Abstract: The application of reverse osmosis without any auxiliary technologies to the ultrapurification of technical grade hydrogen peroxide to obtain a quality enough for its use by the semiconductor industry is a great challenge. Through modeling based on membrane transport equations and mass balances, different integrated reverse osmosis cascades have been planned and simulated to produce the several electronic grades chemical. The sensitivity of different design and operation variables (recovery rate and applied pressure) on the system performance was also investigated. Finally, a non linear optimization approach to maximize economic profit while optimizing recovery rates and applied pressures was carried out.
