Abstract

The experimental work was carried out at Ismalia wastewater treatment plant in "Serapeurn". For the last 35 years in the field of wastewater filtration, many new models of filters were used Some types use upward flow filters such as filters with floating granular media from expended polystyrene. They have many advantages over other types that have high holding capacity. The applied filters contain floating media for physically and biologically treating municipal wastewater of Ismalia City for reuse in agriculture. The experiment was set for the comparison between the granular and crushed foam with effective diameter 1.6 — 2 mm and 2 — 3 mm re­spectively. The data showed that the granular foam media was more effi­cient in the removal efficiency measured as TSS mg/L, VSS mg/L, BODY mg/L, F. Coliform N/100 ml and Chlor (A) which increased by percentag­es of 16.2, 20.8,2.7, 18.5, and 6.1, respectively than those of the crushed one, at head losses of 0.3 bar. All hydraulic parameters (flow rate reduction as percentage, time consumed for filtering in cubic me­ters, mean flow rate and filtration cycle time) related to removal efficien­cy were in general better in granular media under different inlet pres­sures (2.0 bar and 1.0 bar) and those under 2.0 bar inlet operating pressure were better than those under 1.0 bar. The filtration cost of granular media was 0.0024LE under inlet operating pressure of 2.0 bar.
