| Abstract |
The objective of the study was to develop a microscreen model as a computer subroutine compatible with the executive program of the Federal Water Quality Administration. The goal for model development was that the model should enable one to predict microscreen performance when the process is used for treatment of secondary effluents as well as capital, operating, and maintenance costs associated with use of the process. A critical review of the solids removal mechanisms potentially operative in the microscreen process has been presented. The mechanisms examined include: mechanical screening; gravity settling; interception; impaction; Browian diffusion; molecular forces; electrostatic and electrokinetic forces; and chemical forces. The two primary design considerations have been the hydraulics and solids removal efficiency. Performance of specific microscreen installations have been tracked variously by : liquid balances; solids balances; screen and solids character; and screen loading rates. (Author) |
