Quartz sand filter tank design

Quartz sand filter is built in quartz sand filter material, to the sediment in the water, organic matter, such as ion impurities for interception, by backwashing and are washing will be trapped and impurities rinse off, then recycled, with simple operation, low cost, can be repeated use, sewage ability and other characteristics, widely used in water treatment, the attention to introduce the design of the quartz sand filter tank.

quartz sand filter is pressure filters, so must achieve 3 - feed water pressure 4 kg so that he can filter out of the water flow. Filter material selection requirements, the sand filter layer diameter 0. 5 - 1. 2 mm, to ensure the filtering effect, have 1 - pad 2 mm and 3 - 4 mm, mainly is to ensure that the water through, not only reduce the water resistance, but also play a filtering effect.

quartz sand filter tank diameter design according to the processing flow and to determine the design flow, the general design flow velocity at eight 15 m/h, if the water of high content of suspended solids, the design flow rate is relatively slowly, so long run, lower frequency of cleaning, filtering effect is good, such as sewage treatment, water reuse, etc. If the water quality can also originally, such as swimming pool circulating water treatment, water treatment, clean the water processing, the design flow rate can hurry up appropriately, so that the diameter of the quartz sand filter tank, reduced the cost of investment.

quartz sand filter material of tank, generally speaking, there are 304 stainless steel, carbon steel material, general industrial wastewater using carbon steel material, lining rubber processing, and reduce the cost and make the filter tank is durable, and food and water, tap water demanding, such as average of 304 stainless steel material, we generally do not recommend using glass fiber reinforced plastic materials, mainly glass fiber reinforced plastic in and out of the mouth, and it is not convenient for installation, refueling more inconvenient, and easy to aging damage, basic is a one-time use.
