How to choose swimming pool water treatment equipment?

"Swimming pool water treatment equipment selection" There are many kinds of filtration equipment on the market at present, but the form of the main three kinds of equipment, one is the pressure type equipment, a wall-mounted equipment, another is gravity equipment. The technical characteristics of the three are as follows: First, pressure-type equipment is usually the traditional sand tank, sand tank, the main problems of this equipment are: ① machine room covers an area of large, high civil engineering costs of a standard pool of water treatment plant room is usually 120m2-150m2 or so; ② large power consumption, high operating costs of a standard pool of water treatment system, the main circulating pumps (Q = 400 m3 / h) of the power consumption is usually 30KW-40kw; ② large power consumption, high operating costs of a standard pool of water treatment system, the main circulating pump (Q = 400 m3 / h) of the power consumption of usually 30KW-40kw; ③ filter material is too simple in order to ensure that the water effect must be equipped with pharmaceutical coagulation equipment, chemical pollution of the water body is more serious; ④ valves, the degree of automation is low, the operation is complex; ⑤ metal materials and anticorrosion lining, the use of short life expectancy; Second, wall-mounted equipment is a set of filtration and circulation in one of the equipment hanging on the wall of the pool. With no need to build a machine room, laying pipes, if the outdoor pool, long-term impact of the external environment, easy to shorten the service life of the equipment, and the equipment is semi-automatic operation, manual backwashing, the need for regular cleaning and replacement of the filter bag, it is more troublesome; suitable for small swimming pools, private swimming pools, the filtration accuracy of 5-15NTU, not as high as gravity equipment precision. Third, gravity equipment is a non-pressurized equipment, the market share has grown very rapidly in recent years, and is commonly used in various domestic swimming pools. Its main features are: ① machine room covers an area of small, three-dimensional combination of aeration and dissolved oxygen technology, to maintain the water quality of fresh activation; ② small power consumption, operating costs are extremely low, a standard pool water treatment system, a single main circulating pump (Q = 70 m3 / h) power consumption is usually only 2.2KW ~ 3kw; ③ filter media graded multi-layer filter media composed of the anti-filtration layer to ensure that the effect of the water at the same time, do not have to Equipped with pharmaceutical coagulation equipment, there is no chemical pollution of the pool water; ④ equipment without valves, no operation, the degree of automation is very high; ⑤ all plastic materials, no replacement parts, service life is several times longer than the pressure-type equipment. In summary, gravity equipment and other equipment, compared to technology, operating costs and operation has many advantages, and therefore in the conditions possible, is the ideal choice for many swimming pool water treatment equipment.
