  • SEM micrographs of the austenitic stainless steel corrosion in asphalt fumes

    Dane Badawcze
    open access

    The dataset contains the scanning electron microscopy (SEM) studies of the austenitic stainless steels: AISI 304, AISI 316, AISI 321 and duplex stainless steel AISI 2205. The samples were polished and exposed to the installation carrying asphalt fumes at elevated temperatures (approx. ~210-240 Celsius). The exposition duration was three months. Some...

  • Wyniki sulfammox (SRAO)

    • D. Derwis (Grubba)

    Two granular sequencing batch reactors were operated for 160 days under anammox conditions, comparing the Anammox process and Sulfate Reduction Ammonium Oxidation process. The study aimed to investigate whether increasing the concentration of SO42- could enhance N removal rates under anaerobic conditions, and whether SO42- reduction and anammox processes...

  • Sulfammox process_task 1

    Dane Badawcze
    open access

    Anaerobic ammonia-oxidizing bacteria have a more comprehensive metabolism thanexpected - there may be other electron acceptors that oxidize ammonium nitrogen under anaerobicconditions, in addition to the well-known nitrite nitrogen, one of which is sulfate in the sulfammoxprocess. Sulfate-containing compounds are part of the medium for the anammox process,...
