High Rejection, Low Fouling Brackish Water RO Elements
The WK®-Series family of proprietary thin -film reverse osmosis membrane are characterized by high flux and high sodium chloride rejection.
WK®-Brackish Water Elements are selected when high rejection and operating pressures as low as 225 psi (1,550 kPa) are desired. These elements are recommended for challenging waters and wastewaters , brackish water with salt concentration (TDS) lev-els between 1,000 and 10,000mg/l or when very high salt rejection of mono- valent ions is required.
