Emergency Water Treatment Methods Through The Adaptation Of Natural Disaster Building Debris, Benjamin Colston
Emergency Water Treatment Methods Through The Adaptation Of Natural Disaster Building Debris, Benjamin Colston
Williams Honors College, Honors Research Projects
The primary objective of this research was to determine whether concrete slag acquired from building debris in a disaster can be utilized to remove pathogens biochemically through changes in pH or physically through filtration. Direct Plate Enumeration testing was completed for different water samples to compare the general activity of bacterial growth as an indication of pathogenic potential. Throughout each experiment, the pH of different water samples was monitored and consistently indicated that water samples in contact with concrete pieces (concrete water samples) would exhibit a higher pH than samples with no exposure to concrete (control water samples). Compared to …

Harmful Algal Blooms (HABs) are a devastating ecological and economic consequence of the abundance of nutrient-rich agricultural runoff entering aquatic ecosystems (Baker et al. 2014). Bioavailable phosphorus from synthetic fertilizers is one of the major nutrients contributing to this global issue. Preliminary studies indicate that dissolved phosphorus can be removed from an aqueous environment when passed through a composite mixture of granular steel wool particles and activated carbon (Erickson, Gulliver, and Weiss (2007). Further research was conducted using higher quality concentration measurements to determine what grades of steel wool (0000, 000, 00) and types of activated carbon (GAC, PAC, EAC) …

Harmful Algal Blooms (HABs) are a devastating ecological and economic consequence of the abundance of nutrient-rich agricultural runoff entering aquatic ecosystems (Baker et al. 2014). Bio-available phosphorus from synthetic fertilizers is one of the major nutrients contributing to this global issue. Previous studies indicated that dissolved phosphorus can be removed from an aqueous environment when passed through a composite mixture of granular steel wool particles and activated carbon (Erickson, Gulliver, and Weiss, 2007). In this project, we conducted experiments using higher quality concentration measurements to determine what grades of steel wool (SW-0000, SW-000, SW-00) and types of activated carbon (granulated …
