Abstract
Jet loop Bioreactors (JLBR) are being widely applied in a number of chemical, Biochemical, Petroleum refineries and Petrochemical industries for the treatment of the waste water. Some of the advantages of the system are simple in construction& operation, low investments& operational cost as well as very fine gas dispersion and high mixing& mass transfer performance. In JLBR circulation and fluid dispersion are achieved by a liquid jet. Liquid is injected into the reactor with high velocity causing a fine dispersion of different phases. In down flow jet loop reactors the driving gas is introduced from top of the reactor into a liquid flowing co currently downward so that the gas bubbles are forced to move in a direction opposite to their buoyancy. The reactor consists of a vertical column. A draft tube was placed axially in the centre of the reactor. The spray nozzle is located inside the draft tube. Mixing Characteristics in JLBR will be studied by using conductivity cell with the tracer particle or Photographic techniques. To study of the hydrodynamic behavior of fluid flow inside the reactor, effects of various parameters like liquid flow rate, gas flow rate Nozzle diameter, Nozzle heights etc on mixing characteristics are planned to study.
