Biodegradation of selected organic nitrogen compounds in activated sludge systems
(University of Missouri--Columbia, 2010)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Activated sludge systems are commonly used to remove organic matter and nutrients from wastewater. They are also used to remove synthetic organic ... -
Change in sludge settling and filtration properties and membrane fouling trends in MBR activated sludge systems operated at different solids and hydraulic retention times
(University of Missouri--Columbia, 2014)Membrane bioreactor (MBR) activated sludge process is increasingly used in wastewater treatment due to its excellence in solid-liquid separation and superior effluent quality, smaller bioreactor volume and foot print. ... -
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 ... -
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 ... -
Fabrication of TIO₂-embedded PVDF membranes and their application in algae membrane bioreactor systems
(University of Missouri--Columbia, 2013)Polyvinylidene difluoride (PVDF) membranes with and without TiO2 (5% by mass) were fabricated and applied for high-density algae cultivation in membrane algae bioreactors (MBR). Microalgae species Chlorella Vulgaris was ... -
Forward osmosis with an algal draw solution for wastewater concentrating and polishing
(University of Missouri--Columbia, 2018)Forward osmosis (FO) is an emerging wastewater treatment technology capable of high solute rejection by separating water from wastewater across a semi-permeable membrane. However, there is always leaking of ammonium from ... -
Hydrogen production from the dissolution of nano zero valent iron (NZVI) and its effect on anaerobic digestion
(University of Missouri--Columbia, 2014)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] -
Improved phosphorus removal in wastewater through combined bacterial and algal treatment
(University of Missouri--Columbia, 2012)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Increasingly strict nutrient regulations propel the need to develop more sustainable methods to remove nitrogen (N) and phosphorus (P) from wastewater. ... -
Kinetics of anaerobic digestion of selected C1 to C4 organic acids
(University of Missouri--Columbia, 2010)Anaerobic digestion involves multiple bacterial and archaea species to convert organic matter into volatile fatty acids and finally into methane and carbon dioxide. In this study, the effect of six selected C1 to C4 organic ... -
Metallic nanotoxicity to bacteria and bacteriophages
(University of Missouri--Columbia, 2010)The inhibitory effort of two commonly used nanoparticles, silver nanoparticles (Ag NPs) and zinc oxide nanoparticles (ZnO NPs), on the growth of bacteria (E. coli) and bacteriophage (MS2) were evaluated using a turbidimetric ... -
Rapid determination of algal growth kinetics using extant respirometry
(University of Missouri--Columbia, 2011)Algae have received increasing attention as a potential renewable source due to ease of biomass culture, fast growth rate, high biomass productivity, CO2 fixation and O2 production. For massive algal production algal kinetic ... -
Solids retention time-dependent phototrophic growth and microbial population dynamics in wastewater treatment
(University of Missouri--Columbia, 2013)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.]
