Countercurrent systems and methods for treatment of contaminated fluids
First Claim
1. A system for treatment of contaminated fluid, the system comprising:
- a reservoir of an adsorbent nanomaterial designed to remove contaminants from contaminated fluid;
a reactor in fluid communication with the reservoir, and within which a fluidized bed of the adsorbent nanomaterial can be accommodated in the presence of a countercurrent flow of contaminated fluid for the treatment of contaminated fluid; and
a mechanism to maintain fluidity of the bed so that contaminated fluid introduced into the reactor can countercurrently flow through the bed.

Abstract
A countercurrent system for treatment of contaminated fluid is provided. The system, in an embodiment, includes a source from which contaminated fluid may be introduced into the system and a reservoir of an adsorbent nanomaterial designed to remove contaminants from contaminated fluid. The system also includes a reactor in fluid communication with the reservoir, and within which a fluidized bed of the adsorbent nanomaterial can be accommodated in the presence of a countercurrent flow of contaminated fluid for the treatment of contaminated fluid. The system further includes a mechanism to maintain fluidity of the bed so that contaminated fluid introduced into the reactor can countercurrently flow through the bed. A pathway can also be provided along which treated fluid may be directed away from the container, as well as a collector for removing spent adsorbent material from the system. A method for treating contaminated fluid is also provided.

23. A method for treating contaminated fluid, the method comprising:
-
providing a fluidized bed of an adsorbent nanomaterial within an environment where contaminated fluid can be treated;
introducing a flow of contaminated fluid into the environment, so that the fluid can flow countercurrently through the bed;
allowing the adsorbent nanomaterial in the fluidized bed to interact with the contaminated fluid as the fluid flow countercurrently through the bed, so that the adsorbent nanomaterial can attract and remove contaminants from the fluid; and
discharging treated fluid from the environment. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)
