Swimming pool water purification process: the scientific configuration and technical escort of professional water treatment system

Scientific Configuration of Pool Water Treatment Systems: Professional Design Enables Healthy Water Quality‌

       Swimming pool is an important place for leisure and fitness in modern life, but the cleanliness and safety of its water quality directly affects user experience and health. A set of scientifically configured swimming pool water treatment system can not only efficiently remove water impurities, kill microorganisms, but also maintain water clarity and transparency, acid-base balance, providing users with a durable and comfortable sports environment. However, swimming pool water treatment is not a simple stack of equipment, but needs to be combined with engineering, water chemistry, microbiology and other multidisciplinary knowledge, through the systematic design of the professional team, in order to achieve the unity of efficiency and economy.

‌Optimizing water flow dynamics with a circulatory system at its core‌

        The core of the swimming pool water treatment system lies in the cycle purification design. The professional team will accurately calculate the circulation cycle and flow rate based on parameters such as pool volume, frequency of use and user carrying capacity. The International Swimming Federation (FINA) suggests that competition swimming pools should have no less than 4 cycles per day, while ordinary leisure swimming pools are usually set to have 2-3 cycles. The circulation cycle determined through the calculation not only meets the timeliness of water renewal, but also avoids the energy waste caused by excessive circulation.

        The selection of circulating water pump requires comprehensive consideration of three elements: head, flow and power. Technicians will be through the pipeline resistance calculation software, simulation of different pipe diameters, the number of elbows, filtration equipment resistance under the hydraulic conditions, and ultimately selected frequency conversion energy-saving pumps. For example, the 50-meter standard swimming pool mostly adopts the parallel design of double pumps, which can not only meet the demand of high-load operation, but also can intelligently reduce the frequency during the low peak hours, saving energy of more than 30% compared with the traditional fixed-frequency pumps. The layout of the water pipeline follows the principle of "short distance and few bends", which reduces the resistance loss along the way under the premise of ensuring uniform distribution of water flow. The water return port adopts the combination design of bottom equalizer and overflow tank to ensure the synchronous collection of floating matters on the surface of the pool water and sediments on the bottom, avoiding the "stagnant water area" caused by the traditional single-point water return.

‌Filtering system hierarchical processing for accurate interception‌

       The filtration unit is the first line of defense in water purification. In professional design, the selection of quartz sand filtration and diatomaceous earth filtration needs to be combined with operating costs and water quality requirements. Quartz sand filter with 0.45mm filtration precision and backwashing convenience, become the first choice of most swimming pools; and more demanding competition swimming pools will use diatomaceous earth filtration precision of 2μm system, its ability to retain microorganisms to enhance the 80%. Multi-media filters through the anthracite, activated carbon, garnet layers of combinations, can synchronize the removal of suspended particles, organic pigmentation and odor substances. .

      For seasonal water quality fluctuation, the professional team will set up a pre-filter. The automatic hair collector adopts double-layer stainless steel filter mesh, which can effectively intercept hair fibers and other large particles of impurities to avoid clogging the main filter. In the rainy season or high load use time, polymer flocculant can be temporarily injected to make tiny colloidal particles aggregated and sunk through the charge neutralization effect to enhance the filtration efficiency. These details not only extend the service life of the core equipment, but also reduce the intensity of routine maintenance.

‌Intelligent control of sterilization system, balancing safety and comfort‌

       Disinfection is directly related to the safety of water quality. Traditional chlorine disinfection is evolving into a compound disinfection system, and the professional team will match the best solution according to the type of pool: indoor pools are more suitable for ozone + chlorine disinfection, using the strong oxidizing properties of ozone to reduce the amount of chlorine dosage, to avoid the accumulation of volatile disinfection by-products (DBPs) in the enclosed space; open-air pools are mostly used in salt-electrolytic chlorine generators, generating sodium hypochlorite through the electrolysis of brine, which not only ensure the continuous disinfection effect, but also alleviate the odor of chlorine irritation. The salt electrolysis chlorine generator is used in open-air pools to generate sodium hypochlorite through electrolysis of salt water, which not only ensures the continuous disinfection effect, but also alleviates the chlorine irritating odor.

       Intelligent control system is the standard for modern swimming pools. The professional ORP (Oxidation Reduction Potential) monitor provides real-time feedback on the disinfection capacity of the water body, and the linkage metering pump automatically adjusts the amount of disinfectant dosage to accurately control the residual chlorine concentration in the healthy range of 0.3-1.0 ppm. pH sensors, together with the automatic sodium bicarbonate dosage device, can maintain the pH value of the water body in the optimal range of 7.2-7.6, which not only ensures the disinfection efficiency but also avoids the irritation to the skin and mucous membranes. For children's pools or spa pools, a UV disinfection module is also added to instantly inactivate pathogenic microorganisms through UV radiation at 253.7nm, building a multi-protection barrier.

‌Water Balancing Systems: Invisible Precision Engineering‌

         The professional design not only focuses on pollutant removal, but also on the chemical balance of the water body. The total alkalinity regulator automatically monitors carbonate hardness to prevent drastic fluctuations in pH; the calcium hardness controller avoids concrete erosion caused by overly soft water or scale produced by overly hard water; and the total dissolved solids (TDS) monitor provides timely warnings of salt accumulation and guides scientific water changes. These sophisticated controls ensure that the water body both complies with the Swimming Pool Water Quality Standards (CJ/T244-2016) and maintains its friendliness to building materials and the human body.

         The professional team will also establish a mathematical model of water quality, taking into account the ambient temperature, sunlight intensity, pedestrian load and other variables, and preset a variety of operating modes. For example, the frequency of circulation and disinfectant dosage is automatically increased during the high temperature period in summer, and switched to the energy-saving mode in winter; the state of the equipment is remotely monitored through the Internet of Things platform to realize the early warning of failures and maintenance reminders. This dynamic management system saves 15% of water and 20% of electricity compared with the traditional fixed-parameter mode, and at the same time improves the water quality compliance rate to more than 99.8%.

‌Full-cycle service from drawing to operation and maintenance‌

       An excellent water treatment system requires professional services throughout the whole process of design, construction, commissioning, operation and maintenance. Senior engineers will test the mineral content of the water source, analyze the pollen characteristics of the surrounding vegetation, and even consider the impact of building ventilation on chlorine volatilization during on-site mapping. The construction phase strictly follows the principles of fluid dynamics to avoid the loss of circulation efficiency caused by air collection in the pipeline. A 72-hour continuous water quality test is carried out during the commissioning period to establish a personalized parameter database. After delivery, quarterly system check-ups are provided to regularly replace filter media, calibrate sensors, and optimize control procedures to ensure continued efficient operation of the system.

       Scientific and reasonable swimming pool water treatment system is the crystallization of professional wisdom and engineering experience. Choose a team with fluid simulation and analysis capabilities, mastery of cutting-edge water treatment technology, and rich project experience, in order to create a water treatment system that integrates high efficiency purification, intelligent control, energy saving and environmental protection, so that every pool of blue water becomes a reliable guarantee of a healthy life.
