How to choose the type of swimming pool water treatment equipment

"Selection of swimming pool water treatment equipment" At present, there are many kinds of filtration equipment on the market, but there are three main forms, one is pressure equipment, the other is wall-mounted equipment and the other is gravity equipment. The technical characteristics of the three are as follows: 1. Pressure-bearing equipment is usually traditional sand tanks and tanks. The main problems of this equipment are as follows: ① The computer room occupies a large area and the civil construction cost is high. The water treatment room of a standard pond usually needs about 120m2- 150m2; (2) Large power consumption and high operating cost. The power consumption of the main circulating water pump (Q=400 m3/h) of the standard pond water treatment system is usually 30 kW-40 kW; ③ The filter material is too simple. In order to ensure the effluent effect, dosing coagulation equipment must be equipped, which has serious chemical pollution to the water body; ④ There are many valves, low degree of automation and complicated operation; ⑤ The metal material is lined with anti-corrosion lining, which has a short service life; 2. Wall-mounted equipment is equipment that integrates filtration and circulation and hangs on the wall of swimming pool. Without building a machine room and laying pipes, if the outdoor pool is affected by the external environment for a long time, the service life of the equipment will be shortened easily, and the equipment is semi-automatic and manual backwashing, so it is more troublesome to clean and replace the filter bag regularly. Suitable for small swimming pools and private swimming pools, the filtration accuracy is 5- 15NTU, which is not as high as that of gravity equipment. 3. Gravity equipment is a kind of pressureless equipment. In recent years, its market share has increased rapidly, and it is widely used in various swimming venues in China. Its main features are as follows: ① The machine room occupies a small area, and it is combined in three dimensions, and the aeration dissolved oxygen technology is adopted to keep the water fresh and active; (2) Low power consumption and extremely low operating cost. The power consumption of a single main circulating water pump (Q=70 m3/h) in the standard pond water treatment system is usually only 2.2KW ~ 3kw；; (3) The filter material is graded by a filter layer consisting of multiple layers of filter materials, so that the water outlet effect is ensured, and there is no need to be equipped with dosing coagulation equipment, and there is no chemical pollution to the pool water; ④ The equipment has no valve and operation, and the degree of automation is extremely high; ⑤ All plastic material, no replacement parts, and its service life is several times that of pressure-bearing equipment. To sum up, compared with other equipment, gravity equipment has many advantages in technology, operating cost and operation, so it is an ideal choice for many swimming pool water treatment equipment when possible.
