Abstract
A new device, method, and system are disclosed that provide for removal of undesired materials from a contaminated fluid. Materials present in the fluids are kept in motion in one or more filter cassettes that include disc aerators that improve contact times with the sorbents and that rotate the filter media to pump contaminated water through the filter media for treatment of the contaminated fluids. The device and system provide containment of sorbent fines that keeps the filter media free from clogging.
Claims32
A fluid treatment system for removing a material from a contaminated fluid for treatment thereof, characterized by:
- at least one filter cassette defined by a pair of opposing discs of a preselected size disposed on a rotation member, each disc in said at least one pair is separated from the other disc a preselected distance;
- and
- a mesh filter of a preselected mesh size affixed to said discs that spans said preselected distance between said discs that defines a cavity of a preselected filter volume therein, said cavity includes a preselected quantity of a sorbent therein;
- whereby said rotation member provides rotation of said filter cassette at a preselected rotation rate through said fluid that mixes said sorbent with said contaminated fluid introduced thereto thereby removing said material from said fluid.
A method for treating a contaminated fluid in a treatment zone, comprising the steps of:
- mixing said contaminated fluid comprising at least one metal and/or at least one solid material with a preselected quantity of a metal-selective sorbent at a preselected rotation rate to provide continuous mixing of said sorbent with said contaminated fluid, wherein said sorbent binds with said at least one metal removing same from said fluid to a preselected release limit forming a treated fluid;
- and
- filtering said treated fluid of said at least one solid material to form a filtered treated fluid.
