Anaerobic Digester

Product Code : EL-ELE-17589

• A benchtop anaerobic digester for wastewater treatment studies

• Equipped with two 5l packed bed, upward-flow reactors

• Each reactor has gas sampling & collection facilities

• Reactors may be operated in series or parallel flow arrangement, using variable-speed peristaltic pumps

• Feed flow rate to each reactor can be accurately and independently controlled to any temperature between ambient and 55°C, using 200W heating jackets

• Thermostatic cut-out set to 110°C

• An instruction manual describing test and practical work capabilities, including details of a proven feedstock (synthetic wastewater) is included

• Reactors: Two, identical -Nominal capacity: 5 liters -Packed volume: 4 litres 150mm diameter x 250 mm height

• Reactor packing: 25mm diameter Bio-balls

• Temperature control: For each reactor: 200W heating jacket with PID control from a temperature sensor positioned inside the reactor, set point within range ambient to 55°C, the jacket is thermostatically protected by a cut-out set at 85°C

• Feed pumps: Two identical peristaltic pumps: variable speed using 10 turn potentiometer to 4rpm supplied with three tube diameters, 1.6, 3.2 and 4.0mm, flow rates from 0.2 to 5.8 L/day

• Gas collection vessels: Two, identical - linear scale, 0-5 liter capacity
