Under the scorching summer, some wise men saw that everyone was rushing to the crowded and small swimming pool. So they also plan to invest in the construction of the same project in order to share a share of the local market or add a means of attracting customers to their existing business operations. This should be a very correct way of business operation. With the development of society and the improvement of people's material and cultural living standards, swimming pools are becoming more and more popular. But in the eyes of wise men, building a swimming pool is a very simple matter. The big deal is just digging a hole on the ground to put some water. In fact, with the gradual standardization of swimming pool construction, building a standard swimming pool project is a very complicated and tedious task. Now Guangdong Kasdaly Pool Spa Equipment Co., Ltd. is here to introduce and explain, so that more people in the society who want to participate in the construction of swimming pools can have a comprehensive consideration and plan.

Step 1: Selection of swimming pool surface materials:

One is to stick to the surface of the swimming pool with pool bricks according to the original idea. The pool tile swimming pool is shown in the figure below, and the tiles often fall off:

The second is to use adhesive film to paste the surface of the swimming pool. At present, the adhesive film swimming pool has been popular in foreign countries for a long time. It is still in a stage of popularization in mainland China, but we should have reason to believe that in the future, it will be a general trend for the film swimming pool to replace the brick swimming pool with too many advantages and vivid personality. The film film swimming pool is shown in the following figure:

The second step: determine the water circulation mode of the swimming pool: there are three ways of water circulation in the swimming pool;

1. Mixed flow circulation: In this way, all the circulating water of the swimming pool is sent into the swimming pool through the water supply port at the bottom of the swimming pool, and 75%~80% of the circulating water is sent to the overflow next to the outside of the pool wall. The other 20%~25% of the circulating water is taken back from the backwater outlet at the bottom of the swimming pool, and the two parts of the circulating water are combined and sent to the filter to remove impurities in the backwater and reduce the turbidity of the backwater. And after the filtered circulating water is heated, water quality balanced and disinfected, it is sent into the swimming pool from the water supply port at the bottom of the pool to continue to use a water circulation method.

2. Countercurrent circulation: The swimming pool water is sent into the swimming pool through the water supply port at the bottom of the pool, overflows from the pool wall to the return water tank and enters the return pipe, and flows into the equalization pool by gravity, and the circulating water pump absorbs water from the equalization pool and sends it to the filter for removal. Impurities in the water reduce the turbidity of the return water, and after the filtered water is heated, water quality balanced and disinfected, it is a water circulation method that is sent into the swimming pool from the water supply port at the bottom of the pool.

3. Downstream circulation: the entire circulating water volume of the swimming pool is sent into the swimming pool through the water supply port located on the end wall or side wall of the swimming pool, and then sent into the swimming pool through the return water port located at the bottom of the swimming pool through the circulating pump. The filter removes impurities in the backwater, reduces the turbidity of the backwater, and heats the filtered circulating water, balances the water quality and disinfects it, and then sends it back to the swimming pool for continued use.


The third step: choose the circulation system of the swimming pool:

The circulation system of the swimming pool is the choice of the circulating water pump. There are currently four circulating pumps to choose from:

1. Imported frequency conversion pump: with frequency conversion system, supply and demand balance, quiet and energy saving; built-in voltage regulator, safe and reliable operation; built-in overheating and antifreeze system, continuous and stable operation; no water, water shortage detection, instant circuit breaker protection pump .

2. Imported water pump: The water pump has large flow rate, high efficiency and low cost of use. The sound is small, and the efficiency of use is much higher than that of general similar products. Stable operation and durable.

3. Joint venture water pump: high performance, good head, fast cycle efficiency, suitable for large swimming pools and spas. The shell is made of anti-corrosion materials. Imported mechanical seals, bearings, and hair collectors are used to remove debris more easily and have a good heat dissipation effect.

4. Domestic water pump: high-efficiency design of the pump body, guide vane, and impeller structure. The water inlet and outlet of the pump have both inner and outer teeth, which is convenient for connection; the gland and slag basket are easy to disassemble and assemble; the pump flow parts are high-strength engineering Plastic, compact structure; high-quality special mechanical seal, can run continuously for a long time without water leakage; the installation base of the whole pump is high-strength engineering plastic, shockproof and anti-corrosion.

The fourth step: filter system;
There are eight options for the filtration system of the swimming pool, and customers can participate in the selection according to their economic strength:

1. Diatomite filter sand tank: diatomite fiber filter tank with remarkable filtering effect. Fine diatomite forms a filter film on the surface of the filter net, so that the filtration accuracy is high and the water quality is very clean. Diatomite cannot be recycled. In use, it must be disassembled and cleaned once a quarter.

2. Automatic sand tank head: to solve the need to manually clean the sand tank, to automatically detect the pressure and timing control, specify the weekly backwash time, and automatically backwash the sand tank.

3. Stainless steel sand cylinder: the cylinder body is made of AISI304 stainless steel, which is stable in operation, anti-corrosion and durable.

4. Depth filter sand tank: design of micron grade glass fiber reinforced plastic filter sand tank. According to the basic principle of "deep filtration", the impurities in the water enter the tiny gaps between the sand particles with the water flow and are screened there, and the filtering ability is strong.

5. Side-type filter sand tank: the inner liner of the micron-sized FRP sand filter tank is made of glass fiber reinforced polymer resin through blow molding, and the outer shell is reinforced with glass fiber reinforced plastics. The filtration circulation mode is optimal and the operation is convenient.

