The flotation wastewater treatment was considered in the paper. The main stages and parameters of flotation process were pointed out. The multistage flotation model considering all main stages of flotation process is presented. However, its main disadvantage is that for the definition of constant characterizing the bubble-particle aggregate formation, the constant value of superficial gas velocity was used, which is incorrect for horizontal flow flotation tank. The modified multistage flotation model with superficial gas velocity as the function of time was proposed. The experiments were carried out on a laboratory setup with a pneumohydraulic system of aeration in order to verify the proposed model. The comparison of experimental and theoretical results proved the importance of superficial gas velocity change consideration.
