  • Method and apparatus for continuously controlling denitrification in variable nitrogen loads in wastewater
    Patent number: 7476319
    Abstract: The invention is a method and an apparatus for continuously controlling denitrification in wastewater purification in a sewage treatment plant having at least one denitrification stage under varying nitrogen loads comprising the steps a) provision of excess sludge, b) treatment of the excess sludge according to running parameters determined in advance, c) separation of the treated excess sludge into an organic fraction and an inorganic fraction, d) measurement of actual values for dissolved organic carbon (DOC) in the organic fraction, e) recirculation of the organic fraction to one of the denitrification stages, f) comparison of actual values with predetermined setpoint values for DOC fractions and, in the event of difference between actual values and setpoint values, determination of altered running parameters for treatment of the excess sludge in step b), g) repetition of steps a), to f).
    Type: Grant
