Abstract

In this investigation, a mathematical model is built and solved with
computer programs to get results for the design calculations of the reverse osmosis
mode used to remove salt from the river water before being utilized in the boilers
of electrical power stations in Iraq. The principles of the reverse osmosis mode ,
the conditions and factors affecting their operation, are discussed .The number of
stages with their arraements in the reverse osmosis mode are calculated using the
cascades theory for the first time.
A mathematical model and computer programs including all the mentioned cases
are built and applied on the reverse osmosis mode of AL-Nassiriya and AL-Daura
electrical power stations. The results of these calculations are compared with the
practical results and showed a good agreement .
