Gravity valveless filter
Thread Content
I signed a contract with a foreigner for several gravity valveless filters. The information he requested was relatively detailed. I would like to ask for detailed calculations about the equipment, strength calculations and process calculations. I would be very grateful if the hero has any experience, or any information about the gravity valveless filter.
This kind of valveless filter should be very simple, and it has a molded processing technology.
Advantages of gravity valveless filter: It has no large valves, positive water head filtration, automatic flushing, low cost, and convenient operation and management. Therefore, it has been widely used in railways or small and medium-sized water plants in counties and towns. shortcoming: The water inlet system is complex and the construction requirements are high ； Air is easily trapped during the water inlet process, which affects normal filtration and backwashing. ； Using a single layer of quartz sand filter material, the water production of the filter is low and cannot meet the increasing requirements of water supply.
