| Contents Notes |
Field, laboratory, theoretical, and state-of-the-art studies were conducted with regard to use of microscreens for tertiary sewage treatment applications. Field studies were conducted with two pilot microscreen units, using a variety of screen sizes and types, for activated sludge, trickling filter, and oxidation pond effluents. Particle size distribution of the effluents (microscreen influents) were found to be the key characterizing parameter in determination of treatment effectiveness. Overall effectiveness of solids removal was low, and was ascribed to deficiencies in microscreen design practice for the transfer of screened solids from the screen to the backwash system and out of the microscreen unit. A computer model of the process was developed in a format compatible with the EPA Executive Program for Optimization of Treatment Systems. |
