Separation of Hydrocarbons from Water by Pressure Driven Membrane Processes

A Diffusion Membrane for Separation of Hydrocarbons from Water Streams

ABSlRACT Over the years a variety of technologies have been used to remove organic contamination from water. Unfortunately, most of these techniques are either too expensive or too complicated to operate and, in some cases, cause secondary pollution effects. Various membrane processes have been developed and tried but, unfortunately, little success has been realized. Membrane processes are gain...

Inorganic Fouling of Pressure-Driven Membrane Processes - A Critical Review

Separation of motor oils, oily wastes and hydrocarbons from contaminated water by sorption on chrome shavings.

In this paper, the ability of chrome shavings to remove motor oils, oily wastes and hydrocarbons from water has been studied. To determine amount of hydrocarbons sorbed on tanned wastes, a FT-NIR methodology was used and a multivariate calibration based on partial least squares (PLS) was employed for data treatment. The light density, porous tanned waste granules float on the surface of water a...

Magnetic Separation of Giardia Cysts from Water

Background: Giardia is one of the infectious agents that can be transmitted by surface water and cause a disease. We designed and fabricated a magnetic system to separate the giardia cysts from water. Materials and Methods: In this study, giardia cysts were concentrated by sucrose floatation method. The cysts were mixed with physiological saline and their concentration was adjusted to 100,000 c...

The Pursuits of Ultimate Membrane Technology including Low Pressure Seawater Reverse Osmosis Membrane developed by “Mega-ton Water System” Project

Reverse osmosis (RO) technology has been widely applied to water treatment such as seawater desalination, and large RO plants are many in operation around the world. Moreover, much larger plants will be required to secure sufcient water resource in the near future because global water shortage and quality problems are still getting more serious. Mega-ton Water System pr...
