A large-scale parallel-unit seawater reverse osmosis desalination plant contains many reverse osmosis (RO) units. If the operating conditions change, these RO units will not work at the optimal design points which are computed before the plant is built. The operational optimization problem (OOP) of the plant is to find out a scheduling of operation to minimize the total running cost when the ch...

In this paper, a waste heat liquid-liquid extraction method is considered for the seawater desalination. The mathematical model is a result of mass and energy balances, phase behaviour and salt distribution in the two phases. Because of the high non-linearity of the phase behaviour and the salt distribution these are being approximated by the use of piecewise linear approximations methods and t...

Nowadays freshwater needs were covered by fossil fuel-based desalination systems in many areas over the world. However, fuels’ excessive burning results rapid depletion and pollution of local environment as well threat to life sustainability. Therefore, through last few decades scientific community focused on relying solar energy seawater a clean alternative. Stepped stills, which convert requi...
