Product Description

Titanium anode for ammonia nitrogen wastewater treatment

Ammonia nitrogen wastewater mainly comes from chemical fertilizer, coking, petrochemical, pharmaceutical, food, landfill, etc. A large amount of ammonia nitrogen wastewater discharged into water bodies not only causes eutrophication of water bodies, resulting in black and smelly water bodies, increasing the difficulty and cost of water treatment, and even toxic effects on people and organisms.
At present, with the rapid development of chemical fertilizer, petrochemical and other industries, the resulting high nitrogen nitrogen wastewater has become one of the constraints of the development of the industry.Nitrogen and nitrogen are one of the important causes of pollution, especially the pollution caused by high concentration ammonia nitrogen wastewater. Therefore, the economic and effective control of high concentration pollution has become an important topic of the current environmental protection workers, has been highly valued by the industry. 
Titanium is commonly used material for anodes in wastewater treatment applications due to its high resistance to corrosion. In the treatment of ammonia nitrogen wastewater, titanium anodes can be used in a variety of electrochemical processes, including electrocoagulation, electrooxidation, and electrochemical reduction. In electrocoagulation, a direct current is applied to the titanium anode, causing metal ions to dissolve into the wastewater, which then reacts with the pollutants. This reaction causes the pollutants to coagulate and settle, making it easier to remove them from the wastewater. In electrooxidation, the titanium anode is used to generate hydroxyl radicals, which can break down pollutants in the wastewater. This process can be effective for treating a wide range of pollutants, including ammonia nitrogen. In electrochemical reduction, the titanium anode is used to generate hydrogen gas, which can react with pollutants in the wastewater to break them down into harmless substances.

Overall, the use of a titanium anode in the treatment of ammonia nitrogen wastewater can be an effective and efficient method for reducing the concentration of pollutants in the wastewater. However, the specific electrochemical process used will depend on the specific characteristics of the wastewater and the desired treatment outcomes.

Here is an example of a real-world application of titanium anodes for ammonia nitrogen wastewater treatment:

Case Study: Wastewater Treatment Plant in China


A wastewater treatment plant in China was experiencing difficulties in treating ammonia nitrogen in their wastewater effluent. The plant was using traditional biological methods for treatment, but the process was not efficient in removing high levels of ammonia nitrogen.

To address the issue, the plant installed a new electrochemical system using titanium anodes with an IrO2 coating. The system utilized a process called electrooxidation, which applies a voltage to the electrodes to generate active oxidizing agents that react with ammonia nitrogen and other pollutants in the wastewater.

The electrochemical system was designed with multiple titanium anodes in a reactor tank, and the wastewater was continuously circulated through the reactor to ensure effective treatment. The process allowed for complete removal of ammonia nitrogen and other pollutants, and the treated wastewater met the local discharge standards.

The use of titanium anodes with an IrO2 coating proved to be an effective solution for the plant's ammonia nitrogen treatment needs. The electrochemical system was able to achieve high removal rates of ammonia nitrogen, while also being cost-effective and requiring low maintenance.

Overall, this case study highlights the potential benefits of using titanium anodes for ammonia nitrogen wastewater treatment, particularly in situations where traditional treatment methods are not effective.
