ABSTRACT:
Organic pollutant spills on aquatic bodies may be collected by a method comprising distributing a plurality of buoyant magnetically susceptible, oleophillic, hydrophobic, resilient sorbent particles on the surface of the pollutant, allowing the sorbent to attract and bind the pollutant, magnetically collecting the pollutant-bound sorbent particles, compressing the pollutant-bound sorbent particles to expel the pollutant to a pollutant sump, allowing the compressed sorbent particles to recover from compression, and redistributing the sorbent particles on the surface of the remaining pollutant. An apparatus for the practice of the pollutant collecting method may be fabricated as a surface going aquatic vessel comprising a buoyant, pollutant storage tank, a rotatable cylindrical drum mounted on the tank normal to the relative flow of the aquatic body, a plurality of magnetic bands mounted circularly about the drum in parallel spaced relation, means for rotating the drum, means for wiping the drum, means for compressing, a sorbent storage and distribution hopper, means for conveying communicating from said means for wiping through said means for compressing to said sorbent storage and distribution hopper, a pollutant sump beneath said means for compressing, pollutant conduit means communicating between said pollutant storage tank and said pollutant sump, and means for propelling said vehicle through said aquatic body. An alternative collection and recovery apparatus may comprise a magnetic rake having an elongated handle, a support cross-member mounted normal to the handle at the point intermediate the handle length and adjacent a first end of the handle, a plurality of elongated magnetic tynes mounted along the cross-member in parallel spaced relation and extending parallel to the handle, a reciprocating pressing member having a plurality of tyne-accepting holes therein spaced along the length thereof and adapted to reciprocatingly mount to said tynes and parallel to said support cross-member and to be reciprocable from a first position adjacent the cross-member to a second position remote to said cross-member, and means for reciprocating mounted to said handle and connected to said pressing member. A sorbent particle suitable for use in conjunction with the method and apparatus for pollutant spill control may be fabricated from a buoyant, resilient, oleophilic, hydrophobic, synthetic plastic substrate and a plurality of non-abrasive magnetically susceptible particles imbedded in, and substantially evenly distributed throughout, said substrate.
