At present, the organic pollution of drinking water source is relatively serious. The organic pollutants themselves are not only highly toxic, but also may generate halogenated disinfection by-products (DBPs) after chlorination disinfection. Meanwhile, the existence of organic compounds will reduce the biological stability of drinking water and lead to the secondary reproduction of microorganisms in the pipe network. Therefore, it is important to reduce the content of organic pollutants in drinking water. Conventional water treatment process has low removal efficiency for organic pollutants, so it is imperative to seek economic and efficient treatment technology. On the basis of giving full play to the advantages of ozone oxidation to remove organic matter, ozone catalytic oxidation technology can induce the formation of highly oxidizing hydroxyl radical (-Oh), which can effectively remove trace organic pollutants that are difficult to degrade in water and reduce the content of ozone oxidation by-products. It is a kind of water treatment method with great prospect.activated carbon for gold recovery  Laboratory studies have shown that ceramic honeycomb activated carbon catalytic ozone oxidation technology and removal of trace organic matter in water has more obvious advantages, but the catalytic oxidation and active carbon process characteristics to be in-depth study, therefore the pilot was investigated through honeycomb ceramic catalytic ozonation and activated carbon catalytic ozonation and activated carbon filter combination process operation characteristics. activated carbon wholesale

Activated carbon adsorption, is the use of activated carbon on the solid surface of the water adsorption or a variety of substances, in order to achieve the role of water purification. The adsorption of activated carbon is produced in two aspects.One is that the molecules inside the activated carbon are subjected to equal forces in all directions while the molecules on the surface are subjected to uneven forces.This makes other points adsorbed on its surface, which is physical adsorption;The other is due to the chemical action between activated carbon and adsorbed substances, which is chemical adsorption.The adsorption of activated carbon is the result of the comprehensive action of the above two kinds of adsorption.https://www.granular-activated-carbon.com  When the adsorption speed and desorption speed of activated carbon in the solution is equal, that is, the number of activated carbon adsorption is equal to the number of desorption, the concentration of the adsorbed material in the solution and the concentration on the surface of activated carbon are no longer intermingled, that is, to achieve the balance, the dynamic balance at this time is called activated carbon adsorption balance. coal based granular activated carbon  Adsorption capacity refers to the amount of adsorbents adsorbed on the adsorbent per unit mass under certain conditions. It is usually expressed in terms of K adsorbents /kg of adsorbent or mass percentage, which is a sign of the adsorption capacity of the adsorbent. In industry, the amount of adsorption is called the activity of the adsorbent. The activity of the adsorbent can be expressed in two ways :(1) the static activity of the adsorbentUnder certain conditions, the equilibrium adsorption capacity of the adsorbent is its static activity.For a certain adsorption system, the static activity depends only on the adsorption temperature and the concentration or partial pressure of the adsorbed substance. Dynamic activity of adsorbents

The experimental results show that the adsorption equilibrium of pure components is in good agreement with the Langmuir equation. In the case of multi-component adsorption, due to the competition and interference between each component, the component with strong adsorption ability can replace the other component that has been absorbed, so that the penetration curve of each component has obvious changes. activated carbon for gold recovery  The penetration point of the components with relatively weak adsorption capacity was significantly advanced, while the penetration time of the components with strong adsorption capacity was delayed. In this paper, E-L equation and IAST theory are used for theoretical prediction and analysis of multi-component adsorption equilibrium, and compared with experimental results.activated carbon wholesale   The results show that although the prediction of total adsorption amount by E-L equation is in good agreement with the experimental results, the prediction of each component adsorption amount by E-L equation often produces positive and negative deviation, and the average error is usually more than 20%. However, IAST can eliminate the positive and negative deviation well, and the average error is less than 10%, which is more consistent with the experimental results. The operating parameters showed that the adsorption capacity of activated carbon would decrease with the increase of temperature, gas velocity or humidity. The appropriate operating range is: temperature within 40℃, gas speed between 0.1~0.5 m/s, humidity is best not more than 40%. In this rang