6. Top-type filter sand cylinder: CNC fiber winding machine is adopted, which can precisely and continuously wind fiberglass fibers, so as to obtain a filter shell with extremely fine texture and extremely strong structure.

7. Integrated filter: a specially designed filter box, inside is a comprehensive filter system. The filter box is made of reinforced plastic and glass fiber, high-quality filter equipment to ensure a balanced filter effect and provide clean and bright pool water.

8. Paper core filter: The cylindrical filter is a compact, economical and durable filtering device. The cylindrical filter is made of specially treated synthetic fibers and pleated to form a filtering area of 2.3 to 14.0 square meters, so that the maximum Maximize the role of the surface area to increase the dirt holding capacity and extend the operating cycle.

Step 5: Sanitize the system:

Swimming pool disinfection is a vital part. Clean swimming pool water brings fitness and sports to people. Swimming pools with poor sanitary conditions will not only fail to bring benefits to operators, but will be supervised and inspected by the epidemic prevention department, closed down, and rectified. There are seven options to choose from:

1. Copper-silver ion water processor: the world's best-selling swimming pool equipment, original in the world, imported from Germany, 100% chemical-free, almost zero operating cost, healthy and environmentally friendly, giving you the most advanced swimming pool enjoyment. The service life of the electrode is more than ten years, and the water can not be changed throughout the year. The product is selected for the International Space Station and the Olympic Games.

2. Ozone disinfection: Ozone has a high rate of killing bacteria, viruses and other microorganisms in water, and the speed is fast. It can completely remove pollutants such as organic compounds without causing secondary pollution. Therefore, drinking water disinfection is the most important performance of ozone application. , the water treatment industry is the largest market for ozone.

3. Ultraviolet sterilization: Ultraviolet sterilization is the use of ultraviolet rays of appropriate wavelengths to destroy the molecular structure of DNA or RNA in microbial cells, causing growth cell death and (or) regenerative cell death, to achieve the effect of sterilization. Using specially designed high-efficiency, high-intensity and long-life UVC band ultraviolet light to irradiate flowing water, directly kill various bacteria, viruses, parasites, algae and other pathogens in the water to achieve the purpose of disinfection. At present, the latest technological product, the ATG medium-pressure ultraviolet light produced in the UK, although traditional chemical disinfection methods are widely used in water supply and sewage treatment, the addition of chemical disinfectants to water will more or less produce harmful disinfection by-products. Therefore, most foreign countries use medium-pressure ultraviolet disinfection for water treatment. 

Ultraviolet disinfection was first used in the United States and is now commonly used in most of the Nordic regions. The effective wavelength range of medium pressure ultraviolet sterilization can be divided into four different bands: UVA (400~315nm), UVB (315~280nm), UVC (280~200nm) and vacuum ultraviolet (200~100nm). Among them, only UVA and UVB parts can reach the earth's surface through the ozone protective layer and clouds. In terms of sterilization speed, UVC is within the range of microbial absorption peaks, and can kill viruses and bacteria by destroying the DNA structure of microorganisms within 1 second, while UVA and UVB are outside the microbial peaks, and the sterilization speed is very slow. It takes several hours to play a bactericidal effect. In the hydraulic retention (irradiation) time of several seconds in the actual project, this part actually belongs to the invalid ultraviolet part. Therefore, the ultraviolet light disinfection mentioned in the water supply and drainage project actually refers to UVC disinfection. Stable and controllable germicidal efficacy of medium-pressure ultraviolet germicidal technology

The power of a single medium-pressure multi-spectrum ultraviolet lamp can reach up to 7300W. Under the same UV irradiation dose of the same processing capacity, the medium-pressure ultraviolet can minimize the number of required lamp systems. The processing capacity of a 3.5KW medium-voltage lamp can be equivalent to 20 low-voltage lamps above 120W, and the quartz sleeve and rectifier matched with the low-voltage lamp (each lamp needs a quartz sleeve and a rectifier, and the service life is generally Less than 1 year), the resulting spare parts replacement costs will also bring great pressure to daily operation and maintenance. And when the number of lamp tubes in the system is relatively large, when the output power of one or several lamp tubes decreases, the low-pressure ultraviolet rays cannot be known at all. Medium-pressure ultraviolet rays can respond to the intensity of the working lamp in time to avoid any accidents that may occur due to insufficient lamp intensity.

4. Salt chlorinator: Salt chlorine electrolysis machine is a device for disinfecting swimming pools by generating chlorine gas through electrolysis of salt. Electrolysis process: the salted water passes through the electrolytic cell, the sodium chloride in the pool water is converted into chlorine gas, and the chlorine gas is dissolved in water and converted into sodium hypochlorite for disinfection.

5. Water quality monitor: Detect water quality, display the current water quality ORP, PH situation, can set the required water quality standard, the detector drives the dosing device to add the corresponding dose of chemicals according to the current water quality.

6. Dosing device: Tablet-type dosing device is a very effective low-cost automatic disinfection device, which avoids the trouble of regularly adding granular chlorine disinfectant to swimming pools or SPA massage pools.

7. Manual: Test the water quality, and add corresponding water treatment drugs according to the deviation of the water quality.

7. Manual: Test the water quality, and add corresponding water treatment drugs according to the deviation of the water quality.

Step 6: Lighting System:

Lighting not only allows swimmers to enjoy the water in the dark, but also adds to the beautiful night scenery of the entire swimming pool
