This work focuses on the conception and formulation of appropriate filtration models for
use by water treatment professionals for design, development and management of deep-bed (depth)
filters. Performance and optimization studies were carried out using data (turbidity, filtration rate,
head loss) acquired from pilot filter test runs. The curves developed from these studies were utilized
for the formulation of steady-state and hydro-dynamic models of depth filtration. An effluent
quality model was developed, relating depth of flow in filter bed with effluent turbidity. This model
was verified and validated. The depths obtained are in good agreement with standard values from
literature.
