Effect of dissolved organic matter (DOM) and biofilm on the adsorption capacity of powdered activated carbon in activated sludge
... caused by the adsorption of the metabolites of microorganisms, other dissolved organic matters (DOM) and biofilm attached onto PAC. However, it is not clear that the effect of DOM and biofilm ... adsorption of glucose and/ or DOM on PAC would be neglected and most of organic carbon on PAC would be originated from biofilm. Therefore, it is concluded that the developmen...
