Reducing Decomposition Time In Landfills By An Aerobic Process, Cameron Clark
Reducing Decomposition Time In Landfills By An Aerobic Process, Cameron Clark
Paper Engineering Senior Theses
This experiment was performed to determine if sludge produced by the paper industry could be composted faster by promoting the aerobic degradation process. To perform this experiment, I chose a sludge produced by a virgin pulp mill. Once I collected sludge, it was dewatered to a moisture content of sixty-five percent or less. As soon as the sludge was dewatered, I set up four separate composting systems, three of which were run under aerobic conditions and one that was run under anaerobic conditions. The anaerobic conditions only had sludge and plastic for its bulking agent. In the aerobic systems there …

The Effect Of Hot Storage On High Yield Pulp, Jeffrey D. Hampton
Paper Engineering Senior Theses
In order to comply with new environmental regulations, the Menasha Corporation's Paperboard Division installed a 150 ton capacity blow tank and non-condensable gas collection system at the Otsego, MI mill. Concerns over the potential changes in pulp quality resulting from the hot storage time created a need for this study.
The objectives of the study were to determine the effects of hot storage under alkaline conditions on the refinability, fiber characteristics, and brightness of a semichemical mixed hardwood pulp. An experiment was designed to duplicate in the laboratory the internal conditions of the blow tank. Pulp was then stored at …
Analysis Of Crepe Blade Vibration, Mark J. Peterson
Analysis Of Crepe Blade Vibration, Mark J. Peterson
Paper Engineering Senior Theses
The goal of this project was to take the first step in analyzing this vibration. This meant setting up measuring equipment and analyzing basic blade vibrations.
In this experiment, a laboratory coater (Dow coater at Western Michigan University) was used instead of a tissue machine because it was readily available and easy to control and modify. An accelerometer was used to measure the vibration of a blade on the coater. A computer using Labview was used for data acquisition. Trials at various speeds were run with a piece of tape on the coater roll to cause and distinguish vibration at …
