Abstract
The present inventive concept relates to a method for recycling water in a water recycling device, the method comprising: receiving used water via a drain; determining a water quality measure of the used water; if the water; quality measure of the water is above a first quality threshold, feeding the used water to a valve arrangement; in the valve arrangement, forming water to be treated by providing external water, the used water or a combination of the external water and the used water; generating treated water by treating the water to be treated using a water treatment arrangement; and feeding the treated water to an outlet. The present inventive concept also relates to a water recycling device.
Claims14
A method for recycling water in a water recycling device, said method comprising:
- receiving used water via a drain;
- determining a water quality measure of said used water;
- if said water quality measure of said used water is above a first quality threshold, feeding said used water to a valve arrangement;
- in said valve arrangement, forming water to be treated by providing external water, said used water or a combination of said external water and said used water;
- generating treated water by treating said water to be treated using a water treatment arrangement;
- and
- feeding said treated water to an outlet.
A water recycling device comprising:
- an outlet configured to output treated water;
- a drain for collecting used water output from said outlet;
- a sensor configured for determining a water quality measure of the used water;
- a return path in liquid communication with said drain;
- a treatment path in liquid communication with said return path and said outlet;
- an external water path in liquid communication with said treatment path, said external water path being connected to an external water outlet;
- a valve arrangement configured to accept as inputs said used water from said return path and/or external water from said external water path, said valve arrangement being placed between said return path and said treatment path, said valve arrangement being configured to direct said inputs to said treatment path, said valve arrangement being configured to mix said external water with said water from said return path;
- a circulation pump for providing a flow in said water recycling device;
- and
- a water treatment arrangement placed downstream of said valve arrangement.
