Surface of activated carbon

After Fenton oxidation treatment, wastewater and activated carbon adsorption, this topic activated carbon adsorption experiments using single factor method, examines different PH, activated carbon adsorption dosing quantity and the influence of adsorption time of wastewater COD removal rate, the results show that after Fenton oxidation treatment without having to adjust PH value, according to the 20 g/L after adding the activated carbon reaction 3 h at room temperature, COD removal rate was 47.3%,, BOD/COD value of 0.438 to 0.625.
The research in this paper has laid a theoretical foundation and provided an experimental basis for the practical application of Fenton oxidation and activated carbon adsorption in the pretreatment of natural gas purification maintenance wastewater in UASB reactor.www.activated-carbon-pellets.com

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 range, the relationship between pressure drop and gas velocity basically conforms to Ergun equation.
