Description

The activated sludge pilot plant consists of an oxidation reactor and of a settler according to the traditional diagram of single stage sewage treatment process. Biomass is oxidized in a reactor with agitator by the air blown by a compressor. The processed liquid is sent to the settler through an overflow. The sludges settling at settler bottom are recycled by a recycle pump into the oxidation tank.

TRAINING PROGRAM:
The process unit enables to develop and analyze the following issues:
• Purification efficiency versus the following parameters:
- composition of water under to be treated
- residence time
- organic load
- pH in oxidation tank
- concentration of dissolved oxygen

TECHNICAL CHARACTERISTICS:
• Framework of AISI 304 stainless steel with castors
• Feed tank with capacity of 300 l
• Cylindrical oxidation reactor of AISI 304 stainless steel, with capacity of 60 l, including an inspection window of transparent methacrylate and three overflows at different heights to vary reactor volume.
• Agitator of AISI 304 stainless steel with geared motor
• Settler of AISI 304 stainless steel, with capacity of 30 l, provided with inspection window of transparent methacrylate
• 2 magnetic drive gear pumps (for feeding and recirculation), with body of AISI 316 stainless steel, flow-rate 0 to 60 l/h
• Air compressor with body of stainless steel, flow rate of 1.5 Nm³/h
• Air diffuser of AISI 316 sintered stainless steel
• 2 magnetic-induction flowmeters (for feeding and recirculation) with range of 0 to 60 l/h and 4 to 20 mA output signal
• Flowmeter for measuring air flow rate to oxidation reactor, with micro-valve; range of 0 to 180 Nl/h
• Thermo-resistance Pt 100 with board-type digital temperature indicator
• Microprocessor-type electronic dissolved oxygen indicator transmitter, with range of 0 to 10 ppm
• Microprocessor-type electronic pH indicator-transmitter, with range of 0 to 14 pH
• Digital indicator of feed flow rate
• Digital indicator of sludge recycle flow rate
• Connecting lines and valves of AISI 304 and 316 stainless steel
• Switchboard IP55, complying with EC conformity mark, including plant synoptic and ELCB
• Power supply: 230 Vac 50 Hz single-phase - 1 kVA (Other voltage and frequency on request)
