Performance and design characteristics of airlift pumps
Airlift pumps can be used in cages, floating raceways, closed or recirculating systems, pond de-stratification or aeration, return An airlift pump is a pump that has low suction and moderate discharge of liquid and entrained solids. The pump injects compressed air at the bottom of the discharge pipe which is immersed in the liquid. The compressed air mixes with the liquid causing the air-water mixture to be less dense than the rest of the liquid around it and therefore is displaced upwards through the discharge pipAirlift pump

Air-Lift Water Pumps Sustainable Engineering for
An air-lift pump is a device which is used to lift water from a well or a sump with the use of compressed air. The compressed air is made to mix with the water. It is well known that the density of water is more than the density The operating principle of an airlift pump involves utilizing buoyancy force to propel a two-or three-phase fluid through a vertical pipe that is partially submerged in the fluid, with openings at(PDF) Review study on airlift pumping systems

Experimental Evaluation of Airlift Performance for Vertical
An airlift pump is a device for transporting slurries and liquids using compressed gas injection. More than a two hundred years ago, Carl Luster introduced the concept of the first airlift pump in Germany (Ahmed et al. 2016).The pump consists of a vertical riser pipe and an air injector; the injector is often installed at or near the bottom of airlift pumps used to lift water vertically. Spotte (1970) presented data on the vertical lift capacity of airlift "pumps 2.5-15 cm in diameter and 40-70% submerged. Castro et al. (1975) reported on the pumping rate of airlift pumps 1.27-7.62 cm in diameter, 0.3 to 3.7 m long, and 40-70% submerged.Airlift Pump Final

Transport and Pumping of Sewage Sludge and Biosolids
Biosolids pumps have many uses in a municipal wastewater treatment plant. Settled primary sludge must be moved regularly; activated sludge must be returned continuously to aeration tanks, with the extra biosolids wasted; scum must be pumped to digestion tanks; and biosolids must be recirculated and transferred within the plant in processes such as Airlift pumps are available in a range of sizes. They are designed to suit all applications and can fit into any wastewater pumping scheme where lifts of 4 to 5 ft (1.3 to 1.5 m) or less are required. They are ideal for pumping chemical floc, raw sewage, grit, primary sludge, return activated sludge, and mixed liquor.Airlift pumps Ovivo Water

Air Lift Pump Design Waste disposal & treatment Eng-Tips
Air Lift Pump Design. I have a situation where it it agvantageous to have an air lift inclined at (Approximately) 60 degrees from horizontal. The scenario is located in a wastewater clarifier, domestic sludge. In leu of cross bracing the tank, I was wondering how air lift pumps will perform at 30 degrees off vertical bracketed to the fillet.The authors recently designed and tested an experimental airlift unit that included a 7.9-cubic-meter circular fiberglass tank with 1.0 meter of water depth and a 0.14-cubmic-meter Polygeyser biofilter with enhanced media of 55 percent porosity. Water from the tank center drain gravity flowed to the filter through a 7.6-cm-diameter pipe.Airlifts combine pumping, water treatment in recirculation systems

The air lift pump consists of a riser tube immersed in the pumped liquid, a compressed-air line and a pressure chamber where air forces the liquid, via small holes into the riser tube, figure 3.52a. The air liquid mixture is lighter than the surrounding liquid and therefore rises up the tube. The flow of liquid up the riser tube3.5.2 Air lift pump Pumpfocus
