How to make better granular activated carbon

The combined process of catalytic oxidation and activated carbon filtration has higher water purification efficiency. When the influent ozone concentration is 0~0.1 mg/L and influent UV254 is 0.020~0.030 L /em, the average removal rate of UV2sa by catalytic and ozone activated carbon is 30% and 21%,activated carbon wholesale   respectively. The removal rate of UV2s4 and DOC by activated carbon filtration is the highest when influent water quality and liquid phase ozone concentration is moderate. The DOC removal rate reached the maximum when the liquid phase ozone relative concentration (O/DOC) was about 0.3. The organic matter content and ozone concentration of activated carbon influent after catalytic oxidation are low, which is beneficial to the adsorption capacity and surface properties of activated carbon. In addition, metal oxides lost by the catalyst can be adsorbed by the activated carbon, which also helps to promote the decomposition of ozone on the surface of the activated carbon. activated carbon for gold recovery
