    Abstract: A process and associated system for the improved reclamation of disturbed lands (e.g., mined lands) is disclosed. In particular, the system including a dewatering cyclone, a screw classifier, and a dewatering apparatus (e.g. a dewatering belt) arranged in series to enable rapid and cost effective dewatering of slurries containing dilute clay and sand tailings to create an improved engineered reclamation material (ERM). The ERM formed by the controlled combining of dewatered sand tailings with dilute clay slurry and with a flocculant and overburden. The ratio of clay:sand:overburden of the ERM may be achieved by balancing the solid content (Cw) and water content (1-Cw) materials of the clay slurry, sand tailings and overburden. In some embodiments, the system may include at least one additional component, such as, for example, static screen(s), centrifuge(s), vibrating screens, drum screens, belt screens, belt filters, and/or other liquid-solid separation devices.

    Abstract: The present invention relates generally to processes for converting fructose-containing feedstocks to a product comprising 5-(hydroxymethyl)furfural (HMF) and water in the presence of water, solvent and an acid catalyst. In some embodiments, the conversion of fructose to HMF is controlled at a partial conversion endpoint characterized by a yield of HMF from fructose that does not exceed about 80 mol %. In these and other embodiments, the processes provide separation techniques for separating and recovering the product, unconverted fructose, solvent and acid catalyst to enable the effective recovery and reutilization of reaction components.

    Abstract: A water treatment system is provided having an encapsulate manifold with a reverse osmosis cartridge and one or more filter cartridges, and an annular collar to adapt and connect the manifold to the cartridges. The filter cartridge includes a detent for being received within a slot in the manifold head for secure locking engagement. The water treatment system is also provided in a modular arrangement wherein manifold heads are physically and fluidly coupled together via a clip which interfaces with the modular manifold heads. The water treatment system also allows for a retrofit application to include a permeate pump. The cartridges are also designed to provide a minimum annular inlet gap to minimize spillage during changing of the cartridges.
