SRWT0014 Filtration Pilot Plant Educational Equipment Sewage Treatment Trainer
1.Introduction This filtration plant mainly consists of a sand filter and of an activated carbon filter; filtered 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 filters.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 operationalParameters 2.Training Program: The process unit enables to develop and analyze the following issues: • mechanical filtration chemical filtration main parameters affecting filtration influence of feed fl ow rate on filtration automatic PID control plant supervision (only for 3.Technical Characteristics: Framework of AISI 304 stainless steel with castors Sand filter of borosilicate glass with decresing particle size and capacity of 30 l Activated carbon filter of borosilicate glass with capacityof 30 l 4 pressure gauges, with range of 0 to 10 m of water column Centrifugal pump with casing and rotor of AISI 304 stainless steel and fl ow-rate of 3000 l/h Variable area flowmeter of AISI 304 stainless steel, with range of 100 to 1000 l/h Metering pump of plastic material for sodium hypochlorite, with fl ow rate of 3 l/h Metering pump of plastic material for flocculant, withflow-rate of 3 l/h 2 feed tanks of AISI 304 stainless steel with capacity of 120 l Tank of AISI 304 stainless steel for collecting the filtered water with capacity of 200 l Thermoresistance Pt 100 with sheath of AISI 316 stainless steel Board-type electronic temperature indicator Switchboard IP55, complying with EC conformity mark, including plant synoptic and ELCB Connecting lines and valves of AISI 304 and 316 stainless Steel Pneumatic control valve of stainless steel AISI 316 for feed fl ow rate of water, Cv = 2.5 Electropneumatic converter (4 to 20 A / 0.2 to 1 bar)• Electronic turbidimeter formeasuring the turbidity of the water fl owing in and out of filters, with programmable range and 4 to 20 mA output signal 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.Power supply: 230 Vac 50 Hz single-phase - 1,5 kVA.(Other voltage and frequency under request).Dimensions: 2150 x 750 x 2000 mm,Weight: 460 kg,Supplied THEORETICAL – PRACTICAL – EXPERIMENTAL HANDBOOK
