The paper examines the importance of size distribution of the influent
suspension on the performance of deep bed filters and its significanc
e with regard to modelling. Experiments were carried out under a varie
ty of conditions using suspensions which were identical in every respe
ct apart from their size distribution. The results indicate that the p
resence of coarse particles does increase the removal of fine particle
s. Deposition of fine particles leads to a greater headloss than depos
ition of large particles. Changes in size distribution with time and d
epth play an important role in determining the behaviour of a filter,
and models of both removal and headloss development must take account
of this.
