Abstract: (321 Views)
Background: The purpose of this study was to investigate the effect of using tubular settlers on the energy required for backwashing filters and the frequency of backwashing.
Methods: In this experimental study, two accelerator clarifiers connected to the raw water transfer channel No. 1 of the Isfahan Water Treatment Plant (WPT), Iran, were equipped with approximately 350 tubular settlers at an installation angle of 60 degrees.
Findings: The results of sampling the outlets showed that the average concentration of suspended solids in the clarifiers with tubular settlers was 3.20 ± 16.00 mg/l, while in clarifiers without tubular settlers, it was 4.41 ± 20.00 mg/l. The average removal efficiency of suspended solids in clarifiers equipped with tubular settlers was 64.86 ± 34.00%, compared to 52.10 ± 46.00% in other clarifiers. Additionally, the number of backwashing cycles of filters decreased by 25%, and energy consumption was reduced by 50%-60%.
Conclusion: The use of tube settlers to improve the quality of water entering filters reduces the number of backwashing cycles per day and ultimately saves energy for backwashing filters, which is very effective.
