Hydrodynamic design of water and wastewater treatment units

Water 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/conta...
