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...
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...
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...
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....
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...
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...
Gazing behavior is a vital part of nonverbal communication, as it can provide information about attentional state, subtext, environment, and point of view. Both dogs and cats have previously been shown to display gazing behavior when presented with an unsolvable task, as well as follow nonverbal directional ques given by...
Reclaimed water is a key source in overall global water management and sustainability;
however, small concentrations of antibiotics in treated wastewater effluent threaten
induction of antibiotic resistance in naturally-occurring soil bacteria and pathogens in
irrigated soils. This type of chronic exposure has the potential to lead to more severe food...
Anammox (Anaerobic Ammonium Oxidation) is a significant biogeochemical process carried out by certain bacteria, generally referred to as anammox bacteria. These bacteria have the ability to anaerobically oxidize ammonium (NH4+) with nitrite (NO2-) to form nitrogen gas (N2) without an organic carbon source. While anammox bacteria are found in a...
