Reverse osmosis (RO) technologies have been widely implemented around the world to address the rising severity of freshwater scarcity. As desalination capacity increases, reducing the energy consumption of the RO process per permeate volume (i.e., specific energy consumption) is of particular importance.
Energy consumption is a key factor which influences the freshwater production cost in reverse osmosis (RO) process. Energy recovery and reuse options have already been very well explored in the current desalination industry.
Conclusion and Future Opportunities Efficiency of ~ 50% for the reverse osmosis unit operation (Fig. 2.12) with electrical energy as an input is quite good. Half of the energy consumption is accounted for by thermodynamics, which cuts any further improvements in half right at the outset.
Energy consumption and efficiency of high-pressure reverse osmosis was investigated. The choice of the water recovery in each stage is critical for optimum efficiency. The energy efficiency 2-stage RO and 3stage-RO were compared for ZLD. PRO can help reduce the energy consumption of high-pressure RO.
Membranes are packed into modules, which have frictional losses and losses due to concentration polarization on the membrane surface. For reverse osmosis, the source of energy comes from a pump and an energy recovery device is used to recover the pressure energy from the concentrate.
We also showed that operating with three RO stages can lead to better water recovery and less energy consumption with comparison to two-stage RO, if the recovery of each stage is correctly chosen.
