  4. 3. Ammonium Feedback Control in Wastewater Treatment Plants

    Författare :Linda Åmand; Bengt Carlsson; Peter Vanrolleghem; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeration control; ammonium feedback control; biological nitrogen removal; full-scale experiments; gain scheduling control; PI control; process control; repetitive control; wastewater treatment; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : The aeration process is often the single largest consumer of electricity in a wastewater treatment plant. Aeration in biological reactors provides microorganisms with oxygen which is required to convert ammonium to nitrate. Ammonium is toxic for aqueous ecosystems and contributes to eutrophication.
