Efficient Hydrocyclone for Liquid-Liquid Separation
Executive SummaryDue to
environment
al concerns, discharge of water from oil and gas industries is required to maintain oil levels between 10 – 30 ppm. Complying with these standards leads to significant expenses for the industry. A new hydrocyclone design developed at MSU makes it possible to exceed these requirements while being much more co...

Real-Time 3D Modeling Of Watersheds
Executive SummaryGroundwater is the most extracted raw material in the world. As such, it is crucial that companies and governments are able to understand exactly how their use of groundwater affects the immediate area. Visualizing where groundwater is located, how chemical contaminants affect groundwater over time, and predicting how weather will ...

Method for the Removal of Fluoride From Water
Executive SummaryToxic levels of fluorine in drinking water arise from two different sources, naturally from the rock bed and artificially from commercial processing and waste. Fluoride removal processes are too costly and labor intensive for many developing countries. MSU researchers have discovered a new material that allows for efficient fluor...

Gliding Robotic Fish Navigation and Propulsion
Executive SummaryAutonomous robots provide a means to remotely perform a wide variety of tasks. For underwater robots an energetically passive mode of movement is important as well as a platform capable of a variety of sensors. We have developed a bio-inspired robotic vehicle based on the body of ray-finned fish. The robot has a reconfigurable sens...

Low Cost Hydrogenation of Bio-oils
IntroductionThere is a strong need for reliable and efficient energy alternatives to non-renewable petroleum. One renewable alternative for energy is bio-oil derived by biomass pyrolysis. However, bio-oil is impractical because it is corrosive to containment materials, self-reactive, and prone to polymerization, making it unfit for use within exist...

Multiscale Porous Polymer Films and Their Applications
IntroductionReverse osmosis (RO) is one of the most common technologies to purify water in locations where potable water is scarce. RO is the dominant production process for ocean water desalination and is also used in the production of bottled mineral water and boiler water purification in power plants. Thin-film composite membranes are the hear...
