Direct backwash filterIt mainly consists of a shell, a filtering unit, and a water flow guide valve. It is recommended to install it on a right angled bend, and the automatic backwash sewage filter should be installed horizontally or vertically. When installed vertically, the water flow direction should be from top to bottom for the straight through type. During installation, attention should be paid to the direction of the arrow on the outside, which must be consistent with the direction of the water flow.
Direct backwash filterStructure and Working Principle
It is mainly composed of high-quality carbon steel (or stainless steel) cylinder, special structured stainless steel wedge-shaped filter screen, butterfly valve, and sewage equipment. When the filter is working, the butterfly valve is in the open state, and the water flow enters the filter from the inlet, passes through the filter screen, and is filtered to the outlet. When the filter needs to discharge water, close the butterfly valve and open the discharge valve. The water flows through the first half of the filter screen, and some of the water flows into the system through the outlet. The remaining water flows from the outer side of the second half of the filter screen into the inner side and is discharged through the discharge outlet, playing a role in reverse automatic flushing of the filter screen. The entire flushing process system can work normally without stopping the machine.
Application field
Industrial water treatment: Filtration of cooling water in industries such as steel, chemical, and power to prevent equipment scaling and corrosion.
Municipal water supply: Pre treatment of drinking water to remove suspended solids and ensure water quality safety.
Agricultural irrigation: Filter impurities in irrigation water, avoid nozzle blockage, and improve irrigation efficiency.
Commercial buildings: Central air conditioning circulating water filtration to protect equipment operation and extend service life.
Environmental protection field: Pre treatment of sewage treatment plants to reduce subsequent process loads and improve treatment efficiency.
