In the chlorine gas generation system of swimming pools, the core value of titanium anodes lies in their unparalleled electrolytic efficiency and stability. Data shows that electrolytic cells using high-quality coated titanium anodes can achieve a current efficiency of over 85%, which means that for every 1 kilowatt-hour of electricity consumed, more than 450 grams of effective chlorine can be produced, far exceeding the efficiency of about 60% of traditional graphite anodes. This efficient conversion directly reduces electricity costs by 30% to 40%. For a medium-sized commercial swimming pool, the annual electricity budget can be saved by tens of thousands of yuan. The precise manufacturing process of titanium anodes ensures a highly uniform surface catalytic activity, with the standard deviation of the current density distribution being less than 5%. This guarantees that the residual chlorine concentration in the entire swimming pool water remains stable within the ideal range of 0.3 to 0.5 ppm, with minimal fluctuations.
From the perspectives of operating costs and maintenance frequency, the long-term economic benefits of titanium anodes are more prominent. Its design life usually reaches 3 to 5 years, which is more than twice that of ordinary anodes. This reduces the replacement frequency from once a year to once every 3 to 5 years, directly cutting maintenance costs by over 50%. For instance, a certain chain fitness center upgraded its 500 swimming pool systems across the country in 2022. After fully adopting titanium anodes, its annual maintenance budget dropped by 40% and the payback period was shortened to 18 months. This benefit stems from the outstanding corrosion resistance of titanium anodes. Even under working conditions where the pH value fluctuates between 6.5 and 8.5 and the water temperature is maintained at 28 to 30 degrees Celsius throughout the year, the corrosion rate is less than 0.003 millimeters per year, ensuring the long-term continuous operation of the system.
In terms of safety and compliance, titanium anodes offer a crucial guarantee. Compared with directly adding chlorine gas or chlorine tablets, the on-site electrolytic solution of generating chlorine gas from brine completely eliminates the safety risks brought by the storage and transportation of high-concentration chlorine gas, reducing the accident probability by more than 90%. The purity of chlorine gas produced by titanium anodes during operation exceeds 99.8%, and the concentration of by-products is extremely low. This strictly complies with the requirements of public health regulations for swimming pool water quality in various countries, such as China’s “Public Place Hygiene Standards”. A survey report on 1,000 public swimming pools shows that the water quality failure rate of pools using titanium anode systems has significantly decreased from 15% in traditional methods to below 3%, greatly enhancing the health and safety guarantee for swimmers.
Practical application cases have fully demonstrated its reliability. Titanium anode technology has been designated as a core standard configuration in the water treatment system of the swimming venues at the 2023 Asian Games. This system needs to handle a huge water flow of over 1,000 cubic meters per hour and ensure that the error accuracy of the chlorine concentration is within ± 0.05 ppm. Throughout the entire event, the system achieved 100% availability, with a stable chlorine gas generation rate, perfectly supporting the high-intensity usage requirements. This successful experience is driving technological iteration in the global swimming pool industry. Market analysis predicts that within the next five years, the penetration rate of Titanium anodes in swimming pools newly built commercial will increase from the current 35% to over 60%. Therefore, applying titanium anodes to the chlorination system of swimming pools is not only a technical optimization but also a strategic investment concerning efficiency, cost and safety.
