Incompatibility between Fenton’s Reagents and a potassium dichromate COD test provides interference that prevent accurate measurements of the concentration of organics from oxidized samples. Several treatment options were tested to remove this interference. Oxidation of reagents was eliminated as a potential method for removal of interference due to sample contamination....
Acid whey is the largest byproduct of the dairy industry but to date has few useful applications and is frequently discarded as a result. However, acid whey has a high carbon content, making it a suitable co-substrate for anaerobic co-digestion with raw sewage sludge. The synergistic effect of co-digestion has...
Stormwater picks up pollutants as it flows over impervious surfaces before ending up in water resources. Best management practices are implemented to remove pollutants from stormwater. Puralytics manufactures a stormwater treatment product called the LilyPad. The LilyPad consists of a titanium dioxide nanoparticle photocatalyst immobilized on polypropylene substrate. Treatment of...
The OSU-Benton County Green Stormwater Infrastructure Research (OGSIR) Facility was created to test various methods of stormwater treatment. At this facility, runoff from the Benton County Development Department property is captured and pumped into a bioswale. This bioswale is comprised of layers of rock, gravel, sand, and soil, and is...
Anaerobic co-digestion of fats, oils, and grease (FOG) for increased methane (CH4)
production has been of increasing interest to municipal wastewater treatment plants
(WWTP) due to the potential economic benefit of using the produced biogas for
cogeneration of energy. FOG loading increase must be done carefully to mitigate the
risk...
Urban stormwater runoff contains pollutants that have a detrimental effect on pond water quality and watershed water quality. Stormwater best management practices (BMPs), such as a constructed wetland, can treat these pollutants through processes like infiltration, adsorption, and plant uptake. It is hypothesized that the surface-runoff fed pond at Bruce...
Mangroves provide numerous ecosystem services, including biodiversity values such as nesting sites for piscivorous waterbirds. High concentrations of pisicivoirous birds are hypothesized to affect ecosystem dynamics, yet few studies have examined their effects in mangroves. We examined the effects of nutrient enrichment by colonial waterbirds at a mangrove rookery in...
