SRWT0015 Coagulation Flocculation And Settling Pilot Plant Teaching Equipment Sewage Treatment Trainer
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 followingissues: 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 3.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 of300 l Feed tank of transparent methacrylate for coagulant with capacity of 60 l Feed tank of glass for fl occulant, 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 fl ow 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 fl ow rate of 0 to 200 l/h Electronic frequency variator for screw pump Gear feed pump of AISI 316 stainless steel for coagulant, withfl ow-rate of 0 to 50 l/h Metering pump of flocculant, with fl ow rate of 0 to 200 ml/h Switchboard IP55, complying with EC conformity mark, including plant synoptic and ELCB Digital microprocessor PID controller, with two control loops Supervision software for Windows: it enables to control ONOFF signals, analog signals coming from PID controller, realtime trend and historical trend Dimensions: 1800 x 800 x 2700 mm,Weight: 300 kg.Supplied:THEORETICAL – PRACTICAL –EXPERIMENTAL HANDBOOK
