Abstract
Abstract An oil-guide-boom which is effective in the removal of surface oil and residue from flowing water is disclosed. The boom includes two support members and a sheet extending between the supports in a trough-like manner. The sheet comprises a wire mesh material and a non-woven fabric. In operation the boom is placed in water toward the direction of flow so as to allow water to pass through the mesh portion of the sheet and to collect in the trough portion of the sheet. The boom has particular utility in that its structure and materials allow continuous removal of surface impurities from flowing water. Method of purifying water containing oil on the surface thereof utilizing the oil-guideboom is also disclosed.

Claim 4
Dependent Claim
194 words
Process for the removal of oil and residual matter from a running water surface employing a boom comprising, in combination: a. first and second longitudinal flexible buoyant members spaced apart in longitudinally opposed relationship; b. an oil collection barrier comprised of a non-woven fabric comprising oleophilic fibers, a first long edge of said fabric being connected to said second longitudinal flexible buoyant member in sealing relationship thereto; c. flexible connection means connecting a second oppositely disposed long edge of said non-woven fabric to said first longitudinal flexible buoyant member in spaced-apart relationship therefrom whereby liquid may flow under said first longitudinal member and over said second oppositely disposed long edge of said non-woven fabric and be collected between said secondlong edge and said long edge sealingly connected to said second longitudinal buoyant member, said process comprising passing the water containing oil and residual matter against said boom such that the oil first flows under said first longitudinal member and over said second oppositely disposed long edge of said non-woven fabric and said oil and residual matter is collected between said second long edge and said long edge sealingly connected to said longitudinal buoyant member.
