AFW015 Coagulation Flocculation And Settling Pilot Plant Teaching Equipment Educational Coagulation Flocculation Training Equipment
INTRODUCTION
Coagulation - fl occulation - settling processes are generally used to separate colloids from water, as in this case natural settling speed is too slow to obtain a suffi cient clarifi cation.  This plant enables to study the coagulation, fl occulation and settling processes separately or simultaneously and it mainly consists of a stirred feed tank, of two tanks for fl occulant and coagulant, of a stirred coagulation tank, of a stirred fl occulation tank and of a plate settler. Process control, data acquisition and supervision are automatically carried out by a microprocessor controller and by a specifi c control and supervision software that enables the remote control of various operational parameters.

TRAINING PROGRAM:
The process unit enables to develop and analyze the following
issues:
coagulation
fl occulation
co-current and counter-current settling
characteristics of coagulant and of fl occulants
optimization of coagulation – fl occulation and settling
Processes
automatic PID control 
plant supervision
