Abstract: A water treatment device generates a bubble in water to be treated inside a treatment tank, and treats the water to be treated through use of radicals that are generated by bubble electric discharge caused via the bubble. The water treatment device includes main electrodes for forming a main discharge area between a first main electrode and a second main electrode, auxiliary electrodes for forming a preliminary discharge area between a first auxiliary electrode and a second auxiliary electrode, and a bubble generator generating a bubble in water to be treated through use of an externally supplied gas. When a bubble generated by the bubble generator passes through the preliminary discharge area, discharge is caused via the bubble, and, when the bubble in an excited state subsequently passes through the main discharge area, the bubble causes discharge again to generate radicals.

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: 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 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.
