Abstract: There are many formulas that can be applied under field and laboratory conditions to determine the percent particle removal efficiency (PPRE). A lack of understanding of the limitations of each formula leads to improper ...

Abstract: It has been proven that the concept of using a high pressure water jet (HPWJ) to pretreat wastewater for the enhancement of ultraviolet (UV) disinfection of wastewater is an effective and cost-efficient alternative compared ...

Abstract: One of the greatest challenges faced when using gravity settling is achieving efficient particle removal and retention rates under high inflow rates. This paper proposes a new method for enhancing sedimentation and protecting ...

Abstract: The feasibility of high-rate treatment of storm water achieving total suspended solids (TSS) removals in the range from 60 to 80% was studied using an available clarifier. The clarifier (

Abstract: The performance of a combined sewer overflow (CSO) storage/treatment facility in North Toronto, Ont., Canada, was investigated by conjunctive numerical and physical (hydraulic) modeling. The main objectives of the study ...

Abstract: Often it is implied that hydraulic particle separators that incorporate vortex technology provide enhanced particle settling. In this study, a generic vortex particle separator was closely examined using physical modeling ...
