"' Eggshell and protein membrane separation "'is a recycling process.
2.
The natural gas is purified by a membrane separation process that removes water vapor and carbon dioxide.
3.
Other processes include membrane separation, cryogenic fractionation, and adsorption using molecular sieves ( Herzog ).
4.
In this capacity, he designed and implemented wastewater treatment plants using chemical, electrolytic or membrane separation processes.
5.
However, membrane separation is less attractive due to the relatively high capital and operating costs as well as other technical factors.
6.
At that point in time the division was known as the Ionics Consumer Water Products Group and was mainly involved in membrane separations technology.
7.
The membrane separation of the FO process in effect results in a " trade " between the solutes of the feed solution and the draw solution.
8.
Major step in this front is through the development of Industrial effluent recycle solution which integrates physiochemical, biological and membrane separation processes for optimum water recovery.
9.
In addition to these, the use of membrane separation technology for biogas upgrading is increasing, and there are already several plants operating in Europe and USA.
10.
In recent reviews covering membrane applications to bioreactors, it has been shown that, as with other membrane separation processes, membrane fouling is the most serious problem affecting system performance.
