Longhai indoor swimming pool water treatment technology filtration equipment currently on the market there are many kinds, but there are three main forms, one is a pressure-type device, a wall-mounted device, the other is a gravity device. Technical characteristics of the three as follows: First, pressure equipment is usually traditional sand tank, sand tank, the main problem is the existence of such a device: 1, room area, high construction costs, a standard pool water treatment room usually about 120m2-150m2; 2, power consumption, high operating costs, a standard water treatment system main circulating pump (Q = 400m3 / h) power consumption usually 30KW-40KW; 3, filter too simple, to ensure water effects must be equipped with dosing coagulation equipment, pharmaceutical costs high, and chemical pollution of water bodies is more serious; 4, changing the water 3-5% per day, higher water charges and water exchange costs; 5, valves and more automation low level, complex operation, high labor management costs; 6, plus metal corrosion lining, short life. Second, the wall-mounted device is a filtration cycle in one wall hanging at the pool equipment. Although without the construction of the room, laying pipes, if the outdoor pool, the long-term affected by the external environment, easy to shorten equipment life, and the device is automatically operated, manual backwash filter needs to be replaced regularly, too much trouble; there is no gravity to address water high precision equipment. Third, the gravity device is a non-pressure equipment, in recent years, very rapid growth in market share, is widely used in a variety of domestic swimming venues. Its main features are: 1, room small footprint, low-dimensional type combination, the initial investment costs, financial oxygen aeration technology, keep the water fresh, activation; 2, low power consumption, low running costs, a standard water treatment system power consumption single main circulating pump (Q = 70m3 / h) is usually just 2.2KW-3KW; 3, filter gradation using multi-media filter layer composed of, in effect to ensure water At the same time, not with dosing coagulation equipment, pharmaceutical costs are relatively low, and there is no chemical pollution of water; 4, do not change the water every day just to add a little water can be, changing the water replenishment fees and costs low; 5, the device without valves No operation, high degree of automation, low labor management costs; 6, all plastic material, no replacement parts, service life several times in the pressure equipment.
