Abstract: 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.

Abstract: The disclosure provides a method and device for preparing slightly acidic electrolyzed water with a controllable and stable concentration. According to the method, a solution addition velocity of a first solution addition device is adjusted according to a difference between a detected voltage Udetected and a control voltage Ucontrol in an electrolytic cell, so that the first solution addition device adds an electrolyte stock solution to the electrolytic cell in real time, thereby preparing the slightly acidic electrolyzed water with a controllable and stable concentration. The device includes an electrolyte stock solution storage, an electrolytic cell and a first mixer connected sequentially. A first solution addition device is connected in series between the electrolyte stock solution storage and the electrolytic cell. The disclosure overcomes the defects of uncontrollable and unstable concentration in the preparation of present slightly acidic electrolyzed water.

Abstract: Provided is a tank sterilizer composed of a power supply part including an operation switch, and a sterilization part for sterilizing fluid in a tank, wherein a sterilization effect is maximized by generating microbubbles by electrolysis or electric discharge instead of killing bacteria by using a UV LAMP, an ozone lamp, and a pressure pump, and due to the coupling of a bubble generation module and a power connection module to each other by an electroconductive connector, a separate power connector is not required to be installed, whereby the tank sterilizer is simple in structure and is easy to be installed.

Abstract: A method of electro treating tailings in a containment structure to cause a separation of at least some water from said tailings and a consolidation and compaction of at least some solid particles is shown. The method includes placing a plurality of first electrodes in the tailings to be treated generally along one side of a predetermined volume and placing a plurality of second electrodes in the tailings to be treated generally along an opposite side of said volume to the plurality of first electrodes, said first and second electrodes being spaced apart by a predetermined distance. The next step is applying a treatment current across said distance between said spaced first and second electrodes to create an electrical field which causes solids to consolidate at one of said plurality of first and second electrodes; and creating a geotechnical structure within said volume comprised of dewatered solids consolidated from said tailings around one of said electrodes. The geotechnical structure may be a layer at the bottom of the containment structure, along a side of the containment structure or across the top of a containment structure.

Abstract: The present invention provides an oxidant production apparatus, an example embodiment of which comprises a water container configured to accept and retain a volume of water; a porous salt container configured to accept and retain a quantity of salt, mounted with the water container such that salt in the salt container is in fluid communication with water in the water container; an electrolysis system mounted with the water container; and a gas directing element mounted with the salt container and the water container such that gas generated by the electrolysis system is preferentially directed through the salt container. In operation, gas from electrolysis percolates through the water and the salt, agitating the salt and encouraging the salt to fully dissolve.

Abstract: For bio-electrically generating electric power from organic ingredients of a waste water flowing in a flow direction, an anode is immersed in the waste water in a first spatial area, and oxygen is supplied to a cathode which is electrically connected to the anode and arranged in a second spatial area delimited from the first spatial area by means of a proton-permeable membrane. A voltage between the anode and the cathode is increased by a DC/DC converter located at the anode and the cathode, and a further voltage between a further anode in said or a further first spatial area and a further cathode in said or a further second spatial area is increased by a further DC/DC converter located at the further anode and the further cathode. A DC voltage link is charged with the DC/DC converter and the further DC/DC converter connected in parallel to the DC voltage link.
