The method comprises: enabling a water body in the natural environment to first pass through a filtering device to remove large-sized particles in the water body; enabling the filtered water body to pass through a water pipe provided with multiple stages of permanent magnets to be subjected to pre-magnetization; then enabling the water body subjected to pre-magnetization to enter an equalization tank to be subjected to homogenization and/or flocculating sedimentation to separate phytoplankton and suspended particles in the water body; then for different growth phases of the phytoplankton, applying different magnetic field intensities for inhibiting and even directly killing the phytoplankton to implement optimization of cost and effects; and finally, carrying out aeration oxygenation on the magnetized water body and releasing the water body subjected to aeration oxygenation into the natural water environment.

The present disclosure provides for methods and systems for separating ultrafine particulate pollutants from aqueous suspensions. The present disclosure provide for methods and systems that can reduce the amount of ultrafine particulate pollutants from aqueous solutions, for example storm water runoff, which are not readily or easily removed using current state of the art techniques. In general, methods of the present disclosure provide for removing a portion of target ultrafine particulate pollutants using magnetic nanoparticles, which form aggregates with the ultrafine particulate pollutants. After a time period a magnetic field is applied and the aggregate can be separated from the aqueous suspension. Subsequently, the aggregates can be broken down and the magnetic nanoparticles recycled or reused while the ultrafine particulate contaminants are further processed, recycled, or disposed of.

A water purification process for treating water containing at least some organic contaminants, and including the steps of pre-treating the water for capturing organic contaminants from solution in a water stream, by passing the water into a spin up bowl to speed up the water stream, forcing the high speed stream through an annular flow passage located centrally of the spin up bowl passing the high velocity stream between a magnetic member and a magnetic ring, thereafter passing the water stream into an energy recovery bowl, directing the flow from the flow passage onto a zinc anode member; and thereafter passing the water stream along a grounded pipe, thereby causing the development of fine particles of calcium carbonates, and capturing the organic contaminants

A process for treating acid mine drainage removes iron ions from the acid mine drainage in the form of zero-valent iron nanoparticles which can be subsequently used for environmental remediation.

According to the present invention, a magnetized water generator is provided, comprising: a housing portion having a cylindrical structure; a first magnetized water generating unit located on an upper side in the housing portion and rotating in a forward or counterclockwise direction by water flowing into the housing portion so as to magnetize water; and, a second magnetized water generating unit located on an intermediate position in the housing portion, wherein the second magnetized water generating unit is separated from the first magnetized water generating unit by a barrier and wherein the second magnetized water generating unit rotates in a reverse or clockwise direction so as to magnetize the water that has been magnetized by the first magnetized water generating unit and has passed through said barrier

The present invention relates to a groundwater circulation well system with pressure-adjustable hydrodynamic cavitation, including a circulation well body, a sucked and injected water circulation assembly and a hydrodynamic cavitator. The sucked and injected water circulation assembly is based on a water suction and injection pump. The hydrodynamic cavitator is provided, inside a vortex chamber, with a vortex water inlet column capable of changing a water passing aperture. The hydrodynamic cavitator is capable of changing a bubbling pressure and a breaking pressure of hydrodynamic cavitation bubbles in the vortex water inlet column. The hydrodynamic cavitator generates vortices in the circulation well body to accelerate uniform mixing of a remediation agent and the groundwater. Energy from collapsing and bursting of the hydrodynamic cavitation bubbles activates the remediation agent such that contaminants in the groundwater are efficiently degraded.
