  • Patent number: 6168710
    Abstract: Improved installation for cleaning/recovering liquids with particles in suspension, which is comprised of a first tank, which contaminated liquid with particles in suspension from cleaning the filtering equipment, reaches. This tank includes a guillotine-like mobile separation element, which subdivides it into two independent compartments. Contaminated liquid reaches one of them and the particles in suspension settle in the other compartment, forming sludge, which is evacuated to a second tank, which includes a grill-tank supplied with a renewable filter bag where the particles in suspension of this sludge are retained, recovering dirty liquid. This dirty liquid is evacuated to a third storage tank, from where it is recycled to the filtering equipment.

  • Patent number: 5013432
    Abstract: A filtering system for liquids with suspended particles is disclosed. The system consists of a receptacle for the liquid with suspended particles, a receptacle for the filtered liquid, a decanting receptacle for residual liquid, a filter, and a valve unit. The valve unit interconnects the receptacles through the filter in order for the filter to perform a filtering phase of filtering the liquid with suspended particles from the receptacle for liquid with suspended particles to the receptacle for filtered liquid; a filter-washing phase against the filter-flow from the receptacle for liquid with suspended particles to the decanting receptacle; and a rinsing phase from the receptacle for liquid with suspended particles to the decanting receptacle.
