Recent advances in wastewater treatment using induced-air-flotation (IAF)

Basic design considerations for both the mechanical and hydraulically actuated IAF concepts, the various factors to consider in applying the IAF machine to a wastewater treatment situation, IAF machine flotation kinetics from the standpoint of ''pilot test scale-up'', and the performance of the IAF machines used in treating oilfield production wastewaters and in removing suspended solids from industrial wastewaters, are discussed.
