Activated carbon filtration is a commonly used technology based on the adsorption of contaminants onto the surface of a filter. This method is effective in removing certain organics (such as unwanted taste and odours, micropollutants), chlorine, fluorine or radon from drinking water or wastewater.
Competitive adsorption of cadmium and phenol on activated carbon produced from municipal sludge M. Al-Malack and M. Daud, JECE, Volume 5, Issue 3, June 2017, Pages 2718-2729 Here, the authors demonstrated that sewage sludge can be a potential precursor to obtain activated carbons, which in turn, are able to uptake phenol and cadmium from
