Title: Cake Filtration Characteristics of Date Paste-water Suspensions under Constant Pressure Conditions

Abstract: Pilot scale filtration of date paste-water suspensions at three concentra ons, namely, 1:1.5, 1:2, and 1:3 date paste to water ratios (w:w) were carried out at constant filtration pressures of 101.35 and 202.70 kPa (gauge). Two relevant mathema cal models from published works on filtration of food systems were slightly modified to account for the nonNewtonian behavior of date paste-water filtrates and the filtration system used. Filtration parameters were statistically determined using pilot scale experimental data and the two modified filtration models. Both models were adequate in describing the filtration behavior, however one of the models is physically more sound as it includes some of the important physical properties of suspension, filtrate, and cake. Filtration pilote de la suspension de patte des dattes mélange dans l'eau utilisant trois proporetions (p:p) de concentra on, 1:1.5, 1:2, et 1:3 a ete faite avec deux pressions de filtra on constantes de 101.35 et 202.70 kPa. Deux modeles mathema ques de travaux deja publies sur la filtration des systemes d' alimentation ont ete legerement modifier,tenant compte du caractere non-Newtenien des filtres et le systeme de filtration utilise. Les deux modeles ont ete adequats dans la descriptionde caractere de filtration. En effet, un des modeles est physiquement plus logique comme il indue quelque proprietes physique importantesde suspension, filtrage, et deposition solide.
