Abstract
On the basis of empirical data the approximation of settling curve h=f(t) for various initial concentrations of the coal sludge flotation concentrate and coal tailings suspension was done in the paper, where t - time of settling, h -way passed by the suspension. The experiment was conducted for both cases with use of bioflocculant and without it. The bioflocculants were, in various doses, activated sludges originating from municipal sewage treatment plant. Such functions as exponential, logarithmic or rational ones were used to conduct the approximation. The evaluation of fitting was done by means of mean squared standard error. On the basis of obtained functions describing settling curve the settling velocity was determined as v(t)=f’()and velocity was calculated as, where Δ is maximum time of settling. The determined settling curves were the basis to investigate relation between settling velocity and initial concentration as well influence of applied bioflocculants on settling velocity. The evaluation of influence of bioflocculants sort on efficiency of mineral suspensions settling was done.
