Sedimentation Control Using Two Baffle Boxes in Series

Investigating the effect of flow entrance and existence of baffle on sedimentation efficiency using Discrete Phase Model (DPM)

Presence of salts in water has been one of the biggest problems of industrial equipment such as evaporators, boilers, and pipes. These salts gradually form scales on evaporators and boilers tubes and reduce their efficiency. Pretreatment processes are conducted to remove these salts; with sedimentation tanks being one of the essential equipment used in these processes. This study numerically si...

A CFD methodology for the design of sedimentation tanks in potable water treatment Case study: The influence of a feed flow control baffle

Computational fluid dynamics simulations are employed to assess the effect of adding a vertical baffle at the feed section of a full-scale edimentation tank for the improvement of solids settling in potable water treatment. A general CFD-based simulation strategy is developed based n the specific features and conditions met in practice for potable water treatment. The linearity of the particle ...

Experiments and numerical modeling of baffle configuration effects on the performance of sedimentation tanks

Numerical Modeling of the Effect of the Baffle Location on the Flow Field, Sediment Concentration and Efficiency of the Rectangular Primary Sedimentation Tanks

In order to increase the performance of a primary sedimentation tank (clarifier), it is essential to have a uniform and calm flow field. The use of suitable baffle configurations may help forming favorable flow field and increase the efficiency of the primary sedimentation tank. In order to find the proper position of a baffle in a rectangular primary sedimentation tank, computational investiga...

Jets Opposing Turbidity Currents and Open Channel Flows

Hydraulic jumps at the tail end of spillways are usually induced by baffle blocks or other obstacles. Such jumps can also be induced by jets that oppose the main flow. Another application is to back up turbidity currents in reservoirs by means of opposing jets. This measure can be adopted when transfer tunnels feed water into the reservoir at a higher elevation near the dam. Stopping the turbid...
