Comparison of water treatment methods for swimming pool water treatment

In today's international swimming pool water treatment methods are varied, but mainly in China are diatomite filtration, quartz sand filtration, and auto-detonation dissolved oxygen filtration.
First, diatomite filtration
1. Diatomaceous earth filter should be used for diatomite filtration, and natural filtration material (diatomite) should be used as filter medium;
2. High precision turbidity <0.1NTU, which belongs to slow fine filter, can effectively filter suspended matter, colloids, algae, and sound animal insects in water;
3, short recoil time, backwash strength is small, can save water and electricity;
4. The equipment occupies a small area and the equipment is of low height, which is suitable for installation and use of swimming pools of various floors.
5, use life of up to 20 years.
Second, quartz sand filter
1. The filter medium is mainly quartz sand;
2, the cost-effective equipment;
3, equipment operation after many years of use to verify, stable operation, long service life;
4. The filtration rate is medium-speed filtration, and the filtration accuracy can meet international standards. When the flow of people is high, the quality standard can still be reached.
5, filter material can be recycled, filter sand tank material using environmentally friendly, high-quality glass fiber and reinforced polyester synthesis, corrosion resistance, pressure resistance, less than 8 years of service life;
Disadvantages:
1, long rinse time.
2. The filtration accuracy is more different than diatomite.
3, the equipment covers an area of large.
4, long running time, high operating costs.
Third, automatic explosion of dissolved oxygen filter
1. Some domestic equipment manufacturers mainly push products, adopt gravity-type detonation and then filter the way, there are 7 layers of natural filter material, filtration accuracy is high.
2, no pressure gravity design, no power filtration, saving electricity.
3, no valve, no replacement, no maintenance, save manpower.
4, siphon principle automatic backwash technology.
Disadvantages:
1. This technology originated in Europe and entered the international market for more than ten years, but it has not been used in international and domestic large-scale game-specific venues (Olympic Games, Asian Games, World Swimming Championships, etc.). It has not been incorporated into the Design Rules for Water Supply and Drainage in Swimming Pools and Water Amusement Pools. There is no mention in the professional map set. The technology has yet to be validated.
