The invention relates to a program-controlled apparatus () for washing items that is equipped with a water purification system () for purifying the wash liquor by removing detergent and suspended soil, which purification system () 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.

Washing machine comprising a water purification system

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. This filtration apparatus comprises: &#x22c5;a filtration chamber comprising an inlet opening that is located near the bottom of the filtration chamber, and an outlet opening that is located near the top of the filtration chamber; &#x22c5;a screen covering the outlet opening of the filtration chamber; &#x22c5;a first dosing unit that is located upstream of the filtration chamber adapted to release water-soluble components into the stream of aqueous liquid that flows from the inlet to the filtration chamber; &#x22c5;a particulate filter media that partially fills the interior of the filtration chamber; &#x22c5;a flow regulator that regulates the flow rate of aqueous liquid through the filtration chamber and that can operate in a high flow rate mode or a reduced flow rate mode; &#x22c5;a timer that controls the flow regulator; wherein the timer is programmed to alternatingly switch the flow regulator from the high flow rate mode to the reduced flow rate mode.
