Evaluation of nanobubble technology for the reduction of suspended solids and turbidity in Lake Amatitlán, Guatemala

MOJ Ecology & Environmental Sciences
Nelson Sebastian Escobar Reyes


Lake Amatitlán in Guatemala is in accelerated process of contamination and artificial eutrophication, having a high amount of suspended solids, these cause the appearance of the water to be turbulent. The purpose of the research was to evaluate the ability of oxygen nanobubble technology to minimize all particulate matter and reduce turbulence. The investigation consisted of taking a sample of 33 m³ of water with a high organic load and cyanobacteria, Microcystis aeruginosa. Oxygen nanobubble was applied for eight days operating two hours and 45 minutes per day, making a total of 19 hours. Six samples were obtained, the first was the control sample. The results obtained were favorable with a recorded reduction of suspended solids from 73.39% to 64.05%. The final results were compared with quality standards of oligotrophic algos from Mexico and Peru.
