Editing Flocculation (section)

=== Jar test ===
The process by which the dosage and choice of flocculant are selected is called a jar test. The equipment used for jar testing consists of one or more beakers, each equipped with a paddle mixer. After the addition of flocculants, rapid mixing takes place, followed by slow mixing and later the sedimentation process. Samples can then be taken from the aqueous phase in each beaker. <ref>{{cite book |author=<!--Staff writer(s); no by-line.--> |date=2011-06-01 |title=Operational Control of Coagulation and Filtration Processes (M37): AWWA Manual of Practice |url= https://engage.awwa.org/PersonifyEbusiness/Store/Product-Details/productId/6726|publisher= American Water Works Association|isbn=978-1583218013}}</ref>
