This paper assesses the state of theoretical and experimental modeling of air-lift technology. A calculation of the energy contribution of atmospheric pressure during air injection is presented. Energy accumulation, predominantly in the form of compressed gas heat, is established. The most efficient energy modes for using air-lift technology are identified. A direction for modernizing gas-air mixture circulation designs to achieve additional energy parameters is identified. A design with vertical water circulation is proposed. A model for the circulation of a water-air mixture in a vertical plane is proposed. The explicit use of a pipe with a downward water flow in the air-lift technique is justified. A pressure imbalance in the ascending and descending fluid flows is established. Compressor energy consumption is substantiated as being an order of magnitude lower than the power of the circulating movement of the water-air mixture. Directions for increasing the energy performance and power of the air-lift technique with increasing structural dimensions are identified by reducing losses and increasing the operating time of each portion of air during the lift.
