Hybrid EDR-Ro system
Reverse Osmosis, known as RO, is a process where water is demineralized by flowing under pressure through a semi-permeable membrane RO is widely used for desalinating water. High salinity disposal and low recovery efficiency of RO are real environmental and economical problems that should be considered.
Payamavaran Nanotechnology Fardangar Company introduces the hybrid system by using the EDR (Electro Dialysis Reversal) and Ro system, which EDR systems is supplied for recovery of effluents of RO units. The most important advantage of RO-EDR systems is decreasing the residual flow of desalination to approximately 5% of inlet flow. In this design residual flow of RO is recovered by EDR and returned into the input of the RO unit.
Advantages:
• Decreasing required chemicals of Ro unit
• Improving the performance and efficiency of desalination
• Reducing operating costs
• Decreasing the effluent of the desalination system
