Abstract
Floating garbage in a filtration system is one of the main factors causing many problems in engineering structures because the accumulation of garbage can block the flow rate. The bar screen installed in a water channel is used to catch the garbage, but the main threat when installing a bar screen in a water channel (intakes) is that system can lead to headloss and disturb (block) fluid flow occurrence. However, there is no concern about the effect of garbage level on the bar screen to head losses and water discharge; for the filtration system, the main concern is discharge. Therefore, this study aims to investigate the effect of garbage level on bar screens to head losses and water discharge by the computational fluid dynamics (CFD) method. Based on the results, the CFD method is capable of predicting the headloss and discharge for the filtration system in the channel. However, the headloss that occurred was insignificant (as still normal) and can reduce the water discharge from the inlet by more than 45%. Then, water energy dissipation due to the narrowing of the flow field consequence of the blockade of garbage. Then, estimating discharge in a filtration system connected to the high seas requires tidal analysis because tides affect the headloss and the water discharge. Further, the headloss is directly proportional to the flow speed and the channel's width.
