This paper presents the results of tests performed on an installation with an aerated microelectrolytic bed (MEL-bed) and sludge sedimentation. The systems were designed in two versions, differing in the aeration method, i.e., a mechanically aerated coagulator (MAC) and an automatically aerated coagulator (AAC). The experiment demonstrated a high (approx. 84%) efficiency of phosphorus removal from a model solution for both versions. The corroding bed was the source of iron in the solution. In the initial phase aeration method affected the phosphorus removal rate, flocculation and sedimentation processes. Physical and chemical changes in the MEL-bed packing were observed.

W pracy zaprezentowano wyniki testów urządzenia z napowietrzanym złożem mikroelektrolitycznym (MEL-bed) i sedymentacją osadu. Urządzenie zaprojektowano w dwóch wersjach, różniących się sposobem napowietrzania. tj.: mechanical aerated coagulator (MAC) oraz automatically aerated coagulator (AAC). Eksperyment wykazał wysoką ok. 84% skuteczność usuwania fosforu z roztworu modelowego dla obydwu wersji. Korodujące złoże było źródłem żelaza w roztworze. Sposób napowietrzania miał wpływ na szybkość usuwania fosforu w początkowej fazie trwającej do 1 h oraz na procesy flokulacji i sedymentacji. Zaobserwowano zmiany fizyczne i chemiczne wypełnienia złoża MEL-bed.
