Exploration and practice of powder activated carbon combined with ultrafiltration technology for removing 2-MIB
In response to the odor problem caused by 2-Methylisocamphene(2-MIB)in the source water,a study was conducted on the combined removal of 2-MIB from the source water by Powdered Activated Carbon(PAC)adsorption,coagulation precipitation,ultrafiltration,and sand filtration at a water supply plant in Guangming District,Shenzhen.The results indicate that the PAC adsorption process can effectively remove 2-MIB,but it will cause an increase in the treatment load of the siphon filter,leading to the penetration of algae in the filter and causing a backflow of 2-MIB in the filtered water and effluent.The integrated device of pressure tank ultrafiltration system takes up a small area and does not require water shutdown for renovation.It can overcome the problems of difficult land use in old water plants.By combining with PAC adsorption process,the insufficient efficiency of old water plant filters can be solved.The combined process can leverage the advantages of a single technology to address the 2-MIB water quality problem and improve the overall effluent quality of the water plant.
