Abstract
A mathematical model for deposit detachment and removal during the bac kwash of rapid gravity filters has been derived for a fluidising water wash. The model consists of two parts; part 1 determines the volume o f deposit dislodged into suspension at any instant, and part 2 determi nes the change in concentration emerging from the filter bed at any st age during the backwash. Initial conditions for the backwash model are determined from a filtration model. (C) 1998 Published by Elsevier Sc ience Ltd. All rights reserved.
