Distribution Of Heavy Metals From Flue Gas In Algal Bioreactor, Katerine Napan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Algae are microscopic organisms with a great potential to produce biomass and lipids at productivities several times higher than terrestrial crops. To grow, these organisms consume carbon dioxide (CO₂), a greenhouse gas. This gas, emitted primarily by power plants after coal burning, can be effectively used for algae production, thus resulting in CO₂ remediation and biomass beneficial utilization as feedstuff, industrial filler and biodiesel feedstock. However, since coal is a fuel mined from the earth’s crust, it contains heavy metals that are released during coal burning and inevitably enter the algal cultivation system, contaminating the water were …

Phosphorus Distribution In The Bottom Sediments Of Hyrum Reservoir, Kirk L. Schmalz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The distribution of phosphorus in the sediment of Hyrum Reservoir was studied by collecting and analyzing 84 sediment samples for total, inorganic, organic, and water-soluble phosphorus.

Sample locations were mapped by triangulation and sediment phosphorus distribution maps were made. Sediment analysis showed average total phosphorus content of 755 micrograms per gram, with organic phosphorus composing approximately 97 percent of total phosphorus.

Sediment samples showed variability in phosphorus content which precluded identification of point sources of phosphorus input to the reservoir. Several areas of comparatively higher phosphorus content in the sediments were shown with isopleth maps.

An estimate of the extent …
