A water reclamation method on the basis of integrated use of magnetic resin adsorption and electrosorption is provided. It belongs to the water reclamation field, including the following steps: pump the biotreated effluent into a reactor that is filled with magnetic resin particles so that the chromaticity, organic pollutants, total nitrogen, total phosphorus contained in the wastewater can be effectively reduced; channel the fully reacted mixture into a precipitation tank for separation; part of the separated magnetic resin is pumped back into the reactor while the rest of the separated magnetic resin flows into a regeneration tank; the wastewater treated by magnetic resin adsorption then flows into an electrosorption unit for a desalting process; the remaining organic pollutants and inorganic pollutants are further removed.

Methods and systems for acid regeneration of ion exchange resins are disclosed. Acid resins designed for use in a variety of cleaning application using a water source use a treated, softened, acidic water source according to the invention. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.

A salt water supply unit includes a salt water plate that divides the interior of a salt water tank into a salt container and a salt water reservoir, and a salt water well that stands and penetrates the salt water plate. The salt water well accommodates a salt water valve device and a concentration detector. The salt water valve device includes a valve box having a valve hole that allows makeup water or salt water to flow therethrough, a float rod penetrating the valve hole, a valve element coupled to a first end of the float rod, and a water level detecting float coupled to a second end of the float rod. The concentration detector includes a switch that is incorporated in a stem holding a concentration detecting float. The switch outputs different detection signals in accordance with the position of the concentration detecting float.

A water softener apparatus comprising a housing having a chamber for accommodating at least one compressed salt block having an elongated block form, the configuration accommodating the compressed salt block within the chamber with its longitudinal axis in a vertical orientation. The water softener apparatus includes a manually detachable front cover enclosing the chamber and a non-touch salt level indicator device arranged in or on the front cover of the housing above the chamber to determine a salt level from an upper end face of the compressed salt block accommodated in the chamber, the non-touch salt level indicator device determining the salt level from the upper end face of the compressed salt block through a wall of the front cover of the housing. The non-touch salt level indicator device is a battery powered device and the water softener apparatus is a non-electric powered water softener apparatus.
