Description

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.

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

TECHNICAL CHARACTERISTICS:
• Framework of AISI 304 stainless steel with castors
• Cylindrical feed tank of transparent methacrylate for the water to be treated with submersible pump and capacity of
300 l
• Feed tank of transparent methacrylate for coagulant with capacity of 60 l
• Feed tank of glass for flocculant, provided with hot-plate magnetic stirrer, with capacity of 0.5 l
• Coagulation reactor of borosilicate glass, equipped with motor-driven stirrer (0 to 300 r.p.m.), with capacity of 30 l
• Flocculation reactor of borosilicate glass, equipped with motor-driven stirrer (0 to 100 r.p.m.), with capacity of 8 l
• Rectangular settler of transparent methacrylate with conical bottom and movable plates for its operation in co-current
and counter-current
• Flowmeter of AISI 304 stainless steel for measuring feed flow rate with range of 30 to 300 l/h
• Flowmeter of coagulant feed with range of 2 to 20 l/h
• Feed screw pump with casing and screw of AISI 316 stainless steel and flow rate of 0 to 200 l/h
• Electronic frequency variator for screw pump
• Gear feed pump of AISI 316 stainless steel for coagulant, with flow-rate of 0 to 50 l/h
• Metering pump of flocculant, with flow rate of 0 to 200 ml/h
• Switchboard IP55, complying with EC conformity mark, including plant synoptic and ELCB

Besides being provided with all the technical characteristics, this model also includes the following additional equipment:
• Digital microprocessor PID controller, with two control loops
• Supervision software for Windows: it enables to control ON/OFF signals, analog signals coming from PID controller, real time trend and historical trend.
