Abstract
A dishwashing method in which water having an oxidizing and disinfecting action is provided in a dishwasher and used as dishwashing water or added to a dishwashing water, wherein, to provide the water, a) a stream of untreated water is fed into a reverse osmosis device and separated into a concentrate stream and a permeate stream, b) ozone is produced by an ozone generator, and c) the ozone is introduced into the permeate stream emerging from the reverse osmosis device, wherein the reverse osmosis controls ozone production in that the ozone generator is configured such that ozone is only produced and mixed with the permeate stream when the reverse osmosis device is in operation.
Claims7
A dishwasher comprising a device that provides water having an oxidizing and disinfecting action, comprising:
- a) a reverse osmosis device in which a stream of untreated water is separated into a concentrate stream and a permeate stream,
- b) a line for the permeate stream, and
- c) an ozone generator for production of ozone,
- wherein the ozone generator is arranged within the line or coupled to the line such that, when the ozone generator is in operation, the ozone can be introduced into the permeate stream, and the ozone from the ozone generator is introduced into the permeate stream, either by an injector driven by the flow of the permeate stream or by a pumping device.
