Research on applying a water-lifting aerator to inhibit the growth of algae in a source-water reservoir
A new hydraulic, water-lifting aerator was developed for ameliorating water quality. It aims at mixing lower and upper water bodies, controlling algae growth, increasing dissolved oxygen concentration in water and inhibiting the release of pollutants from sediments. This new device was applied to control the algae growth in surface water of the water source of Tianjin. It was found that the content of agrology chlorophyll-a was reduced by 13.96%, and the growth of algae was inhibited. In this paper, the theory and application conditions of this new device for controlling algae are discussed.
