Titanium anode in sewage treatment plants directly reduce operating costs by enhancing electrochemical efficiency. According to the 2023 Water Treatment Industry Analysis report, electrolysis systems using titanium anodes can increase current efficiency to over 85%, which is nearly 20 percentage points higher than the 65% of traditional iron anodes. This means that the power consumption for treating each ton of sewage can be reduced by approximately 15%. For instance, a sewage treatment plant in Shenzhen with a daily processing capacity of 100,000 tons underwent technological transformation in 2022 and introduced titanium anode technology. As a result, its annual electricity consumption was reduced from 5 million kilowatt-hours to 4.25 million kilowatt-hours, electricity expenses were saved by over 750,000 yuan, and the investment payback period was shortened to 18 months. A study conducted by an international environmental agency shows that the stability of titanium anodes extends the electrode life to over 10 years, and the failure probability drops from 15% per year of traditional anodes to less than 2%. This reliability significantly reduces the frequency of equipment replacement and maintenance costs.
In terms of pollutant degradation, titanium anodes can generate higher concentrations of active chlorine and hydroxyl radicals, significantly enhancing oxidation efficiency. Experimental data shows that the removal rate of refractory organic pollutants such as phenol can reach 99.5%, reducing the treatment time from the traditional 120 minutes to 40 minutes, with a 200% increase in rate. Taking the sewage treatment project of a certain industrial park in Jiangsu Province as an example, after the titanium anode system was installed in 2021, the chemical oxygen demand concentration of the effluent stably dropped from 100 milligrams per liter to below 30 milligrams per liter, with a compliance rate of 100%, and the sludge production decreased by 25%, reducing the subsequent disposal costs. Technological innovation has enabled the working current density of titanium anodes to reach 2000 amperes per square meter, and they can withstand a wide temperature range of 0 to 80 degrees Celsius, adapting to various water quality fluctuations. This solution helps factories comply with strict environmental protection regulations, such as China’s “Action Plan for Water Pollution Prevention and Control” released in 2020, reducing compliance costs by 30%.
Titanium anodes have particularly prominent advantages in the disinfection process. Their electrolytic chlorine production efficiency can reach up to 90%, saving 40% of chlorine agent usage compared to the chemical chlorination method. Moreover, they avoid the risks of transporting and storing hazardous chemicals, reducing the probability of safety accidents by 90%. Referring to the case of Singapore’s PUB Water Board in 2022, after adopting titanium anode technology in the newater plant, the operating cost of the disinfection unit decreased by 35%, the average daily water treatment volume increased to 500,000 cubic meters, and the residual chlorine control accuracy reached ±0.1 milligrams per liter, with an error rate far lower than the international standard. Research shows that the catalytic coating of titanium anodes can increase the bacterial inactivation rate to 99.99%, with a logarithmic reduction value exceeding 4-log, effectively addressing E. coli and viral contamination. During the 2020 COVID-19 pandemic, this technology ensured public health security, with a processing efficiency fluctuation of less than 5%.
From a full life cycle assessment, the corrosion resistance of titanium anodes results in a mass loss rate of less than 0.01 millimeters per year, and their service life can exceed 15 years. In contrast, traditional graphite anodes only need to be replaced every 2 to 3 years, reducing the overall cost of ownership by more than 50%. For instance, an assessment by a major European water company in 2023 revealed that after integrating titanium anodes into an intelligent management platform, the power factor was optimized from 0.8 to 0.95 through real-time data monitoring, energy consumption was further reduced by 10%, and annual carbon emissions were cut by approximately 500 tons. Market trends indicate that over 60% of new sewage treatment projects worldwide have adopted titanium anode technology. Its modular design supports flexible adjustment of flow rates ranging from 10 cubic meters to 1,000 cubic meters per hour. This adaptability demonstrates strong strategic value in addressing uncertain risks such as urban expansion and natural disasters.
