Description

This pilot plant consists of a reactor with built-in settler and floating head for hydraulic guard. Sludges are fed and recycled by two gear pumps; a compressor will recycle gas from the top to the bottom of reactor keeping biomass stirred. Biomass is heated by a heat exchanger included in the digester and connected with a diathermic-oil heating unit.
Process control, data acquisition and supervision are automatically carried out by a microprocessor controller and by a specific control and supervision software at enables the remote control of various operational parameters.

TRAINING PROGRAM:
The process unit enables to develop and analyze the following issues:
• Purification efficiency versus the following parameters:
- recycle ratio
- residence time
- digester temperature
- organic load
- pH and rH
• Automatic PID control
• Plant supervision

TECHNICAL CHARACTERISTICS:
• Framework of AISI 304 stainless steel with castors
• Feed tank with capacity of 700 l
• Anaerobic digester of AISI 316 stainless steel, with capacity of 350 l, equipped with oil heating system including a heat
exchanger of AISI 304 stainless steel
• Electronic thermostat for control of heating temperature
• Thermo-resistance Pt 100 with sheath of AISI 316 stainless steel
• Magnetic drive feed gear pump; body of AISI 316 stainless steel; flow-rate 0 to 60 l/h
• Magnetic drive sludge recycle gear pump with body of stainless steel AISI 316, flow rate of 0 to 60 l/h
• Diaphragm compressor with body of stainless steel, flow rate of 1200 Nl/h
• Electronic magnetic-induction feed flow rate transmitter of AISI 316 stainless steel, with range of 0 to 60 l/h and 4 to 20
mA output signal
• Board-type electronic indicator of feed flow rate, with range of 0 to 60 l/h
• Electronic magnetic-induction sludge recirculation flow rate transmitter of AISI 316 stainless steel, with range of 0 to 60
l/h and 4 to 20 mA output signal
• Board-type electronic indicator of sludge recirculation flow rate, with range of 0 to 60 l/h
• Microprocessor-controlled board-type pH-meter, with range of 2 to 12 pH, 4 to 20 mA output signal
• Microprocessor-controlled board-type rH-meter, with range of -1500 and +1500 mV, 4 to 20 mA output signal
• Pressure gauge with range of 0 to 50 mm H2O
• Pressure switch for controlling pressure in the reactor
• Switchboard IP55, complying with EC conformity mark, including plant synoptic and ELCB
• Emergency pushbutton
• Connecting lines and valves of AISI 304 and 316 stainless steel
• Power supply: 230 Vac 50 Hz single-phase - 1,5 kVA (Other voltage and frequency on request)

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
