Swimming pool disinfection is a daily work of pool water treatment, and different swimming pools use different methods. The corresponding disinfection technology can be selected according to the swimming pool specifications, the number of users, the level of disinfection requirements, and the economic level. At present, the swimming pool water treatment equipment standards recognized by the Swimming Association are as follows:
Level 1: Metal ion disinfection [Hymatic]
The second level: UV disinfection
The third level: disinfection under ozone
The fourth level: pure chemical disinfection

Why is the metal ion processor a first-level disinfection method? To understand this problem, let's first understand the above-mentioned common swimming pool water treatment and disinfection methods!

Pure chemical disinfection
The method of adding chemical disinfectants is usually a chlorine-based disinfectant. Commonly used chlorine-based disinfectants are: liquid chlorine, calcium hypochlorite (bleaching powder), sodium hypochlorite (high-efficiency bleaching powder, bleaching water), sodium dichloroisocyanurate (euchlorine) Net), trichloroisocyanuric acid (strong chlorine), bromochlorohydantoin (bromine tablets), chlorine dioxide.

Advantages: Contains a certain amount of effective chlorine, strong sterilization, and has a strong ability to continue sterilization, algae, deodorization and deodorization. It is widely used, the technology is relatively mature, and the disinfection system investment and operating costs are low.

All chlorinated chemicals have certain toxicity. Chlorinated organic compounds in water can irritate people's eyes and skin, causing red eyes and skin rashes; corrosive to swimming pool structure, equipment and pipes; high level of operation management requirements, otherwise it will happen In safety accidents, chlorine preparations are dangerous in transportation, storage, and use.

Ozone disinfection
Ozone has the ability to kill all kinds of viruses and bacteria, and it has an excellent effect on degrading various organic poisons, decoloring, deodorizing, deodorizing, and improving water quality. Its mechanism of action is to interfere with its respiratory function by destroying bacteria's dehydrogenase, oxidizing various enzymes and proteins, and destroying the structure of cell membranes to achieve the effect of disinfection.

Advantages: strong oxidizing ability, can remove or reduce the peculiar smell, odor, color and metal ion problems in water, and also help flocculation and reduce turbidity. The sterilization effect is remarkable, the effect is rapid, the sterilization effect is less affected by the water quality, the broad spectrum is high efficiency, and the side effects are small.

Disadvantages: Ozone has poor treatment effects on algae and red nematodes; it has no sustained effect and requires chemical assistance; the equipment cost of ozone disinfection is relatively high, and the power consumption is large. The use of ozone machines is often equipped with oxygen generators, dryers, and exhaust gas. Processor, etc.; ozone is toxic to a certain extent, so be sure to pay attention to safety and dosage when using ozone generators.

UV disinfection
Ultraviolet light is a kind of low-energy electromagnetic radiation that uses ultraviolet light of a specific wavelength to destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial cells, causing growth cell death and/or regenerative cells Death, achieve the effect of sterilization and disinfection.

Advantages: The advantages of ultraviolet disinfection are that the required contact time is short, the sterilization efficiency is high, and the physical and chemical properties of the water are not changed at the same time, and it does not produce odor and other harmful by-products such as methyl halide.

Disadvantages: The raw water turbidity before disinfection is high, and a certain water flow thickness is guaranteed. When the water depth is large, the sterilization effect will be reduced. Ultraviolet disinfection should also use its specific device. Each tube has a limited water treatment capacity and needs Clean and replace regularly.

Metal ion processor [Hymatic]
The ions in the metal ion disinfection technology actually refer to copper ions and silver ions. The electrodes in the metal ion disinfection system generator are subjected to precise low-voltage microcurrents to release copper ions and silver ions, and the excited copper ions and silver ions are positive. Bacteria or micro-organisms in water are generally negatively charged. Therefore, copper and silver ions in the water can interact with bacterial viruses or micro-organisms to cause a flocculation process. The flocculate is cleared out of the pool through the filtration system, thereby achieving the effect of filtration and disinfection. .

Hymatic metal ion disinfection system
The Hymatic metal ion sterilizer is made in Europe and is an honorary product of the European Harvey Testing Instrument Group, focusing on chemical-free swimming pool water disinfection equipment. In 2013, it was introduced by Guangzhou Qianye Water Equipment Co., Ltd. Once it was launched, it was quickly accepted and recognized by customers. In 2017 and 2020, it won the "Product Quality Award" awarded by the China Swimming Pool Hot Spring SPA Industry Conference. Hymatic products have continuously entered the market for many years and are sold to thousands of households.


Hymatic swimming pool disinfection core technology: ABOT special li technology
ABOT technology hydrolyzes to produce strong oxidants such as OH-, O-, O3, H2O2, O2, which instantly kills bacteria, viruses, etc. in the water body; and uses copper-silver ions as an auxiliary sterilization and algae removal. At a specific concentration, copper-silver ions pair Humans are harmless (in fact, people need copper and silver ions to stay healthy).
