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.
