A system for extracting metals (e.g. precious metals or dangerous metals) from a substrate material such as sludge from a lake bed or sewage treatment facility includes processing the substrate material and metals by exposing the substrate material and metals to the plasma of an electric arc. Then, the exposed substrate material and metals are passed through an electrically charged collection grid in which the metals, now electrically charged, are attracted to the collection grid and hold to the collection grid and the substrate material exits the collection grid with less concentrations (or none) of the metals. In some embodiments, in addition to recovering the metals (e.g. precious metals, dangerous metals, etc.), a flammable gas is produced.

The present invention relates to a process for separating microplastics from aqueous matrices based on the interaction of said microplastics with magnetic minerals containing iron, such as magnetite, which gives rise to the formation of a microplastic/magnetic iron mineral aggregate that can be readily separated from the water by applying a magnetic field.

Provided is an apparatus for removing thermal stratification generated by turbulent penetration by using a rotation ring. The apparatus removes thermal stratification formed in a branch pipe branching from a main pipe through which a high-temperature fluid flows, the apparatus including: a hollow body portion coupled to the branch pipe; a plurality of first electromagnets provided to be spaced apart from each other in a circumferential direction of the body portion; a controller configured to sequentially change polarities of the plurality of first electromagnets; and a rotation ring including a plurality of second electromagnets having either an N polarity or an S polarity, the rotation ring being rotatably coupled to the body portion, wherein, when the polarities of the plurality of first electromagnets are sequentially changed, the rotation ring rotates according to a magnetic force of the plurality of first electromagnets and the plurality of second electromagnets.

Resources, such as water, energy, power, amount of de-scaling chemicals, device lifetimes, data analytics and system depreciation may be conserved through the use of dual-field electric and magnetic probes that create and apply electromagnetic fields to liquids, such as water.

The present invention relates to the field of water environment treatment, and particularly discloses a system and method for restoring a river and lake water body by a floating type water purification plant. The method comprises: (1) under the action of a water pump, enabling the river and lake water body to pass through a grille to be filtered; (2) lifting the filtered water body to an ss sedimentation tank by the water pump through a water inlet pipe, and carrying out pre-magnetization on the water body in the water inlet pipe by a pre-magnetization device arranged in the water inlet pipe; (3) enabling the water body subjected to pre-magnetization treatment to enter the ss sedimentation tank so as to remove particles in the water body; (4) enabling the water body treated by the ss sedimentation tank to enter a magnetizer to be subjected to magnetization treatment under a magnetic field intensity of 50 mT to 2,000 mT; and (5) distributing the water body subjected to magnetization treatment at the upper part of the floating type purification plant. According to the present invention, for the river and lake water body, for different growth periods of aquatic plants, the magnetic field intensity of the magnetizer for carrying out magnetization treatment on the water body is regulated for inducing growth of plants and beneficial indigenous microorganism communities, so that the purifying capacity and reliability of an ecological floating bed technology are reinforced.
