Abstract

Circulation regions always exist in the settling tanks. These regions reduce the tank's performance and decrease effective volume of the tank. Recirculation zones would also result in short-circuiting and high flow mixing problems. Inlet position would have an effect on these, too. Use of good baffle configuration may increase performance of settling tanks. One method for comparison performance of different tanks with each other is to use flow through curves (FTCs). In this note using FTCs, effects of inlet position and baffle configuration on the hydraulic performance of primary settling tanks are studied. The best position of baffle is also determined.
