    The coagulation-flocculation process consists of rapid mixing, followed by slow mixing and settling at room temperature. Efficiency of coagulation-flocculation process depends on process :// Coagulation is a chemical process that involves neutralization of charge whereas flocculation is a physical process and does not involve neutralization of charge. The coagulation-flocculation process can be used as a preliminary or intermediary step between other water or wastewater treatment processes like filtration and ://

Coagulation is performed in two stages: first the coagulant is rapidly mixed and then flocculation is enhanced by slow mixing. Hence, the optimized dosages were further optimized for varied mixing speed and time for each stage of ://

Thoroughly revised and updated this new edition has been progressively modified and increased in scope to cater for the requirements of practitioners involved What is Flocculation in Water Treatment? Flocculation is the phase that occurs after flash mixing. During this phase, the particles to be removed from water are brought to larger agglomerations, called flocs, in order to settle down in the sedimentation chamber and be easily happens thanks to the reaction with a polymer solution, which acts as flocculant ://

As used in this book, coagulation involves the data /lectures. Water supply system - Water supply system - Coagulation and flocculation: Suspended particles cannot be removed completely by plain settling.

Large, heavy particles settle out readily, but smaller and lighter particles settle very slowly or in some cases do not settle at all. Because of this, the sedimentation step is usually preceded by a chemical process known as :// Rapid mixing process At pH levels aboveparticles or molecules are generally negatively charged.

The coagulation process physically occurs in a rapid mixing process. Mixing is commonly referred to as flash mixing, rapid mixing, or initial mixing. The purpose of rapid mixing is to provide a uniform dispersion of coagulant chemical Orthokinetic flocculation is the mechanism in solution which attracts and bridges colloids in order to create flocculation.

Mixing induces velocity gradients that cause micro-flocs to agglomerate and form bigger flocs. The rate of flocculation is controlled by velocity gradient applied during mixing, or by how many of the polymers approach or   Buy Coagulation and Flocculation in Water and Wastewater Treatment 3rd Revised edition by John Bratby (ISBN: ) from Amazon's Book Store.
