A water treatment system, particularly pre-filtration unit of the water treatment system, comprising at least one chlorine sensor device, includes a salt-water treatment device which is connected to the chlorine sensor device, an electrolysis cell being disposed in the associated line, and thereafter a pump and a release valve.

A self contained, automatic water quality monitoring and treatment system includes a water quality interface control module having a signal processor configured to: receive signaling containing information about a baseline test of pH and ORP levels of water to be monitored and also about a subsequent test of the pH and ORP levels of water to be monitored later in time to the baseline test; determine corresponding signaling containing information about the quality of the water being monitored based upon a percentage of change between the baseline test and the subsequent test later in time to the baseline of the pH and ORP levels of water being monitored; and provide the corresponding signaling for remote awareness, including wireless signaling for providing mobile or Internet awareness, and/or for controlling the treatment of the water being monitored.

An apparatus includes a reservoir for an aqueous salt solution, at least two electrodes spaced apart from each other integrated into the reservoir, a control module electrically coupled to the at least two electrodes, wherein the control module controls application of electricity to cause a first one of the at least two electrodes to be positively charged and a second one of the at least two electrodes to be negatively charged, and an impeller disposed in the reservoir for mixing the aqueous salt solution in the reservoir.

A wastewater treatment system and method for remediating wastewater and human waste that is self-contained and that has no connection to a municipal wastewater system and no connection to an electrical grid. The domestic toilet and wastewater treatment system can be powered by a photovoltaic panel as a source of electricity. The system includes an electrochemical cell that allows a waste stream to be disinfected in a few hours to a condition where no viable bacterial colonies can be cultured. The system produces a liquid stream that is suitable for system flushing or for uses in which non-potable water is acceptable. The system can generate hydrogen as a product that can be used to generate power. The system can generate nitrate, urea, ammonia and phosphate for use as fertilizer. The disinfected residual organic solids are also completely disinfected for potential use as an organic soil amendment for agriculture.

There is described a water monitoring device for monitoring a body of water. The body of water comprises a main body of water and a water inlet and/or water outlet. The water monitoring device comprises a sensor operable to generate data in relation to a property of the body of water, an attachment member operable to removably arrange the device in a substantially stationary position adjacent to the water inlet and/or water outlet of the body of water; and a communication member operable to transmit the data relating to a property of the body of water to a remote device. Also described is a water monitoring apparatus and a method of monitoring a body of water.

Container treatment plant for treating containers, such as bottles, in the beverage processing industry comprising a chlorine dioxide producer, a chlorine dioxide consumer, comprising at least one container treatment machine, in particular a pasteurizer, such as a tunnel pasteurizer, and a metering device that can introduce a solution containing chlorine dioxide produced in the chlorine dioxide producer into the chlorine dioxide consumer, where the chlorine dioxide producer is configured to produce chlorine dioxide through a reaction of sodium chlorite and sulfuric acid.

The present invention is a water purification system and method including a treatment tank with a water inlet, a chlorine source, and a heating element; at least one storage tank with at least one treated water outlet between the treatment tank and the storage tank(s) through which treated water passes therebetween, and a final water outlet(s) through which treated water leaves the system for the benefit of the end user. A power source powers all elements that require power, such as the heating element.

A magnetized water generating device includes a tube body 110 being filled with water; an induction coil 120 installed at a center inside the tube body 110; and a plurality of heating plates 130, 140 arranged around the induction coil 120. The magnetized water generating device further includes a high frequency generator 180 for applying high-frequency power to the induction coil 120 to heat the plurality of heating plates 130, 140, resulting in that the water in the tube body 110 is heated and converted into micro-cluster magnetized water; and a tube 150, positioned between a pair of magnets 160, 170 for causing the micro-cluster magnetized water to pass through an N-pole and an S-pole resulting from the pair of magnets 160, 170, thereby providing it as magnetized water exhibiting a high degree of electric conductivity.

The present disclosure is directed to a method of water treatment. The water is passed through an electrolytic cell which converts available chlorides to hypochlorous acid, hydroxyl radicals, or other oxidizing agents. The acid is used to reduce the chemical oxygen demand (COD), the biochemical oxygen demand (BOD), and/or the ammonia content of the water. In the absence of sufficient available chlorides, the water inlet stream may be dosed with a chloride solution (e.g. brine).
