Transcribed Image Text:
Potable water (total dissolved solids <250 ppm) can be obtained from seawater in a single stage design using high performance membranes. Calculate the required membrane area, number of modules and energy consumption of a 1000 m³/day single-stage seawater desalination plant. In order to recover part of the energy consumption a water turbine is included as part of the process. The data necessary for the calculation are as follows: Permeate flow rate Pressure difference Flux Rejection Salt concentration Recovery Pump efficiency 1000 m³/day 55 bar 1.3 m³/m²-day (measured at 15 bar pressure difference, T 16 °C and 1500 ppm NaCl) 99.5% 35,000 ppm NaCl 0.3 0.65 0.75 Membrane area per module 3 m² Turbine efficiency Potable water (total dissolved solids <250 ppm) can be obtained from seawater in a single stage design using high performance membranes.
