fully automatic back wash disc fiter

High filtration precision, small area, flexible assembly of multi- unit, and large flow filtrationFilter organic matter: for example, carbonaceous organic matter dissolved in water, protein of fish and shrimp carcasses, seeds and algae.Filtration of inorganic matter: such as silt, clay, sediment, etcSuitable for filtration of various water qualities, such as tap water, well water, surface water, circulating cooling water, etc.If the backwash pressure cannot be guaranteed by the outlet water pressure, external backpressure equipment can be used to achieve backwashWhen the filter is in the filtering state, the turbid water is filtered through the disc from the outside. The disc are tightly squeezed together by the force of spring and water. The foreign particles are trapped at the intersection of the disc, and the filtered purified water flows out of the filter

When a certain pressure differential is reached, or the system automatically enters the backwashing state within a set time, the controller controls the valve to change the direction of the water flow, and the disc is released by the filter water pressure, and the nozzle located in the center of the filter is sprayed along the tangent line, then the disc is rotated, impurities and particles are washed down from the disc small groove and discharged through a Drainage pipe. The filter disc is compressed again and enters the filtering state.
