Nanobubble Generation & Uses
Activated sludge process is the biotic conversion of organic matter of wastewater to CO2 and biomass. The biological conversion of organic compounds in activated sludge relies on the efficient transfer of dissolved oxygen. Oxygen mass transfer from the gas phase to the liquid phase and microbial oxygen consumption are critical for effectively removing...

Microwave-Enabled Thermal Remediation of Organic Chemical Contaminated Soils using Dielectric Nanomaterials as Additives
Every year high volumes of hazardous organic pollutants, such as long-chain petroleum hydrocarbon, contaminate aquatic and soil ecosystems. This occurs because heavy compounds are less prone to natural weathering processes such as, volatilization, biodegradation, and dissolution. Furthermore, these pollutants harm the environment, animals, and humans...

Silver Salts and Impregnated Graphenes for Bromide Removal from Drinking Water
Silver Impregnated Graphene Oxide for Bromide Removal from Surface Water SI Case #M17-105P Background Bromide is widely present in natural waters, as well as in drinking water. Due to a wide variety of factors, bromide levels are increasing in both surface and ground waters. Because bromide itself is not known to pose any direct human or ecosystem...

Nano-Enabled Microwave Pretreatment of Wastewater Sludge to Enhance Subsequent Anaerobic Digestion
Nanomaterial and Microwave Augmented Biogas Production from Wastewater Residual Sludge Background The disposal of wastewater residual sludge costs an annual $2 Billion and is expected to increase over the coming years. Anaerobic digestion, the use of microbial metabolism to transform waste into usable or benign products, offers a potential solution....
