Full Description

The state-of-the-art in large-scale seawater desalination is reverse osmosis (RO). Othertechnologies using thermal techniques, electrodialysis reversal, etc., still have significant drawbacks foruse with the raw water sources available in the Corpus Christi area and are only applicable in nicheapplications. For these reasons, RO was the sole desalination technology considered in this feasibilityanalysis.In terms of pretreatment, however, there are a variety of available technologies. Nonetheless, it is wellunderstood that the RO process requires a high quality feedwater to minimize fouling, maximizemembrane life, minimize pressure drop across the membranes, and to basically provide efficienttreatment. For these reasons, a robust, reliable, and effective pretreatment system is essential. Thus, themain focus of this paper is on the pretreatment alternatives, with specific objectives as follows:to briefly describe advantages and disadvantages of various pretreatment processes;to illustrate the methodology and rationale behind the initial pretreatment selection process andthe development of the short-list of most advantageous pretreatment processes; and,to present cost comparisons (capital, O
