Abstract
The major goal of the presented study has been studying the reverse osmosis (RO) characteristics for (Ni, Fe, Pb, Ca, Cu, K, U, and Th) removal from aqueous solution. This was done by examining the impact related to temperature and pressure on the performance regarding the RO membrane in the removal of elements with time. Three temperatures (25,35 and 45 oC) and various pressures such as (2,4 and 6) bars were used in this work. It was found that, as the pressure increase, the flux permitted and rejection of elements are increased. The temperature increases the flux permitted while the rejection of elements was steady-state almost with the increase in temperature for all heavy and radioactive elements. It also shows that these a steady-state has stopped after 35 ºC and rejection start to decrease.
