ACTIVE PRESSURE INTENSIFIER, REVERSE OSMOSIS SYSTEM AND USE THEREOF

摘要

The invention relates to an active pressure intensifier comprising an axial piston pump with a housing in which there is arranged a drum driven to rotate by means of a driveshaft and having at least two piston chambers, each of the piston chambers having a liquid inlet and a liquid outlet, and a piston with at least one piston rod being arranged in each of the piston chambers. The invention likewise provides a reverse osmosis system comprising this active pressure intensifier. The invention likewise provides a process for changing the concentration of dissolved constituents in liquid solutions by means of reverse osmosis. The subject of the invention finds use particularly in seawater and brackish water desalination, in wastewater treatment, in the food and drink industry, in the chemical industry and in mining.
