A water disinfection system preferably includes a battery compartment, a control printed circuit board (PCB) to manage several parameters including timing, voltage rate, and user-interface. A high voltage power supply is coupled to a set of electrodes to cause an electric discharge. The electric discharge results in a series of reactions in the water that eliminate bacteria and viruses, dissolves organic material, and oxidizes inorganic compounds.

A novel cell for generating ozonated water, the cell comprises a nafion membrane separating a diamond coated anode, and a gold surfaced cathode enclosed within a cell housing with the catalyst side of the nafion membrane facing the cathode. The cell housing has a cathode housing portion and an anode housing portion separated by the membrane, each housing portion having ridges to enhance substantially even flow of fluid over the cathode and anode. The housing portions contain O-rings in grooves to prevent leaks, and alignment features to keep the electrodes aligned. The cathode and anode have an array of holes allowing fluid to penetrate to the surface of the niobium membrane. Input ports allow fluid to flow into the housing and over the anode and cathode and then out of the housing through outlet ports. The housing may also incorporate an integrated spectral photometer including a bubble trap.

A versatile sanitizing and cleaning apparatus (10) has a reservoir (30), a removable base (40) at the bottom of the reservoir having electrodes (52, 54) that extend up into the reservoir (30) for electrolyzing water within the reservoir, and an opening (32) at the top end of the reservoir. A cap (60) having a valve (61) that is biased to the normally-closed position screws to the top of the reservoir (30), allowing the reservoir to be turned upside-down and inserted into a receiving portion (22) of a mop, thus allowing the mop (12) to use electrolyzed water for cleaning. Alternatively, instead of being used with the cap (60) and mop (12), the reservoir (30) and base (40) can be mated with a hand sprayer (64) allowing the reservoir (30), base (40), and hand sprayer (64) to be used as a spray bottle (69) to spray electrolyzed water for cleaning purposes.

A neutralization cell is provided which may be used to increase a pH level of a chlorine solution. The neutralization cell includes a neutralization anode, a neutralization cathode, an inlet, and an outlet. The neutralization anode and the neutralization cathode are positioned to divide the neutralization cell into a middle area between the neutralization anode and the neutralization cathode, an anode area on a side of the neutralization anode furthest from the neutralization cathode, and a cathode area on a side of the neutralization cathode furthest from the neutralization anode. The inlet directs the chlorine solution into the neutralization cell by directing an incoming flow of the chlorine solution into the anode area. The outlet directs the chlorine solution out of the neutralization cell by directing an outgoing flow of the chlorine solution from the cathode area.

An electrochemical membrane module for selectively removing pollutants and a preparation method thereof are provided. A Ti/SnO.sub.2Sb substrate electrode is coated with a MI-TiO.sub.2 sol-gel by means of a dip-coating method, and then sintered to obtain a molecular imprinting type Ti/MI-TiO.sub.2/SnO.sub.2Sb coated electrode; the coated electrode is adhered to a ceramic micro-filtration membrane using epoxy resin glue to obtain a Ti/MI-TiO.sub.2/SnO.sub.2Sb MI-anodic conductive composite membrane; the MI-anodic conductive composite membrane is used as an anode, and a titanium mesh is used as a cathode, so that the electrochemical membrane module capable of selectively removing pollutants is obtained. The invention effectively combines an electrochemical micro-filtration membrane and a molecular imprinting technique. When the electrochemical membrane module is used, suspended particles and refractory organics in the sewage are removed, and a highly selective removal of certain refractory pollutants can be achieved.

A water treatment system includes: a water treatment device; a feed-water pump that feeds water to be treated to the water treatment device; an ozone generator that generates ozone-containing gas containing ozone gas and oxygen gas; and a direct-current power supply that supplies direct-current power.
