Abstract EN
The feasibility of ozonation process for 2-mercaptobenzothiazole (2-MBT) removal follows from results of ozonation of the model wastewater.
Total removal of 2-MBT was observed after 20 minutes of ozonation.
Very good reproducibility of repeated ozonation trials including sampling and analysis was observed.
However, the majority of dissolved organic carbon (DOC) and chemical oxygen demand (COD) remained in the reaction mixture.
Benzothiazole (BT) and 2-hydroxybenzothiazole (OBT) intermediates were identified during degradation of 2-MBT with ozone.
In addition to the above benzothiazole derivatives, the creation of some other organic compounds follows from results of mass balance.
The best fits of experimental data were obtained using the first kinetic model for 2-MBT and zero-order kinetic model for COD and DOC.
The reaction time of 60 minutes can be considered as effective with regard to controlled oxidation in order to increase a portion of partially oxidized substances.
Higher biodegradability and lower toxicity of ozonation products on respiration activity of activated sludge microorganisms was observed at higher ozonation time.
