Abstract: A water treatment device includes a grounding electrode having a planar flowing water portion that causes treatment target water to flow, a multiple of wire form high voltage electrodes provided parallel with the flowing water portion in a position distanced from the flowing water portion of the grounding electrode and to extend in a direction intersecting a flow direction of the treatment target water, and a blowing device that forms a gas flow that intersects an extension direction of the high voltage electrode and intersects an extension direction of an electrical discharge. This kind of configuration is such that even when water droplets adhere to the high voltage electrode, the water droplets are blown away by a pressure of the gas flow formed by the blowing device, and a spark discharge is restricted.

Abstract: One of the purposes is to provide a pulse discharge power supply for use in generating pulse discharge. The pulse discharge power supply includes a pulse generation unit, a control circuit, an electric current detector and an electric current signal processing unit. The pulse generation unit generates a first pulse, and applies it to a discharge load for generating pulse discharge. The electric current detector detects an electric current flowing into the discharge load in accordance with the application of the pulse. The electric current signal processing unit outputs into the control circuit a signal based on an integration result of the electric current having been detected. The control circuit controls the generation of a second pulse in the pulse generation unit based on the signal being received.

Abstract: When mineral components such as calcium carbonate and magnesium are contained in humidifying water and a humidification plate has holes and high humidifying efficiency, scales may be locally generated at an end or vicinities of the holes on a windward side. When minute voids in the humidification plate are clogged due to the scales, water absorption capability at a scale generation region is significantly reduced. A problem can arise requiring to replace the humidification plate even when a region other than the end and the vicinities of the holes is satisfactory, whereby replacement cycles are shortened. To address the problem, plural openings in a plate thickness direction are distributed on a flat plate surface of a water absorbing humidifying material. Thus, in an airflow direction of air sent from end sides of the water absorbing humidifying material, opening areas of the plural openings on one end side are increased.

Abstract: A water treatment system includes: an aeration tank for converting wastewater containing organic substances into sludge-laden treated water by aerobic treatment; an ozone supply unit for feeding ozone into the sludge-laden treated water drawn out from the aeration tank; and a bubble detector for detecting the condition of bubbles produced by reaction between the fed ozone and the sludge. The ozone treatment is controlled by utilizing as an indicator for sludge volume reduction effect the increase rate of bubbles detected by the bubble detector, so that the water treatment system is able to vary the amount of ozone feed depending on the conditions of water treatment.

Abstract: In a water treatment apparatus, a tilted plate is disposed at an incline relative to a horizontal plane. Water to be treated is passed over the upper surface of the tilted plate. A discharge forming body is disposed across a gas layer above a water film formed by the water to be treated flowing over the tilted plate. A droplet forming apparatus exerts power on the water film so that at least some of the water to be treated shoots upward in the form of droplets.

Abstract: A water treatment apparatus includes: a trough-shaped flow path portion (2) on which treatment target water (W) flows; a high-voltage portion (3) having a plurality of high-voltage electrodes (4) disposed above the flow path portion (2) spacing therebetween in a direction orthogonal to a direction in which the treatment target water (W) flows; and an electric field relaxation portion (5) having first members (6) and second members (7) provided so as to extend around the high-voltage portion (3). Water treatment is performed by applying a high voltage from a pulse power supply (8) to the high-voltage portion (3), the first members (6), and the second members (7) in order to generate electric discharge between the high-voltage electrodes (4) and the flow path portion (2). And water treatment is performed by dissolving generated active species such as ozone and hydroxyl radicals into the treatment target water.
