This investigation has led to the following conclusions:

1. Good removals of most bacterial species were observed.
2. Increased length of settling time increased the percent removal of pure cultures.
3. The solvent coagulation process worked best at a pH very near the pH produced by the bacteria during growth.
4. There was no advantage in changing from room temperature. S. proper surface active agents aided in the coagulation of bacteria in the solvent ooagulation process.
5. Almost all of the bacteria in suspension after the coagulation process were not viable.
6. Good removals were observed using the solvent coagulation process on mixed cultures.
7. The chlorinated solvent coagulation process shows promise for commercial operations.
