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.
