Abstract

A mathematical model for removing low-concentration suspension from raw water by dissolved air flotation method for drinking water is described. Methods The mathematical model is based on the known equations and dependencies of mass transfers. It takes into account the effect of the delayed bubbles on their rise velocity, as well as technological and design parameters. Results The numerical value of the flotation process constant has been obtained for waters with low concentrations of suspended solids. Scientific novelty The mathematical model which, for the first time, works with regard to the effect of bubbles delayed on rise velocity, as well as technological and design parameters such as water rise velocity, suspended solid concentration and particle size of containments, size of air bubbles and their concentration, is demonstrated. Practical significance The developed mathematical model enables in the future to study the design parameters of flotation tank and find the optimal dimensions with a high degree of clarification.
