The swimming pool equipment wholesale from Fenlin are including about six systems, filter cycle system, lighting system, cleaning system, disinfection system, heating and refrigeration system, and installation system. There full six system make a swimming pool run and keep the water clean, there different size pools have different request for different items like filter, lighting or desinfection items. 

Working principles of wholesale swimming pool equipment

Wholesale swimming pool equipment is a mainstream product choice in the modern pool industry market. With its technical content and design concept, the pool integrated equipment has brought a new impact to the current pool equipment market. Pool integrated equipment is a swimming pool equipment that integrates swimming pool filtration, disinfection and circulation, and has become a mainstream product in the swimming pool equipment market today. In the swimming pool, the main thing to note is whether the water quality in the swimming pool meets the standards and whether it can bring healthy swimming. This is a critical inspection. The water quality in the wholesale swimming pool equipment generally has to be between 7.2 and 7.6. It cannot become alkaline or acidic. Especially in the summer or rainy season, we must pay attention to the appearance of algae and bacteria in order to check regularly that the pool equipment is working properly. There are two kinds of circulation methods most commonly used in wholesale swimming pool equipment. One is downstream and the other is countercurrent. Because the two methods have different technical characteristics, in actual engineering, it is necessary to make the right choice in combination with the use of the pool. The downstream flow adopts the water inflow from the pool wall on both sides of the pool, and the deepwater back in the bottom of the pool is recycled. The specific method is to set the water inlet in the center of the pool wall directly below each lane line on both sides, and set at the deepest end of the bottom of the pool. For some water inlets, the number of inlets is twice the number of lanes, and the number of outlets is equal to the number of lanes. The downstream flow is actually a way of simulating the movement of natural rivers. The treated water pushes the used water, that is, the new water to push the old water into the water treatment equipment, thus avoiding the mixing of new water and old water. The countercurrent type adopts the circulation mode of the bottom water inlet and the water overflowing back to the pool. The specific method is to set a water outlet every 3 meters on the projection line of each lane line at the bottom of the pool, and at the same time, an overflow ditch is arranged on both sides of the pool. In fact, it adopts the method of moving up the water, that is, it advances from the bottom of the pool to the water surface, and finally returns to the water treatment room through the pool overflow tank. Combining the advantages and disadvantages of downstream and counterflow, we can draw the following conclusions: 1. For the star-rated hotels, high-end clubs and Olympic venues with a small number and high grades, the pool water pollution source is small due to the small number of users. The overall water quality uniformity requirement is high, so it is advisable to adopt counter-current circulation. 2. The social wholesale swimming pool equipment with a large number of swimming pools and open to the public. Due to a large number of users, the water content of the pool water is large, and the goal of the water treatment system must be in a cycle. The amount of dirt in the overall swimming pool is rapidly reduced during the cycle. So downstream circulation is preferred.

Solution of excess urea from pool equipment manufacturers

The main pollution of public swimming pools open to the public is organic pollution such as urea, dissolved enzymes and proteins. This kind of situation is particularly prominent in primary and secondary swimming pools according to pool equipment manufacturers. However, conventional pressure sand tanks that cannot remove these pollutions at all. Therefore, it is necessary to add 3%-5% of new water to the pool every day to dilute the concentration of organic pollution. Today, when water resources are becoming increasingly tense, this method must be banned.
In the design of water treatment system, there are two ways to solve the problem of excessive urea: one is to configure ozone equipment in the water treatment system, to produce strong oxidant O3, to fully oxidize the organic pollution in the pool water; the other is to maintain the residual chlorine concentration in the pool water. At the same time, increase the concentration of dissolved oxygen in the pool water, so that the hypochlorous acid in the pool water stimulates the formation of [O] at any time, and oxidizes the organic pollution of the using the strong oxidizing property of [O].
Ozone equipment cannot only remove urea, but also sterilize the pool water, remarked pool equipment manufacturers. The fly in the ointment is the high investment and operation cost of the equipment. In addition, additional equipment such as reaction tanks and adsorption tanks need to be added, which increases the difficulty of daily maintenance.
There are many kinds of filtering equipment on the market, but there are two main forms, one is pressure type equipment and the other is negative pressure equipment. The technical characteristics of the two are as follows:
The pressure equipment is usually a traditional sand tank. The main problems of this equipment are as follows. The machine room has a large area and the civil construction cost is high. The water treatment room of a standard pool usually is about 120m2-150m2 in size. It also requires large power, high operating costs, a standard pool water treatment system main circulating water pump (Q = 400 m3 / h) power consumption is usually 30kW-40kW. Furthermore, its filter material is too simple, in order to ensure the water effect must be equipped with drug coagulation equipment, chemical pollution to water is more serious.
The representative of negative pressure equipment is integrated equipment, said pool equipment manufacturers. In recent years, the market share has grown very rapidly. It has been adopted by dozens of swimming pools in the Guangdong and Guangxi regions. It has main features like machine room, low power consumption, extremely low operating costs are, the power consumption of a single main circulating water pump (Q = 70 m3 / h) in a standard pool water treatment system is usually only 2.2kW~ 3kW. While ensuring the water effect, without the use of drug coagulation equipment, there is no chemical pollution of the pool water.
The principle of chlorine disinfection is that chlorine or chlorine preparations form hypochlorous acid by hydrolysis, and hypochlorous acid is further decomposed to form new ecological oxygen [O]. Strong oxidation of new oxygen denature the bacteria and proteins on the bacteria and other substances, thereby killing the source of the microorganism. Hypochlorous acid can not only act on the cell wall and virus coat in the process of sterilization and virus killing, but also because the hypochlorous acid molecule is small, has no charge, can penetrate into the bacteria (virus), and the bacteria (virus) body protein, An organic polymer such as a nucleic acid or an enzyme undergoes an oxidation reaction to kill pathogenic microorganism. At the same time, chloride ions produced by hypochlorous acid can also significantly change the osmotic pressure of bacteria and virions, causing their cells to lose activity and die.
The disinfectant of the swimming pool must have the following characteristics, suggested by pool equipment manufacturers. First, it does not cause harm to the human body. Second, the disinfection effect is generated quickly. Third, the disinfection effect lasts for a long time. Fourth, the oxidation is large. Fifth, the color and sludge are left in the water. Sixth, drug delivery equipment is safe, convenient, durable, and low in cost.
In comparison, chlorine dioxide does not produce carcinogens during the disinfection process, and the disinfection effect is better, but the investment cost of swimming pool equipment is slightly higher. Therefore, chlorine dioxide disinfection is recommended under conditions.
