Using measurements of the sludge level and the dried solid content, the removal of primary sludge from the primary settlement tanks can be optimised to suit the hydraulic and weather-related conditions. Load-related removal facilitates more balanced charging of the digester and a more constant rate of gas production for downstream block-type thermal power stations (BTPS). If neither pre-thickeners nor mechanical pre-thickening are used, the volume of sludge can be significantly reduced. This is highly beneficial in terms of the savings in pump energy and in heat energy for the digestion process.
