Dimensional Analysis Model of Head Loss for Sand Media Filters in a Drip Irrigation System Using Reclaimed Water

A new model was developed to predict head loss in sand media filters. Sand filters with six different using reclaimed water were used measure losses at flow rates the laboratory. The parameters influencing considered be uniformity coefficient, effective diameter, mass, filtration velocity, pollution load, and viscosity. dimensional analysis method develop model. comparison between predicted measured showed close agreement a correlation coefficient of 91.7%, reaching significance level p < 0.001. results that might give satisfactory predictions within following range operational filter structure parameters: 1.48–3.31; diameter 0.41–2.1 mm; load 0.0169–4.2049 kg, velocity 0.0038–0.0398 m/s.
