  1. 1. Are organohalogen compounds in backwash water from swimming pool facilities treatable? : An experimental investigation of removal capacities by different filter materials

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Emma-Helena Ericsson; [2020]
    Nyckelord :AOX; EOX; wastewater treatment plant; column test; granular activated carbon; natural zeolites; Polonite r ; Zugol;

    Sammanfattning : Organohalogen compounds are formed in swimming pool waters when natural organic matter, such as hair, urine or sweat etc., react with the used disinfectant (usually chlorine). Many of the organohalogen compounds are persistent and hazardous for human health and aquatic ecosystems. LÄS MER

  3. 2. Evaluation of sorption behavior of two reactive filter materials using dual column laboratory investigation.
