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...

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...
