The filter head, also known as the filter cap, is used in the water distribution system and filters of the filter tank. The backwash filter head includes two types: drainage cap and water filter cap, both made of ABS engineering plastic. The structure is reasonable, the connection is firm, the pressure strength is high, the gap does not deform, and the use effect is good. It can prevent the outflow of yin-yang resin and ensure the flow rate. Suitable for filtration equipment such as filter water backwash systems and softened water quality combination, pressure type, loop type, and ion exchangers.
　
The filter cap material is made of ABS engineering plastic, which has high compressive strength and cannot be broken by stepping on it. Strengthen the threads in the filter head structure, add rubber gaskets, connect firmly, and never fall off. The design of the filter head cap base enhances the bottom seam, making it have the advantages of no dead water zone and no mud accumulation between it and the filter plate. Widely used in combination, loop, and ion exchange column equipment for water treatment filters, filtration tanks, and softened water. Various specifications of filter caps are suitable for use in various matched ion exchange columns, activated carbon filters, and also in the drainage system of fast filter tanks.
　
Backwash filter head; The filter head is a backwash device for steam and water in the bottom water distribution system of the filter tank. It can effectively flush out sludge and debris in the filter tank, ensuring the normal operation of water quality and quantity in the filter tank; The types of filter heads include mushroom shaped, plum blossom shaped, tower shaped, and cylindrical shaped, all of which are made of ABS engineering plastic. The structure is reasonable, the connection is firm, the compressive strength is high, the gap is not deformed, and there is no dead water corner area between the filter plates, no mud accumulation, and good effect. Long stem filter heads are commonly used in the backwash water distribution system of filter tanks; Short stem filter heads are used in filtration devices for water treatment equipment such as single water backwashing, gravity type, pressure type filter tanks, and ion exchange filter beds. The filter head and cap are used for advanced purification of urban drinking water and industrial water. The filter head and cap are advanced purification materials used in the production of high-purity water and mineral water. The filter head and cap effectively remove COD, pigments, and toxic substances from water.
