Abstract: A tablet for forming a liquid dishwash composition on dissolution in water comprising from 0.1 to 40% wt. surfactant, an effervescent, an acid salt selected from sodium bisulphate, monosodium phosphate and mixture thereof, and a disintegrant.

Abstract: The invention relates to a program-controlled apparatus (1) for washing items that is equipped with a water purification system (8) for purifying the wash liquor by removing detergent and suspended soil, which purification system (8) utilizes addition of flocculant, wherein the amount of flocculant that is added is controlled to minimize the total amount of flocculant used without compromising the efficacy of the purification treatment.

Abstract: The invention relates to an apparatus for the filtration of aqueous liquid that is capable of effectively removing suspended particles from aqueous liquid during a prolonged period of time without clogging of the particulate filter media and associated pressure build-up.

Abstract: The present invention provides a detergent composition for use in a water-utilizing appliance, that allows for selection of an enhanced mode of operation of the appliance, based on the detection of a marker molecule in the solution of the detergent composition, where the enhanced mode comprises treatment of waste water generated during use of the appliance. The present invention also provides a method of selecting an enhanced mode of operation in a washing machine including a sensor assembly for detecting the presence of a marker molecule in a solution of the detergent composition.

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.
