Evaluation of an energy-saving aerator applied in wastewater treatment

Project Details


The carbon reduction efficiency of this development project is expected to be as follows:1. The pressure loss can be below 30 mm Aq. The smaller the pressure loss, the less energy is wasted by the front-end equipment (blower).2. The agitation range is large, and a single product can be manufactured with a surface spread of more than 2 square meters.3. Since the dissolved oxygen transfer effect is better than the traditional aeration pan, the MLSS concentration can be greatly increased to about 8,000 mg/L.4. Due to the substantial improvement of MLSS, the COD removal rate can be increased by about 10%, and the highest target is expected to reach a removal rate of 95%.5. The residence time is shortened by 10%, or the treated water volume is increased by 15%.6. The blower can be derated by 25% or down to 55 Hz.
