Automation Aspects of Wastewater Treatment Plant Design and Operation
This paper provides primarily a discussion of the instrumentation, control and automation aspects of improving the efficiency of certain wastewater treatment facilities including control and operation of sewerage systems, primary and secondary sewage treatment and sludge handling and disposal. Relevant aspects of the activities of the recently constituted IAWPRC's Instrumentation Group receive brief mention including its activities in the areas of evaluation of existing sensors and systems, their relevance to particular needs, attributes and deficiencies, and also in the area of promotion of relevant research and development. A brief appraisal and description of existing sensors and systems, an indication of their usefulness to date and details of alternative instrumentation configurations for use in the enhancement of their general utility is provided. Relevant research and development is reviewed, including relevant remote sensing aspects, and developments in micro electronics and computing: finally some new horizons are explored.
