Coagulation Flocculation And Settling Pilot Plant Sewage Treatment Trainer Teaching Equipment

SRWT0015 Coagulation Flocculation And Settling Pilot Plant Sewage Treatment Trainer Teaching Equipment

1.Introduction

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. This plant 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. 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.

2.Training Program:

The process unit enables to develop and analyze the following issues:

coagulation

flocculation

co-current and counter-current settling

characteristics of coagulant and of flocculants

optimization of coagulation – flocculation and settling

Processes

automatic PID control

plant supervision
