✦ Synopsis

Bechtel Group, Incorporated, undertook a comprehensive parametric technical and economic study of seawater reverse osmosis (RO) desalination plants. The objective was to derive updated costs for plants ranging from 100,000 gpd to 5 million gpd at a Caribbean site and at a continental U.S. site. The study considered: 0 hollow-fiber and spiral-wound membranes in one-and two-pass configurations 0 various seawater intakes (surface, seawater well, Ranney collectors) 0 various high pressure pumping systems (centrifugal, positive displacement) 0 optional energy recovery systems (Pelton wheel, hydroturbines, work-flow exchangers) 0 operation and maintenance (O&M) labor requirements Other v_ariables included: 0 reduced operating pressure 0 extended membrane life 0 higher recovery ratio 0 improved pumping and energy recovery 0 increased plant automation INTRODUCTION When this study was commissioned late in membrane elements, modules, and systems was * US Bureau of Reclamation c* Consultant system efficiency 1981, commercial acceptance of less than 13 years old.
