A Perforated Baffle Design to Improve Mixing in Contact Tanks

Design and Performance of Chlorine Contact Tanks

Most existing chlorine contact tanks suffer from serious drawbacks of dead spaces, short circuiting, and solids accumulations that subsequently putrefy and exert undue chlorine demand. Hydraulic model studies of chlorine contact tanks indicate that air agitated, baffled contact units have better flow characteristics than just baffled units or air agitated contact tanks without baffles. Air agit...

A Systematic Approach to the Design of Buffer Tanks

Buffer tanks are often designed and implemented for control purposes, yet control theory is rarely used when sizing and designing buffer tanks and their control system. Instead, rules of thumb such as using “10 min residence time” are used. The objective of this paper is to provide a systematic approach. We consider mainly the case where the objective of the buffer tank is to dampen (“average o...

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

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 ...
