A water treatment apparatus using a lamella structure according to an embodiment of the present invention includes a first treatment tank which includes a plurality of inclined plates and is configured to pass water subject to treatment between the inclined plates adjacent to each other and a second treatment tank which is installed at a rear end of the first treatment tank to accommodate the water subject to treatment and into which bubbles are supplied, wherein the plurality of inclined plates include positive electrode plates and negative electrode plates that are alternately arranged, and the water subject to treatment passes between the positive electrode plate and the negative electrode plate.

A system for separating mineral particles of interest from an ore features mineral processing operations/stages/circuits configured to receive an ore, or mineral particles or concentrates formed by processing the ore, and provide processed mineral particles or concentrates, or a waste stream, for further enhanced mineral separation downstream processing; an enhanced mineral separation processor having a collection apparatus located therein, the collection apparatus having a collection surface configured with a functionalized polymer including molecules having a functional group configured to attract the mineral particles of interest to the collection surface, the enhanced mineral separation processor receive the processed mineral particles or concentrates, or the waste stream, and provide further enhanced downstream processed mineral particles or concentrates, or a further enhanced downstream processed waste stream; and a high intensity conditioning operation, stage or circuit configured to apply a high intensity form of energy to the processed mineral particles or concentrates, or the waste stream, prior to further enhanced mineral separation downstream processing by the enhanced mineral separation processor.

An electroflotation apparatus for removing impurities from waste water includes an electrolytic cell for treating the waste water and generating a flock containing the impurities and an outlet pipe having a linear central axis located co-axially with the electrolytic cell for passing the water and flock from the electrolytic cell to a separation area. The outlet pipe comprises a first end connected to the electrolytic cell and having a first diameter, and a second end through which the treated water and flock exit the outlet pipe, the second end having a second diameter. The outlet pipe reduces the turbulence of the treated water from the electrolytic cell before the treated water is passed to the separation area such that aggregation of the flock in the separation area is increased.

A method for recovering at least one precious metal from an aqueous solution containing the metal and particularly to recovery of silver and optionally one or more other precious metals from overflow of a sedimentation unit such as a thickener, a clarifier or a pond includes subjecting the aqueous solution to a micro and/or nanobubble flotation, wherein the pH of the aqueous solution is at most 1.5.

A method for purification of water with a water purifier. The water purifier includes an anode and a cathode as electrodes in such a way that a gap remains between the anode and the cathode. In the method, an electric field is generated between the anode and the cathode, water for purification is conveyed to the gap and an additive enhancing floc formation is introduced to water for purification or to purified water in an amount of less than 50 g and at least 1 g, measured as dry matter, per each cubic metre of water for purification. Floc material manufactured with the method, when water for purification is municipal wastewater. The use of the floc material produced in this way as a soil conditioner or for manufacturing a soil conditioner.

A method for recovering at least one precious metal from an aqueous solution containing the metal and particularly to recovery of silver and optionally one or more other precious metals from overflow of a sedimentation unit such as a thickener, a clarifier or a pond includes subjecting the aqueous solution to a micro and/or nanobubble flotation, wherein the pH of the aqueous solution is at most 1.5.

A process for the depression of iron sulphides and other disposable elements in the mineral concentration by flotation and electrochemical reactor. The proposed invention represents a method based on the action of electrodes on the mineral, which can replace, compliment or minimise the consumption of chemical reagents, as well as improving the effect thereof.

An electroflotation apparatus for removing impurities from waste water is disclosed. The apparatus comprises an electrolytic cell for treating the waste water and generating a flock containing the impurities as well as an outlet pipe having a linear central axis located co-axially with the electrolytic cell for passing the water and flock from the electrolytic cell to a separation area. The outlet pipe comprises a first end connected to the electrolytic cell and having a first diameter, as well as a second end through which the treated water and flock exit the outlet pipe, the second end having a second diameter. A length extends between the first diameter and the second diameter. The ratio of the second diameter to the first diameter is between 1.5:1 and 6:1. The ratio of the length to the first diameter is between 7:1 and 45:1. The outlet pipe reduces the turbulence of the treated water from the electrolytic cell before the treated water is passed to the separation area such that aggregation of the flock in the separation area is increased.

The present invention relates to delivering sample preparation technologies to enhance the performance of point-of-care agricultural diagnostics by improving the capacity to detect trace contaminations of pathogenic organisms along the entire food supply chain including pre- and post-harvest processing and distribution. Sample preparation is crucial for adequate test performance of downstream diagnostics like LAMP and supports sensitive detection of bacterial contaminates. This invention increases the speed and scale of routine pathogen surveillance and the efficacy of management response and mitigation of foodborne disease outbreaks.

The embodiments of this disclosure are related to a water treatment system comprising a flotation tank, a shell-tube inlet conduit connected to the flotation tank and comprising a shell configured to supply a gas and at least one tube configured to supply untreated water, wherein each of the shell and the tube has a first part exposed to an outside of the flotation tank and a second part extending into the flotation tank, a microbubble forming means positioned on or adjacent to the second part of the shell, and a treated water outlet connected to the flotation tank and configured to allow treated water separated from solids in the flotation tank to be discharged therethrough.
