1. San Diego California, November 15-17, 2010 2nd annual Maritime Business & Technology Summit. Site specific studies for evaluating potential locations for desalinization plants Rogelio Vázquez González. Department of Applied Geophysics, CICESE, rvazquez@cicese.mx rvazquez@cicese.mx Panel 5: Desalination, Filtration and Purity Detection

2. The southwest of USA and northwest of Mexico are one of the fastest growing regions. We are faced with the challenge of expanding the basic service infrastructure to fulfill the growing demand, particularly fresh water. Introduction

3. South of the border the sources for the water being supplied to satisfy the current demand, are being operated at the limit of their capacity and locally there is no other groundwater sources.

4. Given that, the State Water Commission has considered desalinating sea water to satisfy their requirements. desalinating sea water to satisfy their requirements. Membrane processes – Reverse Osmosis – Nanofiltration – Electro-Dialysis Reversal – Forward Osmosis Thermal processes – Flash Distillation – Multi-Effect Distillation – Membrane Distillation Which method of desalination is most appropriate? Where ? Reverse osmosis (RO) is the most popular desalination process used in the world. Improvements in efficiency have led to reduce energy consumption, cheaper processing costs.

5. In October 2009, the State Water Commission of Baja California, established a General Agreement for Collaboration with the Center for Scientific Investigation and Higher Education of Ensenada (CICESE) to characterize the site to place a desalting plant and perform the environmental impact assessment. CICESE is a Public Research institution coordinated by the National Council for Science and Technology (CONACYT ).
