Filtration technology is one of the most important technologies in the water treatment industry and one of the important technologies for oilfield water treatment. At present, there are two types of filtration equipment commonly used in oil fields: gravity filters and pressure filters. Among them, gravity filters are single-valve filters, and there are many types of pressure filters, including quartz sand single-layer filter media filters, double-layer filter media filters composed of quartz sand and magnetite, multi-layer filter media filters composed of anthracite, quartz sand, and magnetite, walnut shell filters, fiber ball filters, etc.

These initiators and additives are easy to decompose and have low efficiency. Some initiators and additives dissolve after decomposition to generate highly corrosive products, which makes the reaction equipment easy to corrode. At the same time, the efficiency of in-situ oxidation regeneration and activation of activated carbon is low, which has a low cost-effectiveness for factory production. Utility Model Content
