Abstract
The tendency to concentrate exclusively on filter process parameters and not generally according due importance to suspension properties is one of the major causes of the lack of ability to predict filter effluent quality. This research shows that a particle size distribution function can serve as a much more effective and reliable index in filtration than the commonly used 'average' particle diameter. The power-law function is found to serve as a good expression of particle size distribution (PSD) and experimental results demonstrate its validity. The function is used to develop a new model based on the Kozeny equation, predicting head loss in the filter working stage using only filter effluent PsD function parameters and a transformation equation derived for prediction of filtrate PSD.
