Hydrodynamic Design and Assessment of Water and Wastewater Treatment UnitsAuthor(s): Edmilson Costa Teixeira, William Bonino Rauen\nFormat: Hardback\nPublisher: Taylor & Francis Ltd, United Kingdom\nImprint: CRC Press\nISBN-13: 9781138495890, 978-1138495890\nSynopsis\nWater and wastewater treatment normally take place in a series of continuous flow units, each designed to perform a step of the intended purification process - typically involving coagulation or flocculation, sedimentation or filtration, and disinfection. The flow pattern governs the residence/contact time, turbulence levels, collisions and shear to which different fluid portions are subjected in their passage through the unit. The efficiency of a given unit depends as much on the relevant physical, chemical or biological reaction as on the flow pattern taking place inside. This combined effect of flow features on process efficiency is often overlooked in teaching the design of water and wastewater treatment units, .
