Sažetak
The main objective of this research was to evaluate the dissolved oxygen delivery capabilities of a new aeration technology, SDOX (Supersaturated dissolved oxygen) compared to a conventional aeration system (bubble diffusers). A laboratory scale of the SDOX unit and the bubble diffuser system were investigated for supplying dissolved oxygen in sludge at different MLSS (Mixed liquor suspended solids) concentrations ranging from 4 to 40 g/L with different ranges of flow rates from 500 to 4, 000 L/hr. The sludge used for this experiment was in endogenous respiration. Increase in MLSS concentration had a negative impact on oxygen transfer process, which is explained with the aid of KLa values. Variations of particle size distribution of the sludge exposed to the SDOX were observed. In addition, values of OUR (Oxygen uptake rate) of the sludge exposed to the SDOX system was measured and compared to the OUR for the same condition of sludge not exposed to the SDOX system.
