The selection of pump types in many water feature projects is currently aimed at saving building space or reducing project costs.

The selection of pump types in many water feature projects currently opts for submersible pumps that do not require a pump room, in order to save building space or reduce project costs. However, the reliability of submersible pumps in China (including some foreign submersible pumps) is significantly lower than that of dry centrifugal pumps. The consequences of individual submersible pump failures are twofold: first, the water feature often exhibits local defects and incomplete shapes; second, if the insulation of the pump is damaged, it can lead to electrification of the water body, and there have been several incidents in the country where electric leakage from landscape submersible pumps has resulted in casualties. If centrifugal pumps are used, it increases the length of the pipeline and necessitates the establishment of a pump room, which significantly raises the cost of the water feature.

Creating new highlights for the dreamlike water scenery stage.

Creating new highlights for the dreamlike water scenery stage.

As the rhythm of the music changes, the fountains transform into gentle waves, swaying with graceful postures; at times, they resemble soaring dragons, rushing into the sky with great momentum. The uniquely designed circular fountain creates a 180-degree "giant water curtain" over the Huangpu River, resembling blooming flowers and playful dragons in the water, showcasing a magical spectacle. The full-frame laser system projects brilliant colors and images onto the fountains and water curtain, creating a dazzling array that is mesmerizing. According to the concert's chief director, the concert will revolve around the opening and encore segments, song design, star interactions, and stage shapes, with a completely new arrangement of laser fountains, water curtains, and flames.

The working principle of swimming pool water treatment equipment involves several key processes to ensure the water remains clean and safe for users. 1. **Filtration**: Water from the pool is drawn into the filtration system, where it passes through filters that remove debris, dirt, and other particles. This can include sand filters, cartridge filters, or diatomaceous earth filters. 2. **Disinfection**: After filtration, the water is treated with disinfectants, such as chlorine or bromine, to kill bacteria, viruses, and other harmful microorganisms. Some systems may also use UV light or ozone for disinfection. 3. **pH Balance**: The pH level of the water is monitored and adjusted to maintain a safe and comfortable swimming environment. Proper pH levels help ensure the effectiveness of disinfectants and prevent skin and eye irritation. 4. **Circulation**: The treated water is then circulated back into the pool, ensuring that all areas of the pool receive clean water. This circulation process is essential for maintaining water quality. 5. **Chemical Monitoring**: Regular testing of water chemistry is performed to ensure that the levels of chlorine, pH, alkalinity, and other chemicals are within safe ranges. Automated systems may be used for continuous monitoring and adjustment. Overall, the combination of filtration, disinfection, pH balancing, and circulation works together to keep swimming pool water clean, clear, and safe for swimmers.

The swimming pool water treatment system follows the principle of dynamic balance, achieving thorough purification of the water quality during the circulation process. After the swimming pool water is collected through the overflow channel, it gathers in the balance tank, where it enters the circulation water pipeline along with supplementary water. Driven by the circulation pump, the water flows through a hair collector that filters out hair and larger particles of debris. It then enters the automatic coagulant dosing system; this system uses a precision metering pump to accurately add a coagulant aluminum sulfate solution (10% Al2(SO4)3) in proportion to the circulation water pipeline, causing the colloidal substances in the circulating water to coagulate into larger flocculent particles, which then enter the quartz sand.

Beijing's True Water Project ensures water quality.

Beijing's True Water Project ensures water quality.

"Among nearly 10,000 water stations in Beijing, almost half are unregulated." To rectify the bottled water market in Beijing, yesterday, under the guidance of the Beijing Municipal Government's Social Work Office and the Beijing Municipal Committee's Social Work Committee, the Beijing Bottled Drinking Water Sales Industry Association (hereinafter referred to as the "Association") launched the "True Water Project" in collaboration with Nestlé and six other bottled water companies, as well as Jiao Bi Electric Vehicle Co., Ltd., to ensure that citizens have access to safe bottled water.

The health supervision department requires that swimming pools must disclose water quality.

The health supervision department requires that swimming pools must disclose water quality.

According to a relevant person in charge of the health supervision department, the most concerning issue with swimming pools in summer is water quality. Many swimming pools often fail to change the pool water in a timely manner. On the other hand, due to the high number of swimmers in summer, the chemicals evaporate quickly, and many pools do not monitor this in time, leading to delays in adding chemicals, which cannot ensure the health of the citizens.

Analysis of the Current Development Status of Ozone Treatment Technology for Swimming Pool Water

Analysis of the Current Development Status of Ozone Treatment Technology for Swimming Pool Water

This article analyzes the current development status of ozone treatment technology for swimming pool water. In terms of water treatment, some foreign ozone technology products aimed at households mainly focus on improving water quality, while the various uses of ozonated water have not been emphasized as products, and they have not yet entered the domestic market, presenting a great opportunity for the development of the domestic ozone technology industry. Foreign ozone products strictly control the emission of ozone indoors, using ozone decomposition devices to eliminate excess residual ozone. Additionally, the lack of supporting products for ozone generators is also one of the gaps.
