In coagulation, chemicals are added to water in order to gather unwanted particles/matter into flocs that can be then removed, for example using sand filtration. Coagulation is used for the removal of organic matter and suspended solids from raw water, for example.
Equipment and system principle
Systems consist typically of a chemical dosing unit (coagulant and flocculant) and a coagulation tank/vessel.
Required information for system design
To complete a water treatment system design, a raw water analysis is needed together with information about the required water flow/capacity of the system and the required water quality after treatment/use of the water produced. If the equipment is being installed in an existing space, information about the available drainage and room dimensions is also good to know.
