【 摘 要 】

The main purpose of the authors is to develop an improved aeration system to be used in wastewater treatment that will reduce the energy consumption by 20% for conventional activated sludge wastewater treatment plants (WWTPs) and by 40% for Moving Bed Biofilm Reactor (MBBR) WWTPs. A new type of aeration system based on fine-bubble diffusers with high endurance and reliability made from corrosion resistant metals is developed. The paper presents the innovative aeration systems with holes smaller than ∅ 1 mm. An ultrasound system is used to clean the diffusers for clogging prevention. Ultrasound systems are used in WWTPs, but in the treatment process and not as an additional solution for anticlogging.
