“…Furthermore, pore geometry has an influence on DWP with round pores being rigid and acting as a control opening that can withstand high pressure, whereas membrane pores/slits can expand when the pressure increases. However, a low DWP does not guarantee the best performance as there is a minimum pressure required for the proper distribution of the air (Rosso et al 2012). Such analysis is scantly reported and there is minimal guidelines or information available for the design of diffusers in published literature.…”

Air diffusers or spargers have since been used in separation processes that include conventional wastewater treatment. Over the years, there has been advancements in diffuser design in terms of shape, pore size, orientation and materials of construction as a way of mitigating challenges such as fouling, clogging, energy consumption and poor system efficiency. Some of the available air diffusers are inadequate to solve most of these challenges due to reduced quality and increased quantity of wastewater being treated. Additionally, there is a paucity of information regarding air diffuser design and their effect on operational parameters in wastewater treatment. This review seeks to address the advancement in diffuser design and also the effects of design factors including parameters of air diffusers with a focus of their use in a column flotation system for wastewater treatment.
