摘要：

Taking three examples of plants with brine concentrators, we analyse energy consumption of existing and projected systems. This includes plants using Turbocharger boosting system, Turbocharger boosting with additional Impulse turbine and Impulse turbine acting as boosting and recovery system. Energy consumption of the high pressure systems and the high pressure pumps are compared. Sites analysed are Curacao and a 7,000m(3)/d and 15,000m(3)/d projected trains. Component optimisation is undertaken to achieve the lowest possible energy consumption of the SWRO plant. This investigation shows that an energy consumption of 2.58 kWh/m(3) product water is possible for the complete high pressure feed pump system.
