A carbon nanotube-infused filtration membrane for higher throughput filtration of oil-containing wastewater. The structure of the membrane reduces fouling and increases mechanical strength thereby increasing filter lifespan and and enabling cheaper wastewater filtration. The membrane has application in industries needing to manage the disposal of oil-water emulsions such as oil fields metallurgical pharmaceuticals and petrochemicals.
The structure of the membrane reduces fouling and increases mechanical strength thereby increasing filter lifespan and and enabling cheaper wastewater filtration. The membrane has application in industries needing to manage the disposal of oil-water emulsions such as oil fields metallurgical pharmaceuticals and petrochemicals.; Large amounts of oil-water emulsions are used or produced in various industries such as in metal treatment and cleaning operations petrochemical plants and crude oil storage and transport. These emulsions need to be treated before being sent to municipal water treatment works which is often a costly process. Membrane filtration is widely used to separate oil from water due to the high quality of water produced low chemicals used and low energy consumption; but existing methods are affected by fouling of the filter through build of up organic and inorganic deposits on the membrane as well as concentration polarisation. Researchers have developed and tested a carbon nanotube (CNT)...
