As a mechanical engineer, you have been asked to design an RO desalination unit for a small the feed. The chemical composition of the feed is shown in Table $1.$ You may use Winflows software $($or any other suitable software$).$

Show all the steps of the design process including your assumptions $($Recovery$,$ type and number of elements per PV$,$ number of stages, etc.$)$ and results analysis.

What is the maximum recovery that can be achieved with one stage system?

What is the maximum recovery that can be achieved with two stages system?

You should submit a report including a soft copv of the design part using the software as well as your elaboration and discussion of the results.

Note: Do it as a group work and submit one report per group $($same members of the project group$).$
