This disclosure relates generally to phase separation, and more particularly, to a apparatus and a method for phase separation. In one example, the apparatus includes a spiral shaped body, split outlets and an adjustable splitter. The spiral shaped body includes an inlet portion to receive a mixture of phases associated with distinct effective masses, an outlet portion, and multiple helical turns stacked between the inlet and outlet portion. A portion of helical turns are twisted to form a twisted portion having opposite walls of a preceding helical turn turned relative to one another in opposite directions. The split outlets are configured at walls of the preceding helical turn to withdraw the phases based on an effective mass of said phases. The adjustable splitter is movably configured at least a portion of a cross section of the spiral shaped body to facilitate separate withdrawal of the one or more phases of the mixture.

A technique using a curved channel of a spiral device to introduce a centrifugal force upon neutrally buoyant particles flowing in a fluid, e.g. water, to facilitate improved separation of such particles from the fluid is provided. As these neutrally buoyant particles flow through the channel, a tubular pinch effect causes the particles to flow in a tubular band. The introduced centrifugal force perturbs the tubular band (e.g. forces the tubular band to flow in a manner offset from a center of the channel), resulting in an asymmetric inertial migration of the band toward the inner wall of the channel. This allows for focusing and compaction of suspended particulates into a narrow band for extraction. The separation principle contemplated herein implements a balance of the centrifugal and fluidic forces to achieve asymmetric inertial equilibrium near the inner sidewall.

A method of recycling a filler included in artificial turf by sorting the filler into two or more materials, including: a first sorting operation of sorting the two or more materials based on a grain size; and a second sorting operation of sorting the materials, which are sorted by the first sorting operation and have grain sizes belonging to a predetermined range, based on specific gravity.

Devices, systems, and methods for recovering metal constituents from a waste stream containing metals (e.g., incinerator ash) are described. The waste stream may include incinerator bottom ash, fly ash, or a combination thereof. A falling velocity separator is employed in combination with a centrifuge to separate and collect metals from the waste stream. The falling velocity separator uses a liquid to separate particles within incinerator ash according to the particles settling velocities. The centrifuge further separates particles from the incinerator ash according to density of the particles.

An apparatus for a spiral separator, for provision operatively intermediate upstream and downstream spiral trough parts of the spiral separator, including a slurry receiving region for receiving a mineral slurry flow from said upstream spiral trough part of the spiral separator; a splitter for splitting the mineral slurry flow into a concentrate part, a semi-concentrate part and a remainder part; a mixing region for mixing a more fluid radially more outward part of the remainder part with a less fluid radially more inward part of the remainder part, to provide a mixed remainder part for feeding onto the downstream spiral trough part; and a semi-concentrate bypass channel for conveying the semi-concentrate part towards the downstream spiral trough part, such that the semi-concentrate component bypasses and is segregated from the mixing region.
