BE4 Anaerobic Column Reactor

 

BE4 Anaerobic Column Reactor

The reactor on BE4 is a cylindrical glass vessel with a water jacket for heating. The vessel is supplied with baffles and a variable-speed stirrer for use as a continuous stirred tank reactor (CSTR).

Multi configurable and extremely versatile for both educational and research purposes. It has a self-contained, floor-standing anaerobic tank reactor, Volume 20 litres, stirrer, motor and baffles are removable for non-stirred configurations.

Description

The reactor on BE4 is a cylindrical glass vessel with a water jacket for heating. The vessel is supplied with baffles and a variable speed stirrer for use as a continuous stirred tank reactor (CSTR).
The baffles and stirrer are removable to enable the reactor to be filled with bio-balls and a support grill, to reconfigure the unit as a packed bed reactor.
An alternative reactor lid complete with deflector and tri-phase separator is also supplied. This enables the reactor to also be configured as an upflow anaerobic sludge blanket reactor (UASB).

The feed into the reactor is provided by a variable-speed peristaltic pump. The lid of the reactor is fitted with a sampling station, which includes ports for instrumentation probes (both temperature and pH) and permits liquid samples to be taken from the reactor at different depths.
The reactor temperature is controlled by a recirculating water system in the same way as the BE3 and the same novel system for collecting and measuring the emitted gas is used. Similarly the pH dosing system is identical in concept and the data can be recorded on a PC using the data logger.

Technical Specifications

Features & Benefits

  • Continuous stirred tank reactor (CSTR)
  • Packed bed reactor (PBR)
  • Upflow anaerobic sludge blanket reactor (UASB)
  • Measures reactor temperature, jacket temperature and vessel pH
  • Programmable logic controller (PLC) provides temperature control, pH control and gas collection (rate and totalisation) calculations
  • Jacket heating system with pump and hot water vessel. Temperature is PID controlled room temperature to 55°C
  • Automated volumetric gas collection system measures, which adds less than 10 mbar back pressure to the reactor
  • Complete with automated pH dosing system to maintain the vessel pH within a predetermined range (user programmable)
  • User calibration of pH and gas collection system
  • Feed flow rates from 0.06-4.8 l/hr (using interchangeable peristaltic hoses)
  • Gas sample point
  • Data logger and software as standard (requires PC, not supplied)

Electrical supply:

220-240V / 1ph / 50Hz / 10 amp
220V / 1ph / 60Hz / 10 amp

Water and drain:

The reactors need to be connected to a supply of water (>1 bar) and to a suitable drain.
The amount of fresh water used during the operation of the BE3/BE4 will be the same as that of the gas produced.

Ventilation:

The gas produced can be collected (vessel not provided) or can be vented to atmosphere. In any case the reactors should be positioned in a well ventilated area, and an outlet provided to vent the emitted gases outdoors.

Computer:

A Windows PC (not supplied) running Windows XP or later, with USB port is required if running the data logging software.
