AbstractLiterature reports rather contradictory results regarding the performance of dual media filters with an intermixed zone. However, one common point to which all researchers have agreed is that the size ratio of anthracite to sand grains is the primary factor responsible for intermixing. Though many theoretical formulations exist to determine the size ratio of anthracite to sand grains which cause mixing there is no specific means to quantify the degree of mixing with variation of size ratio. This study apart from suggesting a method of quantifying the degree of mixing, also attempts to determine the effect of intermixing on effluent quality and headloss development. A mathematical model has been formulated to explain the observed experimental results.
