Hydraulic Characteristics of the Airlift Pump

Abstract: Airlift pumps are the simplest devices used for lifting and transporting of liquid in water and wastewater systems. They constitute the subject of interest in numerous studies, focusing on their two-phase flow. The knowledge of two-phase flow parameters is necessary for the correct design of an airlift pump. In the available literature on the subject, one will find numerous models describing the two-phase gas-liquid flow. One of the most popular is the Zuber-Findlay model, also called the slip model. The subje… Show more

“…The advantages of MBBR (moving bed biofilm reactor) reactors include high tolerance to water temperature changes and heterogeneity of charges during the treatment process (Andreottola et al, 2000;Ødegaard, 2004;Leiknes and Ødegaard, 2007;McQuarrie and Boltz, 2011). The efficiency of the reactors depends, inter alia, on the types of moving beds (biomass carriers) used (Kujawiak et al, 2017(Kujawiak et al, , 2018(Kujawiak et al, , 2020. New moving bed technologies, e.g.…”

“…Moving beds: one of the most dynamically developing treatment technologies in the last two decades. The working environment for this type of bed is the classic MBBR (moving bed biofilm reactor) reactors and their numerous modifications in hybrid systems (Ødegaard et al, 2004;Kujawiak et al, 2017;Kujawiak et al, 2018;Kujawiak et al, 2020). A significant number of this type of treatment plants based on MBBR technology has been built worldwide.…”
