100074: Dual Affinity Membrane Hydrocyclone for Simultaneous Water Purification and Oil Recovery from Produced Water

A large amount of contaminated waste water is generated from wellheads at offshore platforms during oil and gas productions. These heavily oil-contaminated waters cannot be discharged directly back into the environment and are currently purified by a number of expensive separation techniques. Effective separation of waste water into water and oil...

Subsurface Water Retention for Sandy Soils

IntroductionCompetition for limited water supplies necessary for the production of crops on sandy soils is becoming more intense in the US and globally, particularly with the increasing need for biomass produced as renewable energy sources. Subsurface water retention technologies (SWRT) are designed to increase water use efficiencies by as much as 20...

090132: Synthesize Highly Reactive Subnano-Sized Zero-Valent Iron using Smectite Clay Templates

Zero-valent iron is a reactive and powerful reducing agent capable of breaking down toxic compounds. More recently, nanoscale ZVI has emerged as a remediation technology used to degrade toxic chemicals. The nanoscale material (10-100 nanometer particle size) is often preferred because it has significantly more surface area than standard ZVI, which...

090010: Single Nucleotide Polymorphism (SNP) Genotyping of E. Coli 0157:H7

E. coli O157:H7 is a major health problem causing infection in more than 70,000 patients a year in the United States. These infections may be both in large outbreaks as well as isolated sporadic infections in small numbers of individuals. The Center for Disease Control (CDC) typically uses Pulse Field Gel Electrophoresis (PFGE) for identifying...

080035: A novel fermentation process for intracellular lipase production using pelletized Rhizopus oryzae

Of known enzymes, lipases have attracted the most scientific attention due to their importance in industrial enzyme applications. In addition to their natural function of hydrolyzing carboxylic ester bonds, lipases can catalyze esterification, interesterification, and transesterification reactions in nonaqueous media. This versatility makes lipases...

060096: High Yield Glycerol to Propylene Glycol Conversion Process

The increased production of biodiesel has resulted in a concomitant increased availability of glycerol, a byproduct of the production process. As a result the price of glycerol has experienced a sharp downward spiral. Challenges have confronted biodiesel producers who have pursued Glycerol conversion to the Propylene Glycol, a more desirable and...

050077: Plant Extracts from Verbascum Species with Antifeed Propertyies for Arthopods

Many plant species produce noxious chemicals to kill or otherwise inhibit insect feeding activity. Many of these secondary metabolites are very potent and often very specific. Extracts from these plants can be used as environmentally safe bio-pesticides for crops or other plants such as flowers to inhibit insect damage, often as part of an integrated...

040138: Ceramic Membrane Filtration of Ozonated Water

Membrane filtration is considered one of the best available technologies for meeting Stage 2 D/DBP requirements. However, one of the major problems with membrane processes is the decrease in permeate water flux resulting from membrane fouling. In addition, although membrane filtration of drinking water provides a barrier against pathogens and particles,...
