A monitored inline hard water processing assembly for conditioning hard water includes a cannister, which is cathodic, a disc, and a rod, which is anodic. The disc is removably couplable to a top of the cannister. The disc has a pair of channels positioned therethrough, each of which is in fluidic communication with an interior space defined by the cannister. The rod is removably couplable to the disc so that the rod is electrically insulated from the disc and extends into the interior space. A monitoring unit, which is electrically coupled to the cannister and the rod, is operationally couplable to a source of electrical current to provide a flow of direct current through the rod, the cannister, and water flowing therethrough. The monitoring unit comprises an indicator, which can indicate at least two resistance states of the rod.

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.

The present invention belongs to the technical field of water treatment, and in particular to a magnetic powder strengthened method for removing nitrate nitrogen and inorganic phosphorus, which includes the following steps: (1) mixing permanent magnetic material powder with paramagnetic Fe3O4 powder, and magnetizing the mixture in a magnetic field to prepare magnetic powder; (2) adding the magnetic powder directly or in a form of granular filler into a water treatment reaction vessel; and (3) allowing the to-be-treated water to enter the water treatment reaction vessel, performing a chemical reaction of removing nitrate nitrogen and inorganic phosphorus in the presence of a reducing agent, and discharging the water after the reaction is completed. By adopting the method of the present invention, a uniform and fine magnetic field can be provided, thus the reaction efficiency is improved, and the process is simplified and the cost is lowered.
