  • Method of treatment using a solid particulate material and apparatus therefor
    Patent number: 10773976
    Abstract: A method of treating a substrate with a solid particulate material and a treatment liquor comprising: agitating the substrate with said solid particulate material and said treatment liquor; and (a) separating the substrate from effluent comprising solid waste fragments derived from the substrate, said solid particulate material and the treatment liquor; (b) transferring said effluent to a hydrocyclone separator comprising an inlet, a first outlet and a second outlet, wherein the effluent is fed into the hydrocyclone separator via the inlet; (c) separating the effluent in the hydrocyclone separator to produce a first stream and a second stream, wherein the first stream comprises said solid particulate material and exits the hydrocyclone separator via the first outlet and wherein the second stream comprises treatment liquor and solid waste fragments and exits the hydrocyclone separator via the second outlet; and (d) collecting the first stream after it exits the hydrocyclone separator via the first outlet.
