“VINASSE TREATMENT PROCESS BY FLOTATION IN FLOW”, more precisely, it is a vinasse treatment process, by high performance flowing flotation system in industrial plants' facilities, resulting in obtaining concentrated vinasse sludge and treated vinasse, being said process comprised by vinasse treatment, which consists of treatment steps performed inside flotation tank, which comprises succession of coagulation systems and basins, flocculation, combined with aeration and oxygenation, in addition to a system of nano and micro bubbles in flotation basin, in which vinasse naturally flows into its storage tank, being said process results in formation of surface sludge and treated vinasse.

The subject invention provides safe, environmentally-friendly, compositions and methods for extracting minerals and/or metals from ore. More specifically, the subject invention provides for bioleaching using a composition comprising one or more biosurfactant-producing microorganisms and/or microbial growth by-products. In specific embodiments, the composition comprises biosurfactant-producing yeasts and/or their growth by-products.

An apparatus for harvesting algae from an open body of water includes a boat having a pair of spaced apart parallel flotation members and a deck disposed on and connected to the members. The spaced apart members define an area therebetween forming a process channel. A separating mechanism disposed on the boat separates the process channel into a plurality of process channel sections arranged in series. The process channel sections are disposed intermediate the flotation members. Each of the process channel sections include a deflector plate, a scum beach, a scum trough, and diffused air piping. The diffused air piping is in fluid communication with a dissolved air flotation system.

What is provided is a washing treatment system (1) for contaminated soil, including: a classifier (10) that is configured to obtain a sand fraction (S4) having a particle size within a predetermined range and a fine-grained fraction (S3) having a particle size smaller than the predetermined range, from contaminated soil (S0) containing one or more contaminants selected from dioxins and agricultural chemicals; a detaching/washing unit (20) that is configured to detach a contaminant particle containing the contaminant from a surface of the sand fraction (S4); a removal unit (30) that is configured to generate air bubbles in a presence of water containing a flotation chemical, allows the detached contaminant-bearing particles to attach to the air bubbles to form froth (F1), and removes the froth (F1) to obtain a first slurry (S6) containing primary purified soil; and an up-flow washing unit (40) that is provided downstream of the removal unit (30), and is configured to supply the first slurry (S6) into up-flow water (W2) to purify the primary purified soil.

A method of processing thin stillage in an ethanol refining operation is provided. In one embodiment, the method comprises treating stillage with an inverse emulsion comprising at least one anionic flocculant and an emulsifying agent selected from a sorbitan ester of a fatty acid, an ethoxylated sorbitan ester of a fatty acid, and combinations thereof, thereby forming treated stillage; clarifying the treated stillage via at least one of dissolved air flotation and induced air flotation, thereby forming clarified thin stillage and a float layer comprising oil and solids; separating the oil from the solids of the float layer; and recovering the oil.

An algae separation system can comprise a tank comprising an algae separation chamber. The system can comprise a first inlet to supply algae-containing water to a mixing region of the algae separation chamber. The system can comprise a second inlet to supply gas-containing water comprising dissolved gas to the mixing region of the algae separation chamber. The system can comprise a bubble generator in fluid communication with the second inlet, the bubble generator configured to generate a plurality of bubbles from the gas-containing water and to supply the plurality of bubbles to the mixing region to mix with the algae-containing water.

The invention relates to a method and an apparatus for separating lignocellulose particle fraction (3) and lignin particle fraction (4), in which crude lignin (1) formed from starting material (6) comprises lignocellulose particles and lignin particles. According to the invention, the method comprises adding stabilizing chemical (11) and/or hydrophobic chemical (12) into the crude lignin (1) in at least one step, and treating the crude lignin by separating the lignin particle fraction (4) and lignocellulose particle fraction (3) from each other in at least one separation step (2,8,9,10). Further, the invention relates to a lignocellulose particle fraction and a lignin particle fraction and their uses.
