Prediction Of Rapid Sand Filtrate Concentration

Abstract
Rapid sand filtration is an essential process in purification of
water. Then, in order to operate the rapid sand filter according
to the time variation of the influent and effluent concentration,
a simple and physically meaningful mathematical model, which
contains one unknown parameter to be estimated adaptively during
the operation, has been constructed. The filtrate quality was
simulated using a dynamic parameter estimation method based on
the quasi-linearization of the model equations. The comparison
of the Eliassen's experimental values with their simulated ones
shows that the prediction procedure combining with the model
may be practical for the operation of rapid sand filters.
