Development of a classifier system for the treatment of process and effluent streams

The paper describes the development of a flexible system for the pre-treatment of process and effluent streams. Incorporating both a cyclone separator stage, and a recovered product dewatering stage, the system has a number of possible modes of operation. Depending on the requirements of individual applications, it could be regarded as a solids recovery system, a fluid recovery system, or as a solid-solid separator/concentrator system. The implications of each of these potential applications are addressed. The results of a series of preliminary trial studies, focusing on the characterisation of the cyclone separator stage are presented. By means of adjusting various parameters, it is demonstrated how the output of the unit can be varied and controlled, indicating its potential scope for application in the industrial effluent and processing scene.
