Remember the green water of the Rio Olympic Games, which gives people a sense of discomfort. In fact, not only the Olympic Games when such water quality is very difficult to see. But it's not uncommon for pool water to turn green in everyday life.
It is not difficult to find that the pool water turns green as long as there is algae growth in both indoor and outdoor swimming pools. In the management of swimming pool water, the most common problem is that the pool water turns green, which is particularly common in the small swimming pool equipment system. Because there may be imperfect equipment configuration during the investment and construction, although the water of the swimming pool has been sterilized, the water of the swimming pool will still turn green. Shanghai jiehao sauna pool equipment co., LTD reminds you that the main reasons for this result are as follows:
The main reason the water turns green in swimming pools is an overgrowth of algae such as lichens, which are tiny plants but come in hundreds of different types. In the 23 years of swimming pool service at Shanghai jiehao sauna pool equipment co., LTD., algae blooms in the water first consume dissolved carbon dioxide, leading to a rapid rise in pH.
Agent to remove algae in control under the condition of reasonable use, special agent to remove algae in crystal copper sulfate are easily soluble in water, can inhibit the growth of algae in water, and make the water blue, but swimming pool water treatment equipment should not be too frequent use, copper sulfate, belong to heavy metal and chemical products (highly toxic, 500 t of water plus 1 kg of enough, once a week dosing), excessive use of also will pollute water quality.
Shanghai jiehao sauna pool equipment co., LTD suggests that you take a shower before swimming and then enter the pool, which can not only make your body better adapt to the water temperature of the pool, but also avoid water pollution in the courtyard pool.
Normal water is clear and colorless, but improper treatment can cause pool water to turn green. According to the "health standards of swimming places", the residual chlorine in the pool water should be maintained at 0.3-0.5mg/L, and the PH value should be maintained at 7.4-7.6, so that bacteria and algae are not easy to grow and reproduce.
Outdoor swimming pools often don't meet the chlorine standards after a rain, because dilution and acid in the rain can lower the pool's PH, leaving room for bacteria and algae to grow. And when it rains, spores from the air, grass and soil wash into the water, bringing algae with them. Especially in the summer water temperature is relatively high, bacteria and algae will grow quickly, so that the pool of water in a very short time to turn green.
In addition to rainy days, improper water treatment methods may also lead to the greenness of water bodies. For example, if the disinfection dose of swimming pool is not enough, or it is not put in time, it will lead to insufficient edema and residual chlorine, and bacteria and algae will also grow and reproduce, making the water turn green.
