  • Methods and systems for separating solid particulates from waste water
    Patent number: 10399881
    Abstract: A method for separating solid particulates from waste water includes receiving a first stream of waste water, and adjusting a specific gravity of the received waste water to within a pre-selected range. The method also includes channeling the adjusted waste water to a first hydro-cyclone system. The first hydro-cyclone system separates a first portion of solid particulates from the adjusted waste water. The method further includes transferring the first portion of solid particulates to a vibrating dewatering screen. The vibrating dewatering screen separates residual water from the first portion of solid particulates.
