"Different modifications and newer methods of treatment which utilize the basic trickling filter concepts, such as the Bio-Disc process, have been developed to increase the efficiency of wastewater treatment. The purpose of this investigation was to develop and evaluate a newer such method called the splash plate concept.
The splash-plate concept utilizes a series of circular plates mounted horizontally on a vertical axis. This allows the wastewater being treated to travel over one plate to the edge and splash down to the next lower plate and so on throughout the tower. A total of four units were operated at different organic loading conditions using domestic sewage and a mixture of milk and sewage. After a design period, there were two test periods for the evaluation of operation, with one period using artificial illumination. During these operating periods, pH, turbidity, chemical oxygen demand, solids determinations, nitrogen, and phosphorus measurements were taken as the means for evaluating the performance of the units.
It was found that the splash-plate process did not perform as favorably as other waste treatment processes with respect to removal of the various parameters evaluated. It was also found that problems existed with regard to channelization of the wastewater flow in the units. If channelization could be eliminated, then further consideration of the unit as a means of wastewater treatment should be investigated"--Abstract, page ii.
