Baffle plate configurations to enhance separation in horizontal primary separators

A CFD methodology for the design of sedimentation tanks in potable water treatment

“…Moreover, Lyn et al [13], based on model observations, concluded that for conditions of relatively small particles concentrations in sedimentation tanks, the flocs coalescence do not affect the flow field and the effects on the concentration field and the removal efficiency may be of secondary importance. Finally, drops in the size range relevant to primary separators do not suffer breakage [18].…”

Experimental and Computational Analysis on Influence of Water Level on Oil-Water Separator Efficiency

“…The primary stage of this separation process has traditionally been performed by large horizontal cylindrical gravity settling vessels [10]. In order to enhance both operational safety and economic performance, it is necessary to reduce separator size without losing separation effectiveness [11]. To diagnose operational inefficiencies and identify design improvements, a good understanding of the flow and separation behavior within the separator is crucial, which can be conducted by computational fluid dynamic (CFD) simulation and interpreting the vessel residence time distribution [12].…”

Experimental and Computational Investigations of Baffle Location Effect on the Performance of Oil and Water Separator Tanks

“…This situation allows oil droplets to coalesce with other droplets and to rise rapidly toward the separator surface. The effectiveness of baffle location in improving the uniformity of the flow pattern has been assessed by comparing the standard deviation (SD) of x-velocity across the cross section [10]. For each baffle location case, the axial velocity is retrieved at 82 equally spaced points along five vertical positions in the separator tank, and then, the SD is calculated.…”
