Abstract: A system wherein an ultrasound emitter, or gun, is provided which emits an ultrasound beam directed at filter media, on the opposite side of the filter media from where solids accumulate, in order to knock the solids from the filter media. Dislodged solids from the area targeted by the beam are driven upstream, away from the filter media. Gravity then draws the solids to a drain of a collection chamber, which allows for the solids to be safely removed from the system. A guide is provided upstream of the filter media, the guide having angled slats or vanes. These vanes are angled upwardly towards the filter media and downwardly towards the drain, such that as the solids are blasted from the filter media by the gun, they are jolted upstream, and impact the angled vanes upon their downstream return.
