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...

000032: Purification of Drinking Water Using Ozonation in a Fluidized Bed Bioreactor

The conventional approach to including ozonation in water treatment is to combine it with biological treatment (biotreatment). One problem of conventional ozonation/biodegration processes is that the biodegradable organic carbon (BDOC) in the organic materials formed by the initial ozonation is difficult to quickly remove during the subsequent biotreatment....
