Comparison of Water-Lifting Aerator Type for Algae Inhibition in Deep Reservoirs

Abstract:

Water-lifting aeration technology is one of the effective in-situ algae control technologies in deep reservoirs. Effects of water-lifting aerator type on the in-situ algae inhibition using water-lifting aeration technology was numerically analyzed with the help of FLUENT software. Under stable state, one large clockwise circulation flow was generated outside non-submerged and submerged water-lifting aerators, but the core algae inhibition zone was farther away from the non-submerged aerator under each water depth. When the water depth was increased from 77.25 m to 97.25 m, the percentage of the core algae inhibition zone to the whole flow domain was decreased from 56.01% to 47.34% for the submerged water-lifting aerator case, while that was decreased from 55.48% to 40.15% for the non-submerged water-lifting aerator case.
