Coagulation, Flocculation and Settling Pilot Plant ENV 014
Coagulation, Flocculation and Settling Pilot Plant ENV 014
Coagulation – flocculation – settling processes are generally used to separate colloids from water, as in this case natural settling speed is too slow to obtain a sufficient clarification. Sci-tech Coagulation, Flocculation and Settling Pilot Plant Model ENV 014 enables to study the coagulation, flocculation and settling processes separately or simultaneously and it mainly consists of a stirred feed tank, of two tanks for flocculant and coagulant, of a stirred coagulation tank, of a stirred flocculation tank and of a plate settler.
Item Description
Process control, data acquisition and supervision are automatically carried out by a microprocessor controller and by a specific control and supervision software that enables the remote control of various operational parameters.
