The composition of wastewater from dairy processing plants makes it highly suitable for biological wastewater treatment processing. As well anaerobic biological treatment of the wastewater there is also the option of applying anaerobic biological processes. By applying anaerobic technology a large part of the organic load in the wastewater can be removed and converted into energy-rich biogas. In addition, the anaerobic technology can be used in dairies to produce biogas from waste whey. The biogas which is generated can be used to produce electrical and/or thermal energy.
