Improvement of sedimentation process using inclined plates

Abstract EN

in this paper, study the effect of inserting inclined plates at angles (30o, 45o and 60o) at flow rate(0.5-2) l/min and detention time (200-50) min, with and without using an alum on the improvement of the turbidity removal efficiency( R) in an up flow settling tank compared without inclined plates, have been investigated by (PDS Sedimentation tank) for treating water from a water solution polluted by kaolinitic clay at initial concentration (360 mg/l ).The results indicate that the plates installed at the basin increased sediment turbidity removal efficiency to (87 %) at angle 30° when flow rate equal to (0.5) l/min, detention time (200 min) with using alum and (70 %) without using alum, compared without inclined plates, turbidity removal efficiency to (59 %) when flow rate equal to (0.5) l/min detention time (200 min) with using alum and (41%) without using alum.
