    Abstract: This disclosure describes systems, methods, and apparatus for counter-current solids leaching. A multi-stage countercurrent leaching chamber can include a top and bottom end, a barren liquor input, two or more regions for countercurrent mixing, and a barren solids output. The input can be configured to receive barren liquor. The two or more regions for countercurrent mixing and separation can be configured to mix and separate liquid and solid phases. The barren solids output can be configured to collect and discharge barren solids from the bottom end of the multi-stage countercurrent leaching chamber. A fluidized bed chamber and clarifier chamber can also be included, where the fluidized bed receives a fluidizable slurry of pregnant solids and the clarifier chamber aids in separating liquids from solids passing from a top of the fluidized bed chamber to the top end of the multi-stage countercurrent leaching chamber.

    Abstract: Treatment of silica-laden wastewater is herein described. Unlike traditional fixed bed designs that cannot use an activated alumina sorbent due to the high volumes of sorbent needed in a fixed bed design, the herein disclosed continuous cycle enables smaller volumes of sorbent to be used and thereby enabling activated alumina to be used. Adsorption, regeneration, and rinse regions are provided. Activated alumina is provided to the adsorption region along with silica-containing wastewater. A pH below the zero point charge for alumina is set, and this causes the silica to load onto the alumina. Gravity brings the loaded alumina to the regeneration region, having a pH equal to or greater than the zero point charge of alumina such that the silica is released from the alumina. The silica and alumina are further separated in the rinse region, and the regenerated alumina can then be returned to the adsorption region.

    Abstract: Methods and apparatus for removing contaminants from liquid using a continuously circulating stream of purifying media are disclosed. In one embodiment the method includes mixing a regenerated purifying media with a contaminated liquid containing diverse contaminants; co-currently transporting the purifying media and the contaminated liquid in a mixed state; removing, using the purifying media, while co-currently transporting the purifying media and the contaminated liquid, contaminants from the contaminated liquid so as to produce a mixture of a decontaminated liquid and a contaminated purifying media; and separating contaminated purifying media from the decontaminated liquid. In addition, the contaminated purifying media is contacted in counter current fashion with a regenerant solution so as to produce a regenerated purifying media and the regenerated purifying media is returned to the mixing step, whereby the continuously circulating purifying media selectively removes contaminants from the liquid.
