Real-life situations of Mineral wool.

a saline water is fed to a reverse osmosis unit at flow rate o rotameter connected to reject (retentate) line reads 8 installed in reject and permeate line reads 15.2 milli siemens/cm and 300 micro siemens/com respectively.

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
