Abstract

The presence of algae in WSP effluent could be a problem if the effluent is to be discharged to natural water bodies, or for reuse, as is now being experienced by Bolivar WSP. Non-chemical-cost effective means are perceived to be preferable for long-term scheme. Therefore, biological and physical approaches have been investigated, including modification of the existing WSP geometry and inlet and outlets structure using Computational Fluid Dynamics (CFD). Inputs for modeling the hydraulics of the pond are flow rate and geometry of the pond, including inlets and outlets, whereas algae are assumed as suspended solid particles that behave like sediment with certain size and settling rate. Eight pond models with different geometry configurations were run to predict the flow pattern within the pond using FLUENTTM. Model #1 result in longest Retention Time but particle tracking shows that the lowest particle concentration is found in Model # 3 with Outlet Type B, that could be induced be the plug flow pattern. Inlet type, however, does not have a significant impact on settlement of particles, probably due to small inlet momentum compared to the size of the pond.
