Imibuzo Evame Ukubuzwa (FAQ) Mayelana Nezinhlelo ze-RO Ezinosawoti Ophezulu
Yiluphi ukugxila kukasawoti okungasingathwa izinhlelo ze-RO ezinokugxila okuphezulu?
Standard brackish-water reverse osmosis elements are typically limited to feedwater below about 5,000 mg/L total dissolved solids, while seawater-grade elements routinely handle 35,000 mg/L and higher. With high-pressure construction, interstage boosting, and suitable energy recovery, specially designed high-salt RO systems can treat feeds above 70,000 mg/L in concentration duty. The practical limit depends less on the membrane itself than on the pressure rating of the vessels, piping, pumps, and seals. Above roughly 80 bar, designers often shift toward a hybrid approach that combines reverse osmosis with thermal or membrane distillation concentration. A pilot test on your actual water is the only reliable way to confirm achievable recovery and flux at extreme salinity.
