  • Apparatus and method for rejuvenation and recovery of filtration media
    Patent number: 11325058
    Abstract: Apparatuses and methods to rejuvenate spent filtration media are described. The apparatuses include a filtration unit to filter a liquid having solids that need to be removed and a rejuvenation unit to heat the spent filtration media that has reduced filtering capacity. The methods include using the apparatus to rejuvenate spent filtration media by removing solids deposited on the filtration media to allow its repeated reuse rather than being discarded and replaced with new filtration media.
