REVERSE OSMOSIS, WATER PURIFICATION OR DESALINISATION APPARATUS WITH ENERGY RECUPERATION AND PURIFIED WATER DOSAGE

摘要

A reverse osmosis purification apparatus comprises a hydraulic gear pump (2) that is driven by a driving motor (1) and generates a flow rate of salt water that is delivered to flow along at least an osmotic membrane (7) and then toward a hydraulic gear motor (3). The hydraulic pump (2) and the hydraulic motor (3) are coupled to each other by a shaft (12), and the displacement of the hydraulic pump (2) is greater than the displacement of the hydraulic motor (3).
