  • Patent number: 7611624
    Abstract: A filtered grey water recycling system includes a waste water storage tank for receiving waste water from a stone processing system and a filtered grey water supply loop providing filtered grey water to the stone processing system. The filtered grey water loop includes a separation filter for removing large particulate waste from the grey water and a particle filter for filtering smaller particulate matter. The separation filter discharges the large particulate waste into the waste water storage tank and a clear water filter loop filters waste water from the waste water storage tank through a high pressure filter and discharges the resulting clear water into the waste water storage tank.
    Type: Grant

  • Patent number: 6896818
    Abstract: A water treatment and recycling system to provide grey water and crystal clear water to a stone processing system including crystal clear water stone fabrication equipment requiring crystal clear water and grey water stone fabrication equipment capable of using grey water. The system includes a waste water storage tank connected from the waste water discharge ports of the crystal clear water and grey water stone fabrication equipment, a grey water supply loop for pumping waste water from the waste water storage tank as grey water to the grey water stone fabrication equipment and a crystal clear water supply loop for pumping waste water through a high pressure filter to convert the waste water into the crystal clear water, and a crystal clear water supply pump for pumping crystal clear water to crystal clear water stone fabrication equipment. The high pressure filter includes a frame holding a filter stack.
