| Abstract: | The Polymetrics seawater reverse osmosis (RO) facility at Ghar Lapsi, Malta, is one of the largest seawater RO plants in the world, with an installed capacity of 20,000 m3 /d (5.3 U.S. mgd). A second plant, provided under the same contract, has a capacity of 4,500 m3 /d (1.2 U.S. mgd), utilizing highly brakish feedwater. The plants supply potable water for the island's 350,000 residents and its growing tourist trade.The seawater plant is a single pass design, utilizing DuPont permeators and is the first major installations incorporating energy recovery turbo-pumps.This paper summarizes the plant design, manufacture, assembly, and installation, and also reports up-to-date operation and maintenance data. The operating costs are presented. |
