2.Summary

The reverse osmosis technology is utilized to produce the drinkable water. Process for making drinkable water can be divided into 3 processes, which are pretreatment, membrane process and post treatment. The pretreatment process should be applied differently depending on the feed water. The types of feed water are seawater and brackish water. Seawater has higher salt concertation, so that it needs more energy and high salt rejection membrane to make fresh water when compare with brackish water.

Much of the reverse osmosis process has already been highly technologically advanced. However, there are still some technological challenges. The current reverse osmosis membrane is vulnerable to contamination. Thus, we should develop high membrane fouling resistance membrane.

 

3. Application to research

This paper covers whole process of reverse osmosis process. Therefore, this paper is very helpful in learning the basics of reverse osmosis process.
