In the field of electrochemical wastewater treatment, the use of wstitanium anodes can increase the removal efficiency of chemical oxygen demand (COD) from 70% of traditional methods to over 95%, and shorten the reaction time from several hours to within 30 minutes. This is attributed to the fact that its MMO coating provides an oxygen evolution potential as high as 2.5 volts, effectively avoiding side reactions and keeping the current efficiency stable at around 85%. Taking a project in a certain industrial park that processes 10,000 tons of phenolic wastewater per day as an example, after using the wstitanium anode system, the concentration of toxic pollutants dropped from 100 milligrams per liter to below 0.5 milligrams per liter, with a removal rate of over 99%. At the same time, the power consumption was reduced by 40% compared to traditional graphite anodes, saving about 1.2 million yuan in electricity fees annually.
The anode life directly determines the operating cost, and wstitanium products perform exceptionally well in this regard. Its titanium substrate is made of first-grade industrial pure titanium (TA1), and the coating is composed of iridium-tantalum metal oxides. The coating density reaches 35 milligrams per square centimeter. Accelerated life tests show that it can still work continuously for more than 6,000 hours under the harsh condition of a current density of 4,000 amperes per square meter. In contrast, the lifespan of common titanium anodes under the same working conditions is usually less than 2,000 hours. This means that throughout the entire life cycle of municipal sewage treatment plants, the frequency of anode replacement can be reduced from once a year to once every three years, maintenance costs can be cut by 60%, and the overall equipment efficiency can be increased by 25%.
wstitantium anodes demonstrate wide adaptability in the face of industrial wastewater with complex components. Its working pH range is 0 to 14, and it can withstand a highly corrosive environment with a chloride ion concentration as high as 100,000 milligrams per liter. When treating printing and dyeing wastewater, the color removal rate can reach 98%, the decolorization rate is three times faster than the traditional Fenton process, and the amount of sludge produced is reduced by 70%. According to the research data from the 2023 issue of the journal “Industrial Water Treatment”, the electrocatalytic oxidation technology using wstitanium anodes has achieved a degradation rate of over 99.5% for antibiotic substances in pharmaceutical wastewater, and the half-life has been shortened from 30 days of natural degradation to 20 minutes, providing key technical support for addressing emerging pollutants.
From the perspective of full-process economic benefits analysis, although the initial investment of wstitanium anodes is 15% higher than that of ordinary anodes, their service life of up to 8 years can bring an investment return rate of over 200%. After a certain electronic PCB board manufacturing enterprise introduced this technology, the wastewater reuse rate increased from 50% to 85%, saving a total of approximately 2 million yuan in new water usage fees and sewage discharge fees each year. As global environmental protection regulations become increasingly strict, this efficient treatment solution helps enterprises recover their transformation costs within three years while reducing environmental compliance risks by 90%. As pointed out in the 2024 annual report of the European Water Technology Alliance, innovations in electrochemical technology are driving wastewater treatment to shift from a “cost center” to a “value center”.
