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.

Dishwashing method and dishwasher

A connection head for a filter cartridge, which is easy and safe to handle. The connection head comprises a housing that has an inlet and an outlet, wherein said inlet and outlet have a port to which a detachable adapter piece for water conduit can be mounted. The adapter piece is attachable by a quick-release fastener. The quick-release fastener comprises a locking element, which locks the adapter piece by being rotated by about less than 90&#xb0;.

Connection head for a filter cartridge and filter cartridge

A cartridge for treating drinking water, the cartridge comprising a mixture of an ion-exchange material, one part of which is a highly acidic ion-exchange material and another part of which is a weakly acidic ion-exchange material, wherein one of the materials is loaded with alkali ions or alkaline earth ions.

Cartridge for the treatment of drinking water and method for purifying drinking water

A cartridge for treating drinking water, comprising two chambers, wherein one chamber is filled with a highly acidic ion-exchange material and another chamber is filled with a weakly acidic ion-exchange material, wherein one of the ion-exchange materials is loaded with alkali ions or alkaline earth ions.

Ion exchange cartridge for treating drinking water

A membrane separation device that treats water constructed such that at least two permeate streams of different electrical conductivity are generated therein, including at least two membrane modules arranged in a common pressure vessel such that they can be successively subjected to incoming flow of the water to be treated, wherein the pressure vessel is a tube in which the at least two membrane modules are arranged one behind the other in an axial direction and the at least two membrane modules are spirally wound modules.

Membrane separation devices and water treatment plants

A description is given of a multistage process for treating water, wherein a water stream is purified in a membrane separation stage and a downstream deionization unit having at least one concentrate chamber and at least one diluate chamber, wherein the water stream is separated in the membrane separation device into a concentrate stream and at least two permeate streams of different electrical conductivity, and wherein at least the permeate stream having the highest electrical conductivity is fed at least partially into the at least one concentrate chamber and at least the permeate stream having the lowest electrical conductivity is fed at least partially into the at least one diluate chamber of the downstream deionization unit. In addition, a membrane separation device is described which is constructed in such a manner that at least two permeate streams having different electrical conductivity can be generated therein, and also a water treatment plant, comprising at least one such membrane separation device and at least one deionization unit having at least one concentrate chamber and at least one diluate chamber.
