Abstract

A water treatment system is provided, comprising a raw water tank (10) connected to a water supply (15), a reverse osmosis unit (20) arranged to produce purified water from water input from the raw water tank (10) via a raw water supply line (25), at least one water treatment facility (60) alongside said raw water supply line (25) downstream said raw water tank (10) and upstream said reverse osmosis unit (20), and a reuse water feedback line (35) arranged to feed waste water and / or grey water collected from said reverse osmosis unit (20) and / or said at least one water treatment facility (60) back to the raw water tank (10) for reuse. In a water treatment method in such a water treatment system, waste water and / or grey water collected from said reverse osmosis unit (20) and / or said at leastone water treatment facility (60) is fed back to the raw water tank (10) for reuse.

Description

technical field [0001] The present invention relates to water treatment systems including system parts or devices and methods for water reuse in water purification systems including reverse osmosis units, and in particular to reusing water from carbon backwash and / or in such devices and methods Or reverse osmosis discharge water. Background technique [0002] Reverse osmosis (RO) is a water purification technology that uses semi-permeable membranes to remove ions, molecules and large particles from, for example, tap water. In reverse osmosis, the applied pressure is used to overcome the osmotic pressure, ie the colligative property promoted by the chemical potential difference of the solvent, thermodynamic parameters. Reverse osmosis can remove many types of dissolved and suspended substances from water by retaining solutes on the pressurized side of the membrane and allowing pure solvent to pass through to the other side. A membrane is a selective membrane in which large ...
