Simpec - Reverse Osmosis Plants

Reverse osmosis plants take advantage of the physical permeability principle of a membrane to obtain water demineralization. This process is not merely a physical obstacle (determined by the size of the pores of the membrane) to the passage of the molecules, but exploits the different chemical affinity of the species with the membrane, enabling the passage of hydrophilic (or water-like) molecules chemically similar to water. From the point of view of the plant, the method uses the principle of tangential filtration, as well as other membrane separating techniques such as microfiltration, ultrafiltration, nanofiltration and MBR Membrane Bioreactor (see membrane technologies). For ultrapure water production using reverse osmosis plants, Simpec uses double-step reverse osmosis systems combined with continuous electrodeionization units (CEDIs). The continuous electrodeposition CEDI systems combine the use of ion exchange resins with their continuous regeneration by the electric current.
