Abstract

One of the problems associated with the sub-surface water intake systems is the sediment inflow control, which is usually solved by a filtration system. Geotextile filter is one of the filter types for controlling sediment in the subsurface water intakes. In this research in order to investigate the capability of geotextile filter for filtration of water through the sub-surface vertical pipe intake, various experiments with different arrangement of the geotextile were carried out in a flume with the height of 1.2 m, width of 0.5 m and a length of 5 m, located in Soil Mechanics Laboratory of Shahrekord University. Based on the dimensional analysis, the effective parameters on the discharge capacity and the filtration efficiency were identified. The results showed that the different arrangements of the geotextile filters (laminated and rolled geotextile sheets) did not show a significant impact on flow capacity of the system. The results also showed that the sediment trap efficiency for rolled geotextile sheets was obtained 60 to 70 percent but it was about 80 to 90 percent for the laminated geotextile sheets. It indicates that the laminated geotextile sheets controlle the sediment by 36.6% more than the rolled geotextile sheets.
