The pool water treatment system is a system for handling impurities (dirt, bacteria, cosmetics, and oil and sweat secreted by the body) in swimming pool water. The impurities in the pool water are mainly dirt, bacteria, cosmetics and oil and sweat secreted by the body, as well as debris, dust, leaves and bacteria and algae that are grown in the pool. Most of these impurities are insoluble in water, because of their different proportions floating to the surface of the water, some mixed in the water, some precipitation to the bottom of the water.
The floating and sinking of impurities is a process and time interval, and the speed of upand and sinking is affected by the specific gravity, but also by the water flow. If the water surface and bottom of the water are installed swimming pool water cycle filtration backwater system and the water return system can water proportion less than 1 kg / l and equal to 1 kg / l impurities inhalation cycle filtration system, at the same time, the water backwater system can be the proportion of water greater than 1 kg / l and equal to 1 kg / l of impurities inhalation cycle filtration system.
In this way, only the surface and underwater impurities need to be treated simultaneously. If the pool water does not have a backwater system on the surface of the water for circulation flow, then the pool surface is the dead water area, if the pool water at the bottom of the pool does not circulate flow filtration, then the bottom of the pool is the dead water area.
After the treatment of the pool water into the pool to feed water, the cloth water is required to be uniform, no dead zone, no short flow. Water feed method has the bottom vertical water to water and the pool wall horizontal water two kinds, water return method is also two kinds: the dropr and bottom drain back water, the overflow sink and bottom drain back water. By arranging the combination of 2 x 2 water feed and backwater, we can get 4 kinds of swimming pool water circulation methods, which are used in foreign countries, they are: a. Best recycling method:
(1) the bottom of the pool vertical water feed, overflow sink and bottom drainback water system. b. The most common lying method:
(2) the pool wall level water, aoid and bottom drain back water system. c. Available recycling methods:
(3) vertical water feed at the bottom of the pool, apen-dropr and bottomed drainback system.
(4) Pool wall level water, overflow sink and bottom drain back water system. Conclusion: The scientific way of swimming pool water circulation is to ensure that all pollutants with different proportions flow through the circulation filtration system, and then intercept, layer and remove. If the water surface of the pool does not circulate, the water surface is the dead water area, if the bottom of the pool is not circulating flow, the bottom of the pool is the dead water area. The two cases of dead water on the surface and dead water at the bottom of the pool occur in our flow-through cycle and counter-flow cycle, which is a situation to be avoided abroad.
