Baoji-Qixin - Sodium Hypochlorite Sterilizer For Swimming Pool

At present, the swimming pool water  sterilization and disinfection treatment mainly includes chlorine disinfection method, hydrogen dioxide method, ozone disinfection method, electrostatic sterilization and algae elimination method, and copper sulfate algae inhibition method. As a classic water treatment disinfection method, hydrogen disinfection method has a history of more than 100 years and is still widely used because of its advantages such as strong disinfection ability, low price, and wide sources. The bactericidal effect of chlorine is mainly due to its strong oxidative properties and easy penetration of cell walls. The main factors affecting the disinfection effect of oxygen are the amount of oxygen added, contact time, pH value, and water temperature.

Turbidity, type and quantity of microorganisms in water. In recent years, people pay more and more attention to safety issues caused by chlorine disinfection. Oxygen disinfectants can also form vaporized amines and dihaloalkane (THM) with urea and organic matter secreted by the human body while killing bacteria and viruses. The volatility of amine oxide can cause special odor in indoor swimming pools, which can irritate human eyes, skin, nose, and mucous membranes.It is confirmed that THM would cause carcinogenic to mice. The U.S. Environmental Protection Agency (EPA) announced in 2001 that THM is harmful to health, saying that long-term drinking of THM-exceeding water may cause cancer in the liver and central nervous system. hazards.

In order to reduce the content of amine oxides and trihalomethanes in swimming pool water and reduce their harm, they can be removed by coagulation sedimentation, activated carbon adsorption and filtration. Using chlorine dioxide or oxygen disinfection method can completely solve the above problems. In the 1940s, some European countries found that chlorine dioxide was effective in water disinfection, but it was not taken seriously because of its complicated manufacture and high price. In recent years, in order to avoid the harmful effects caused by hydrogen disinfection and search for new disinfectants, the research and application of chlorine dioxide are increasing.

Selection of anode

The principle of the electrode method to produce sodium hypooxide is to use diaphragm-free electrolysis to generate sodium hypooxide through a homogeneous secondary chemical reaction. The reaction principle of the anode is to electrolyze the sodium chloride (tablet shape) thrown into the swimming pool. During electrolysis, sodium hypochlorite is formed. The most suitable salt concentration is 3%-5%. The sodium hypochlorite generator used titanium electrode include plate electrodes type and tube electrodes type. The anode material can be coated ballast. The mixed oxide coated anode has a long service life, and the overpotential of this kind of coated anode is relatively low, the efficiency of the chlorine evolution current is higher, and the energy saving effect is better. Our company`s anodes have high efficiency and long service life. It can also be applied to the special working conditions as follows:

• Deoxidation processes (e.g. pickling);
• Electrolyte for high speed operation;
• The electrodes are reversed. In view of the above application conditions, Suzhou Shuertai Co., Ltd. has developed a special anode product that is very suitable for use, so as to achieve the effect of improving the use efficiency of salt and prolonging the service life of the anode.
• main products are as follows:
• Nail metal oxide coated anode;
• Platinum oxide coated bowl anode.

It is found that the carbon dioxide disinfection method has the following advantages:

1. Can reduce the formation of chlorinated by-products such as trihalomethanes in water;
2. When the ammonia content in the water is higher, it will not react with ammonia, and its oxidation and disinfection are not affected;
3. Can kill pathogenic microbes and viruses in water:
4. Disinfection is not affected by water pH
5. After being treated with carbon dioxide, the residual gas in the water is stable and long-lasting, and has a strong ability to prevent re-pollution;
6. Due to the strong oxidation, it can remove the color and taste in water, and does not form aerophenol odor with cool;
7. The removal effect on iron and iron is better than gas.
