| Abstract |
In an attempt to study phosphorus uptake by biological slimes, a variable speed rotating disc apparatus was constructed. Correlations were attempted between mineral composition of the feed solutions and the phosphorus and nitrogen content of the resulting slimes grown on the discs. An inclined channel apparatus was also constructed and evaluated to differentiate physical or chemical mechanisms from biological mechanisms of phosphorus uptake. The angle of inclination was used to measure the kinetic rates before and after inactivation of the biological slime with ultraviolet light. With the disc apparatus, limited success of inducing biological uptake of phosphorus was obtained. Results from the inclined plane growth chamber showed that the limited phosphorus uptake that did occur could be related to metabolic activity rather than physical sorption or chemical precipitation. |
