In wastewater treatment processes, blowers are important equipment in the aeration system, and their power consumption accounts for 50–70% of the total electricity consumption in wastewater treatment plants. In the aeration process for wastewater treatment, air is introduced primarily to serve two purposes: oxygenation – the treatment of wastewater using the activated sludge method is an aerobic biological treatment process. Aerobic microorganisms are needed to absorb organic matter in water, oxidize and break it down into carbon dioxide and water, while simultaneously reproducing and multiplying. During this process, it is necessary to provide sufficient dissolved oxygen to the microorganisms in the activated sludge to meet their needs for growth and metabolic activities. The first function of forced aeration is to deliver oxygen, by transferring the oxygen from the air into the water through air-water contact. Therefore, the calculation of air volume in forced aeration is also determined based on the oxygen demand of microorganisms, taking into account various influencing factors such as environmental conditions, water quality conditions, and aeration efficiency. Secondly, mixing by stirring: During the mixing process, on one hand, it keeps the activated sludge in a suspended state within the aeration tank, allowing it to come into full contact with the wastewater; this improves the mass transfer conditions of pollutants within the water treatment system and enhances the efficiency of treatment. On the other hand, it provides favorable conditions for the diffusion and transfer of oxygen in the liquid phase. In products such as blowers, aeration equipment, and water pumps, choosing efficient and durable equipment can help each wastewater treatment plant save 15–20% in energy consumption. At the same time, as technology continues to mature, the scale of application for air-suspended fans will grow larger and larger; the widespread use of such fans will directly affect the energy savings and economic benefits associated with the wastewater treatment process. https://www.raetts.com https://www.raetts.cn
