Water treatment purposes
Artificial swimming pool water in the pool and pipeline system at a certain rate of circulation, due to swimmer, air and supplementary water into the organic and inorganic pollution, the pool of water may have the following problems:
First, the growth of bacteria
The amount of bacteria in the raw water is usually in the range of a few to several tens of milliliters per liter, but in a swimming pool where the temperature is adequate, the nutrient source is sufficient and the atmosphere is fully exposed, the bacteria can breed five to ten times per milliliter in three to five hours (Or even more), which contains a certain amount of the body into the pathogen.
Second, water turbidity
Water turbidity is a lot of aspects, water impurities, organic matter content is the main reason.
Third, the water causes irritation to the skin, eyes and hair
As the pool of water PH, alkalinity inappropriate, or the accumulation of organic pollutants, the human body surface and even the respiratory tract to stimulate
Fourth, the water color change
Normal swimming pool should be microstrip blue clear water, but the raw water into the metal ions and the growth of algae in the pool water will cause the water discoloration
Fifth, pool water blistering
Accumulation of organic matter or insufficient water may cause foam in the water
These factors cause the water quality problems, it will affect the swimmer’s physical health and sensory comfort, even leads to different degrees of infection swimmers, such as cough, dermatitis, fever, asthma and even more serious infectious diseases.
