Abstract

In recent years the process of sludge disintegration gains growing interest in the scientific community. This is due to the significant advantages of this process, such as: (i) increasing the efficiency of methane fermentation process, (ii) reducing the volume of wasted sludge, (iii) improvement in digested sludge dewatering, and (iv) the intensification of biogenic compounds removal from wastewater (Huan et al., 2009). By using the additional energy, the process of disintegration leads to an increase in the concentration of organic compounds in the sludge liquid (Zubrowska-Sudol & Walczak, 2014). Disintegrated sludge thus becomes a potential substrate for the microorganisms responsible for fermentation or nutrients removal from wastewater. Many authors, analysing the process of organic compounds release, determine COD values of organic compounds with a diameter <0.45 microns, assuming that they represent soluble compounds. In fact, these are not only soluble (<0.1 μm), but also colloidal compounds with a diameter of 0.1-0.45 mm.
