A belt system for a water treatment system comprising a flocculation tank. The flocculation tank is configured for receiving wastewater having one or more of unwanted waste solids, unwanted particulates, suspended solids via the ingress and for mixing the wastewater with a flocculating agent and magnetite within the flocculation tank. The belt system comprises a looped belt comprising a plurality of rare earth magnets. The first looped belt is mounted within an extraction portion of the flocculation tank. A first portion of the first looped belt is above a water level inside the flocculation tank. A second portion of the first looped belt is submerged in the flocculation tank. A first scraper is positioned proximate to the first looped belt that is above the water level. A container is below the first scraper and the first looped belt and above the water level. An auger is within the container.

A method is provided for pre-treating biomasses, more particularly, for pre-treating biomasses intended for a biorefinery or similar facility for producing biofuels. The method comprises the steps of shredding the biomasses, removing foreign bodies contained in the biomasses upstream of the step of shredding, and soaking the biomasses by immersing the biomasses in water upstream or downstream of the shredding step. A plant for pre-treating biomasses is also provided. The plant comprises a shredding station for shredding biomasses, a station for removing foreign bodies from the biomasses upstream of the shredding station, and a soaking station for soaking the biomasses upstream or downstream of the shredding station.

Methods of reducing copper metal content of shredded scrap steel are provided. The method includes continuously separating a first scrap steel fraction from an amount of scrap steel concurrently with separating a second fraction from the amount of scrap steel; continuously separating the second fraction and providing a nonmagnetic fraction and, concurrently, a third scrap steel fraction; grinding the nonmagnetic fraction followed by magnetic separation to provide a fourth scrap steel fraction and, concurrently, an enriched nonmagnetic fraction; continuously combining the first scrap steel fraction, the third scrap steel fraction, and the fourth scrap steel fraction to obtain a combined scrap steel product comprising scrap steel with reduced copper metal content; and introducing the combined scrap steel product to an electric arc furnace. Systems of reducing copper metal content of shredded scrap steel are also provided.

A system and method directed to the economical recovery of valuable iron constituents from iron blast furnace and steel-making slag fines wherein the slag is obtained and subjected to a series of classification steps which progressively sort the slag fines by various physical characteristics, including magnetism, size, and density, into relatively iron-rich and relatively iron-poor classifications, resulting in the isolation of iron-rich commercial byproduct at one or more of the classification steps.
