The bag filter can be normally operated under a certain pressure during the production process, to a certain extent, ensuring that the outlet pressure meets the requirements for the treatment of water quality, and the purified water of the bag filter can be directly delivered to the high water tower. To the extent that the secondary water pumps and supporting facilities required for general water supply projects are saved, investment and operating costs are saved.
Bag filter is effectively based on the characteristics of raw water quality and purification treatment requirements, in the process of use is mainly selected activated carbon, anthracite, homogeneous quartz sand and other composite ratio filter material, the filter effect is good, the water quality is stable.
The connection of the bag filter is small, it is very simple and easy to manage and maintain in the process of operation. The pressure filter is a traditional water purification device in the water treatment industry, widely used, small footprint, easy installation and operation .
The bag filter is mainly used to filter on the surface of the filter medium when it is in use. In the initial stage, the fresh filter medium will make the filtration effect higher or the coarse particles of the suspension first bridge the surface of the filter media to form a filter cake. The layer, while the filtrate with smaller particles flowing away with the filtrate does not clarify the thickening of the filtration layer as the filtration time increases, the tiny particles are captured in the cake layer.
After the filter time increases to a certain extent, the bag filter will clog the flow path of the filter medium and filter the liquid. This will cause the filtration rate of the filter media to decrease. It is known that the flow channel is Completely blocked.
