Working principle of Multi-Media Filters with Auto Backwash
The principle is that the larger particles in the water are removed at the top of the water, and the smaller particles are removed in the deeper layer of the filter medium, preventing the filter from blocking too quickly, improving the filtration effect and filtering the flux of the filter water.
It can remove large particles suspended solids in water, thereby reducing the SDI value of water and meeting the requirements of deep purification. The equipment has the characteristics of low cost, low running cost and simple operation. The filter material can be used repeatedly after backwashing, and the service life of the filter material is long.
It is divided into: carbon steel multi-media filter or stainless steel multi-media filter, anticorrosion measures: coating epoxy resin or inner lining natural rubber anticorrosion, water cloth system with hanging basket water, under the dome sheet water, stainless steel pipe type water, flat cloth water, water cloth cap with ABS mushroom type and winding column shaped cloth water, of which pipe cloth Water and dome have a cushion under water, a large cobblestone or large quartz sand, which is mainly due to their large space, resistance, and easy to collect water and backwash.
