Abstract:
A method for separating floating solid material from a fluid channel comprising:providing a helix boom further comprising a plurality of boom segments with the plurality of boom segments substantially along a common longitudinal axis, each boom segment including a central segment along the longitudinal axis and a fin segment attached to the central segment along a helical path and substantially perpendicular to the longitudinal axis, and an axle with a first end and a second end, said axle located substantially along the common longitudinal axis such that the helix boom freely rotates about the axle;anchoring the first end of the axle at a first side of the fluid channel;anchoring the second end of the axle at a second side of the fluid channel, such that the helix boom will float with approximately one half of the central structure submerged when liquid flows in the fluid channel and the fin is rotated by a flow of liquid in the fluid channel;whereby floating solid material will be conveyed to the first side of the fluid channel by the helix boom.
