Jibei SWRO Desalination Plant
Converting Sea Water into High Quality Drinking Water
Overview: Nedtex was awarded a contract by the Taiwanese State Water Corporation (TWC) for the construction and operation of the Jibei Island SWRO desalination plant. Located west of the Taiwanese mainland, the island experiences high population density during tourist season but is nearly deserted during the off-season. Due to highly saline existing groundwater wells, TWC initiated a project to produce 600 m³/day of desalinated water. One of the challenges encountered was the requirement for a creative, out-of-the-box design due to logistical limitations stemming from the island’s small-sized port
BlueGen Water Solution: BlueGen Water implemented a unique solution utilizing a partial double pass RO process. This approach involves directing a portion of the initial pass permeate into the second RO system, while the remaining low salinity permeate bypasses the RO, undergoes re-mineralization, and mixes with the permeate from the second pass. This method increases mineral levels while significantly reducing energy consumption caused by high pressure, thereby reducing the plant’s environmental footprint.
In 2009, Ashdod Oil Refinery embarked on a project to construct a second power plant, CO-GEN 2, equipped with a dual-fuel fired 60MW Gas Turbine Generator and an Energy Recovery Heat Exchanger. A critical component of this initiative was the establishment of a new deionized water plant to serve the turbine’s water injection system and meet the refinery’s internal needs. The plant aimed at producing treated and demineralized water, vital for boosting power generation efficiency and reducing NOx emissions.
