  • Publication number: 20130327361
    Abstract: The present invention is in the field of laundry processes and devices. In particular the invention relates to the saving of water. It is an object of the present invention to reduce the water consumption in conventional washing methods, especially machine washing methods. It is found that the continuous pH controlled sequential dosing of an electrolyte, followed by dosing of a polymer and a solid liquid separation step during a full wash cycle of a washing machine, provides continuous clarification of the wash liquor and enables the continuous reuse of the water during said wash cycle.
