  • Method for treating sewage sludge and wastewater treatment plant
    Patent number: 9556049
    Abstract: The invention describes a method for treating sewage sludge through the treatment steps of hydrolyzing (2) the sewage sludge (1) and digesting (11) the hydrolyzed sewage sludge (10), which has undergone hydrolysis (2), for the anaerobic treatment of the sewage sludge (1), and through the step of separating phosphate from the at least partially treated sewage sludge (3). Phosphate is separated after the treatment step of hydrolyzing (2) and before the treatment step of digesting (11) the hydrolyzed sewage sludge (3), wherein the sewage sludge (10), without the phosphate portion separated in the phosphate separation step, is fed to the anaerobic treatment performed through digestion (11).

  • Method for wastewater treatment and wastewater treatment system
    Patent number: 8641902
    Abstract: The invention relates to a method for wastewater treatment utilizing an anaerobic treatment of primary sludge (PS) in a septic tank (5), and a separate treatment of excess sludge (ÜS). The excess sludge (ÜS) is separated from the primary sludge (PS) before the anaerobic treatment, solubilized in a hydrolysis treatment and liquefied, and subjected to a separate anaerobic treatment independently of the primary sludge (PS).

  • METHOD FOR WASTEWATER TREATMENT AND WASTEWATER TREATMENT SYSTEM
    Publication number: 20110014684
    Abstract: The invention relates to a method for wastewater treatment utilizing an anaerobic treatment of primary sludge (PS) in a septic tank (5), and a separate treatment of excess sludge (US). The excess sludge (US) is separated from the primary sludge (PS) before the anaerobic treatment, solubilized in a hydrolysis treatment and liquefied, and subjected to a separate anaerobic treatment independently of the primary sludge (PS).
