This article presents different aeration systems for biological wastewater treatment, their classification, also advantages and disadvantages of the most common aeration methods - pneumatic and mechanical are described. Also, proposals to reduce the energy consumption of aeration systems by maintaining the optimal range of dissolved oxygen concentration at different points of the aeration tank, depending on its type, have been prepared.
