Abstract

Laundry treatment appliances for use in a typical household include a tub that has an opening to provide access to the interior and at least partially defines a treating chamber into which fabric items such as clothes, towels, or linens can be placed to undergo a washing operation. A system can be provided for recirculating wash liquid through the tub to reduce water consumption. At least one tank or reservoir and a coagulant dosing system can be included for the chemical treatment of wash water as part of the wash liquid recirculation system. The tank can also serve to separate coagulated solids from the wash water.
