Abstract
Abstract
In the present work, a type of marine reverse osmosis desalination plant with 20t/d product operated at different condition (temperature, operation pressure, TDS) was studied. Within the different operation conditions, the TDS and flow rate of permeate change in relation to the operation pressure, temperature and TDS of seawater. The study shows that when the TDS of seawater is higher than 40000ppm or when the temperature of seawater is higher than 35°C, the TDS of permeate is higher than 500ppm and as such the permeate is not suitable for drinking. To satisfy the drinking water supply, two-level reverse osmosis or refrigerator for cooling the inlet water were suggested.
