Development of algal membrane bioreactor technology for wastewater treatment and polishing
(University of Missouri--Columbia, 2014)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The discharge of secondary wastewater effluent from wastewater treatment plants can lead to eutrophication of receiving water bodies due to the presence ... -
Dry weight and cell density of individual algal and cyanobacterial cells for algae research and development
(University of Missouri--Columbia, 2014)Phototrophs have received more and more attention due to their nutrient removal, biomass production as well as the potential for biofuel feedstock. This research determined the dry weight of algal and cyanobacterial cells ... -
The effects of alkalinity, hardness, and pH on the formation potential of disinfection by-products
(University of Missouri--Columbia, 2014)Chlorine is the most common disinfectant used; its use has dramatically decreased a number of waterborne diseases. However, the use of disinfectants creates another potential problem in the creation of disinfection by-products ... -
Emissions of greenhouse gases carbon dioxide and methane from duckweed systems for stormwater treatment
(University of Missouri--Columbia, 2014)This study determined the greenhouse gas emission from lab-scale duckweed treatment systems that were used for stormwater treatment. By using the static chamber technique, the fluxes of CO2 emission from the duplicate ... -
