Marine Multi-Cartridge Automatic Back Flushing Filter Self Cleaning Filter
Particle contamination in process water accelerates the rate of wear of system components. The particles suspended in the media also have detrimental effects on ends products. In order to protect the operational infrastructure and to guarantee shorter maintenance times, it is essential to have a filtration system to remove solid particles from operating fluids.
The automatic back-flushing filter has been highly useful. Numerous operators of power stations, district heating, sewage treatment plants, and manufacturing plants have relied on this dependable filter for many years.
The fluid to be filtered flows through the filter elements of the back-flushing filter, passing from the inside to the outside. Contamination particles then collect on the inside of the filter elements.
As the level of contamination increases, the differential pressure between the contaminated and clean sides of the filter increases.
1.The gear motor rotates the flushing arm under the filter elements and ensures the contamination is discharged.
2.The contamination is flushed away through the open back-flushing valve.
3.The pressure drop between filtrate side and back-flushing line flushes a small amount of the filtrate back through the contaminated filter elements.
4.The contamination particles collected on the inside of the filter elements are loosened and flushed into the backflushing line via the flushing arm.
5.After the "back-flushing time per element" has expired, the back-flushing valve is closed. In this way, all the filter elements are back-flushed, one after the other.
A back-flushing cycle is terminated once all filter elements have been cleaned.
