Abstract

A mathematical model for deposit detachment and removal during the backwash of rapid gravity filters has been derived for a fluidising water wash. The model consists of two parts; part 1 determines the volume of deposit dislodged into suspension at any instant, and part 2 determines the change in concentration emerging from the filter bed at any stage during the backwash. Initial conditions for the backwash model are determined from a filtration model. © 1998 Published by Elsevier Science Ltd. All rights reserved.
