Growth Patterns Of Bacteria In Pressurized Sewage, Dennis Mazzei
Theses
Primary sewage was pressurized at 100 psi for one hour. The effects of this pressure on the growth patterns of general and nitrifying bacteria were examined daily for eighteen consecutive days using Standard Plate Counts and Most Probable Number (MPN) estimates. In conjunction with these tests, the degree of biodegradability was also determined by measuring both daily biochemical oxygen demands (BOD's) and dissolved oxygen levels.
Graphical analysis of experimental data compare the BOD's exterted [sic] by microorganisms to their respective numbers of colonies as determined by plate counts of both pressurized and non-pressurized sanitary sewage diluted to 3. 00%. The …
