The efficiencies that can be obtained with low speed aerators depend on a number of factors. One important factor is the geometry of the basin in which the aerator will be installed. The Landy aerator can be installed in either a fixed or a floating arrangement. Regarding the geometry of the basins the options are virtually unlimited: square or rectangular tanks, round tanks, shallow or deep tanks, oxidation ditches, MBR- and SBR systems, lagoons, ponds, mixing or buffer tanks.
