Product Description

Introduction

Coagulation- flocculation - settling processes are generally used to separate colloidsfrom water, as in this case natural settling speed is too slow to obtain asufficient clarification. This plant enables to study the coagulation,flocculation and settling processes separately or simultaneously and it mainly consistsof a stirred feed tank, of two tanks for flocculent and coagulant, of a stirredcoagulation tank, of a stirred flocculation tank and of a plate settler.

Processcontrol, data acquisition and supervision are automatically carried out by a microprocessorcontroller and by a specific control and supervision software  that enables the remote control of variousoperational parameters.
