How to choose an ozone catalyst

Ozone catalyst technology serves the advanced ozone oxidation process, which combines the strong oxidation of ozone with the adsorption and catalytic characteristics of the catalyst to more effectively solve various problems in the process of ozone treatment of industrial wastewater, improve the ozone utilization rate, improve the efficiency of ozone treatment, reduce the overall operating costs, and improve the biodegradability of wastewater. So how to choose an ozone catalyst?

1. High specific surface area

When the wastewater is in contact with the ozone catalyst, the organic matter in the water will be first enriched on the surface of the catalyst. After the ozone is injected into the system, the ozone will achieve efficient mass transfer and oxidation reaction on the surface of the ozone catalyst. As the concentration of organic matter enriched on the surface of the ozone catalyst is high, the probability of participating in the reaction will be higher. The degradation is faster and more thorough, and the COD removal rate will be greatly improved.

2, the effective active ingredients evenly distributed

There are many kinds of ozone catalysts on the market, some only have active materials on the surface, and we should choose ozone catalysts with uniform distribution of efficient catalytic active materials inside and outside. Efficient catalysis of active ingredients can reduce the activation energy of oxidative decomposition of organic compounds, and ozone molecules are easy to decompose under the action of active catalysts to produce strong oxidizing free radicals such as hydroxyl radicals, thereby improving the oxidation capacity and reaction rate of ozone, increasing the conversion rate of O3, and reducing the residual ozone in the tail gas.

3. Service life

In addition to activity and selectivity, the stability (or service life) of the catalyst is also a factor that cannot be ignored. Long-life catalysts can not only reduce the frequency of replacement, but also reduce the cost of related replacement and treatment. Therefore, when selecting ozone catalysts, priority should be given to those products that have been proven to have a long service life.

       4, the most important thing is to choose different specifications of ozone catalyst according to the application scenario is the key, Hunan Minstrontionzhuang is a professional production of ozone catalyst company, we have from Nanjing University, Southeast University, the Chinese Academy of Sciences Shanghai Institute for Advanced Study of technical experts, and established a professional laboratory.
