Abstract:
1. A fluid treatment system for removing metals from a metal-contaminated fluid, said system comprising: a reactor with an inlet disposed at the bottom thereof for introduction of a contaminated fluid therein; a metal-selective sorbent within said reactor configured to disperse into said contaminated fluid as the contaminated fluid is introduced to said reactor, wherein the metal-selective sorbent removes metals from the contaminated fluid yielding a treated fluid, and the metal-laden sorbent settles via gravity to the bottom of said reactor; and a floating outlet that floats on the to of said contaminated fluid introduced to said reactor and delivers treated fluid through said floating outlet from said reactor; a filter tank having an external wall, a filter disposed in the filter tank and surrounding a first chamber and defining a second chamber between an exterior surface of the filter and an internal surface of said external wall, the filter tank including a first inlet connected to said floating outlet and opening into a to of the first chamber for directing treated fluid from the reactor outlet into the first chamber, the filter tank having a second inlet opening into a bottom of said first chamber for directing contaminated fluid into said first chamber, the filter chamber having a first outlet opening into a bottom of said second chamber for directing filtered fluid out of said second chamber, and the filter chamber including a second outlet connected to the reactor inlet and opening into the bottom of the first chamber for directing contaminated fluid out of the first chamber and into the inlet of the reactor.
