Investigation of technical and economic benefits associated with the use of pure oxygen in the biological treatment of carbonization effluents

Cel

To impartially investigate the technical and economic benefits associated with the use of pure oxygen in the treatment of carbonization effluents.
Following the installation of a British Oxygen Company 'Vitox' pure oxygen injection system on the biological effluent treatment plant serving a UK coking works, the performance of the plant was closely monitored over an 18 month period and compared with the treatment performance achievable via conventional air-based effluent treatment.

The conversion from conventional surface aeration to pure oxygen injection coincided with a very dramatic improvement in effluent treatment performance at the works, part of the improvement being due to a general tightening-up over plant surveillance and operating discipline.

The BOC Vitox process proved to be a reliable and controllable means of providing mixing, sludge suspension and oxygen transfer in coke oven effluent treatment, however, at an oxygen consumption of 1.0-1.2 kg O2 per kg COD removed.

Reduced sludge wastage and antifoam requirement were obtained and the need to heat the aeration tank contents in winter months was totally eliminated. In addition C.O.D. removal proved to be 2-6% better than that achieved via conventional aeration and a less coloured final effluent was produced.
A pure oxygen injection unit (British Oxygen Company, 'Vitox' system) will be installed in the biological effluent treatment plant at a UK Coking works, with the full installation and operating costs of the unit being borne by the Monckton Coke and Chemical Company Limited.

Under financial assistance from the ECSC, the performance and economics of the modified effluent plant will be comprehensively monitored over a period of 15 months and will be compared with the performance and economics of the conventional effluent plant.

To ensure avoidance of any commercial bias in the study, an independent expert body (BCRA Scientific and Technical Services Limited) will oversee and assist in the investigation and will be responsible for producing a final report to the ECSC within three months of the monitoring programmes completion.
