Reduction of COD and TSS of waste effluents from a sugar industry through the use of air micro-nanobubbles

Milagros Leyva, Jhonny Valverde Flores

Abstract


The sugar industry uses large volumes of water for its production process. The discharge of effluents is one of the main problems that affects mainly rivers, seas, resulting in the high level of pollution that captures plant and aquatic life. The objective of this research is to reduce the concentration of Chemical Oxygen Demand and Total Suspended Solids by treating air nanobubbles. The experiment was carried out with a sample of sugar process effluent having as the initial concentration value of the Chemical Oxygen Demand of 412.15 mg O2/L. and Total Suspended Solids of 620 mg TSS/L. After treating the water in a time of 90 minutes it was obtained as final result the Chemical Oxygen Demand was 66.13 mg O2 /L and Total Suspended Solids 131 mg TSS/L, improving water quality as well as for reuse for another type of use.
