FILTRATION PILOT PLANT.

INTRODUCTION

This fi ltration plant mainly consists of a sand fi lter and of an
activated carbon fi lter; fi ltered water is collected into a tank
of stainless steel from which samples for proper laboratory
analyses can be extracted. An in-line turbidimeter enables to
measure the turbidity of water fl owing in and out of fi lters.
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:
• mechanical filtration
• chemical fi ltration
• main parameters affecting fi ltration
• infl uence of feed fl ow rate on fi ltration
• automatic PID control
• plant supervision (only for
