1、 A3 carbon steel tanksummary:

A3 carbon steel tank is mainly used for multi-media filters, multimediafilterIt is one of the main equipment for water quality pretreatment, and corresponding design schemes should be adopted according to the water quality to efficiently remove suspended solids, colloids, sediment, clay, humic substances, particulate matter and other impurities in the water, reduce the turbidity of the water, and achieve the purpose of water quality clarification. Its advantages are mainly low equipment cost, low operating cost, and easy management; The filter material can be reused multiple times after backwashing, and the filter material has a long service life; Good filtering effect and small footprint. It is widely used inwater treatmentDuring the process, it is mainly used for water treatment to remove turbidity, reverse osmosis, and ion exchange softeningdemineralization systemPre treatment of surface water and groundwater to remove sediment. The filter materials are refined quartz sand and anthracite coal, etc. The main materials of the equipment are anti-corrosion carbon steel and stainless steel. The inlet turbidity requirement is less than 20 degrees, and the water turbidity can reach below 3 degrees.

2、 Product type and material classification

Multi media filters and mechanical filters can be divided into manual and fully automatic types according to their control types. The manual type mainly controls the operation, forward washing, and backwashing of the filter through valve adjustment; And the fully automatic type is achieved throughFleek or Atuzu automatic noseOr PLC and electric valves can be used to control the operation, forward washing, reverse washing and other states of the filter. According to the tank material, it can be divided into fiberglass tanks, carbon steel tanks, and stainless steel tanks. The inner wall of the tank can be coated with epoxy coating or lined with adhesive for corrosion prevention according to user requirements.

IIIworking principle:

Utilizing the interception and filtration functions of multi-media filter media to remove large particle impurities, concentrated colloids, and suspended solids is a common method, which has the characteristics of low cost, easy operation, maintenance, and management. Its filtration accuracy is between 0.005~0.01um, which can effectively remove colloidal particles and high molecular organic matter; Operating at room temperature, resistant to acid and alkali, oxidizing, with a wide range of pH applications, it can be equipped with a complete protection system and monitoring instruments to achieve dual control of automatic and manual. Commonly used are quartz sand, smokeless coal filter media, magnetite, etc., which have high filtration rate, large interception capacity, and long filtration cycle.
