash filter, brush filter) for processing.
3, coagulation and clarification
With the action of coagulant, the solid particles in water can be separated from water by contact and adsorption, changing their size, shape and density
