This program evaluates mass balances in a counter-current washing train with up to 20 stages. It is primarily designed for re-slurry washing such as with gravity thickeners or hydrocyclones (the displays refer to hydrocyclones specifically) but it may also be applied to displacement washing on horizontal belt filters, for example. It is immaterial whether it is solubles or ultrafine particles that are to be washed off the solids.
The program assumes complete mixing, in each stage, of the forward and returning flows and also complete mass transfer from the solid particles into the suspending fluid. It can, however, include the effects of solubles entering with the wash liquid and also of the wash liquid entering with the solids. The two options offered include the following:
Both options allow printing of the balances, amendment of the feed data and simultaneous display of the old balances with the new ones, and plots of the feeds, underflows and overflows along the train for both the wash liquid and the solubles flows.
