Apply to filter air and water backwash water distribution System; the short-handle filter head is used in water distribution filtration systems such as single-water backwashing of filters and gravity and pressure filter tanks and ion exchange filter beds. The filter head can be used not only for domestic drinking water treatment, but also for various industrial water uses such as beverages, printing and dyeing, swimming pools, etc. It can also be used in industrial wastewater and domestic sewage treatment projects.

rb(, , );"> B long-handled special anti-clogging filter head
It is used for water distribution and backwashing of the aerated biological filter (B) Important components. The filter head material is made of imported B engineering plastics. It consists of filter rod, filter cap, embedded casing, etc. It has high pressure-bearing strength and cannot be broken when stepped on. The threads are strengthened in the filter head structure, rubber gaskets are added, and the connections are Firm and never fall off. The base of the filter head cap is designed to enhance the bottom seam so that there is no dead water area and no accumulation of mud between it and the filter plate. The B long-handled special anti-clogging filter head is installed on the filter plate. Its main function is to expose B The bottom water distribution of the gas biological filter and the gas water joint backwashing are even. The B long-handle filter head has a simple structure, reliable process technology, small water head loss, low energy consumption, no dead water area, not easy to block mud accumulation, and construction management. Convenient, the amount of backwash water is only / to / that of a traditional filter, and during backwash the air first enters the bottom of the filter plate in the water distribution area and forms an air cushion layer. When the air cushion layer gradually thickens to the air inlet hole and strip at the lower part of the filter handle When the air inlet gap is formed, a large amount of air enters the filter handle, and rushes out from the gap in the filter head to shear and wash the surface of the filter material particles, causing contaminants to be on the upper part of the filter layer. When water and gas are flushed at the same time, the filter material expands slightly, and appropriate Scrubbing.

Filtration is an important link in the water treatment process. When the filter is running, as the amount of sewage intercepted by the filter material layer increases, the sludge permeability deepens, causing the filtration rate to decrease, and the filter The resistance gradually rises, and the turbidity of the filtered water increases. In order to restore the normal operation of the filter and ensure the quality and quantity of the outlet water, backwashing must be performed at this time. The process of backwashing is to flush the filter plate with air from the bottom of the filter plate. Water enters the bottom of the filter material, and the air inlet flushes the filter material layer on the filter plate. When the filter head is backwashed with air and water, air first enters the bottom surface of the filter plate to form an air cushion layer. When the air cushion layer gradually increases to the long air inlet at the bottom of the filter handle When the hole is opened, a large amount of air enters the filter handle, and rushes out from the gap in the filter head to shear and wash the surface of the filter material particles, causing contamination to be on the upper part of the filter layer. When the water vapor is flushed at the same time, the filter material slightly expands, and is scrubbed appropriately and then Then perform separate water backwashing to backwash the dirt and impurities into the sewage collection tank and drain them away.

B Storage of long-handled filter heads: Filter heads should be stored in a cool place, away from heat sources. Filter heads can be stacked, but they should not be in contact with organic solvents such as ketones, aldehydes, phenols, lipids, hydrocarbons, and acetic acid. , contact with toxic and harmful substances should be prohibited.
B Long-handle filter head operation and maintenance: During operation, the current of the fan and water pump during backwashing should be frequently inspected. If the current is found to be too large, the filter head should first be considered to be clogged. At this time, the operation of the pool should be stopped and the water pump should be drained. Drain the water in the pool, open the manhole, and check whether the anti-clogging facility is blocked by debris. If so, the facility should be removed, rinsed with clean water and then reinstalled.
