Corrosion resistant straight through backwash filter

Corrosion resistant straight through 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.

Corrosion resistant straight through backwash filterApplication advantages

Continuous operation: The backwash process does not interrupt the water supply, ensuring system stability and avoiding production interruptions caused by shutdown cleaning.

Energy saving and environmental protection: using water pressure inside the pipeline to drive backwashing, without the need for additional power sources, reducing energy consumption and operating costs.

Water quality improvement: effectively removes suspended solids and particulate matter from water, reduces turbidity, and protects downstream equipment from blockage and wear.

Strong adaptability: It can treat various media such as industrial wastewater, seawater, and food processing wastewater to meet the needs of different industries.

Extended lifespan: By regularly backwashing to keep the filter clean, equipment wear and tear is reduced, and the overall service life is extended.
