Swimming pool water quality and sanitation implement new national standards
In recent years, with the improvement of people's awareness of health, swimming has become a new fashion trend like running and ball games.
Although swimming is a well-respected healthy sport, in China, due to the secondary pollution of disinfection in many swimming pools, it brings a lot of health risks to swimmers.
On November 21, 2019, at the annual meeting of the China Sporting Goods Industry Federation held in Wuhan, Daisile Technology Group put forward a new concept and a systematic solution on the professional aspects of pool water treatment, and solved it in practical applications. Many questions. At the meeting, the group introduced a system solution called "Dream by Dream Blue Water Purification Technology" to stadium workers from all over the country.
What is different from traditional companies in the industry is that this set of solutions first proposes ideas from the concept: unlike the traditional method, which places water treatment in the most important position, it relies too much on the disinfection of water and the use of disinfectants. . This set of "Dream-Dark Blue Water Purification Technology", a low-chlorine system, takes a different approach, using hydrodynamics to put the scientific design first, and the circulation filtration and backwashing steps are given the highest priority in the design: Correct circulation filtration and backwashing design fundamentally solve the main factors affecting water quality, thereby reducing dependence on disinfectant.
After that, combined with a patented self-purifying active filter material AFM® imported from abroad, the water quality was purified without pollution. AFM® filter material is also an environmentally friendly green material. It crushes brown and green beer bottle glass after recycling, heats it at high temperature, catalyzes it through the surface nanometer, and melts into special biological material to replace the traditional quartz sand. The advantage of this new material is that it is resistant to biological erosion and has a permanent negative charge on the surface. It can have surface catalytic oxidation and can promote the formation of hydroxyl radicals. At the same time, the filter material has a service life of more than 20 years and reduces It has consumed the earth's resources and broken the environment.
"Originally swimming can be a healthy cardiopulmonary exercise, but due to the current problem of water disinfectants, swimming has become a sport that may damage the respiratory system." In all indicators, residual chlorine (including free residual (Chlorine and combined residual chlorine) control is key.
According to Ms. Chen Meixiang, "Residual chlorine is the key to controlling the water quality of swimming pools. Although the new national standard has relaxed the concentration of free residual chlorine to 0.3-1.0mg / L, if the water in the pool cannot be effectively controlled, especially in the filter bed The total number of bacteria, when the free residual chlorine exceeds 0.5PPM, may face excessive levels of combined chlorine. Therefore, we propose the concept of 'low-chlorine swimming pool' and try to control the free residual chlorine between 0.3-0.5mg / L, which is effective protection. The disinfection effect of the pool water, and products that reduce the combined residual chlorine, ensure the health of swimmers. "
High free residual chlorine
Especially the high level of combined chlorine,
Often on the eyes, oral mucosa,
Irritations to the respiratory system, skin, etc.
Residual chlorine concentration is not up to standard
Is caused by many factors,
Therefore, there must be a systematic solution to deal with it;
The main source of urea in water is perspiration in the body
But it does not rule out the public urinating in the pool.
Excessive urea will further increase the amount of ammonia,
This leads to an increase in the combined free chlorine (trichloramine). "
"No matter what kind of water treatment," circulation filtration "and" disinfection "are inseparable. Various disinfection products or disinfection methods have their own advantages, but also have their inevitable side effects, even serious to humans or the environment. hurt."
Ms. Chen Meixiang, an expert in the field of water treatment of the China Sports Goods Industry Federation ’s Venue Business Expert Working Committee and chairman of Daisile Technology Group Co., Ltd. believes that "the spread of microorganisms is a biological phenomenon in itself. Therefore, we must use biological methods. To reduce the spread of microorganisms, to control microorganisms, especially pathogenic microorganisms. For most 'water treatment' systems, filter beds are the main place for microorganisms to breed and multiply, so it is necessary to solve the problem of microorganisms Instead of waiting until the microorganisms have multiplied before using chemical methods to eliminate them. "
The low-chlorine system of the swimming pool can greatly reduce the energy consumption and the dosage of chlorine disinfectant. Without worrying about the potential safety hazards and injuries caused by ozone, you can have better water quality, healthier air, and avoid ozone floating in the air And combined with chlorine, let the water reduce the dependence on disinfection products as much as possible, and exert the self-healing function of the water body as much as possible.
Dream-to-Dark Blue Water Purification Technology-Low-chlorine system uses a patented self-purifying active filter material AFM® imported from abroad. This filter material is crushed brown and green beer bottle glass after recycling. After heating at high temperature, it is catalyzed by the surface nanometer and melted into special biological materials to replace the traditional quartz sand. The advantage of this new material is that it is resistant to biological erosion and has a permanent negative charge on the surface. It can have surface catalytic oxidation and can promote the formation of hydroxyl radicals. At the same time, the filter material has a service life of more than 20 years and reduces It has consumed the earth's resources and broken the environment.
"Dream-Dark Blue Water Purification Technology"-low-chlorine systems can greatly reduce energy consumption and reduce the use of chlorine disinfectants, without having to worry about potential safety hazards and injuries caused by ozone, you can have better water quality and healthier Air, avoid ozone floating in the air above the water surface and combine chlorine, so that the water can reduce the dependence on disinfection products as much as possible, and exert the self-healing function of the water body as much as possible.
How to use the power of technology and biological solutions to reduce the dependence of water bodies on various disinfection technologies as much as possible-just like the vast ocean, using natural ecology and self-purification-this is the "Dream by Deep Blue Water Purification Technology" "The core idea.
