A surface treatment apparatus includes a treatment vessel including a treatment space in which a metal component is disposed, a spray nozzle that supplies mist of a non-chromate conversion treatment liquid to the treatment space, and a circulation device that collects the non-chromate conversion treatment liquid from the treatment space and supplies the non-chromate conversion treatment liquid to the spray nozzle.

Surface treatment apparatus and surface treatment method

A water treatment device is provided with a separation membrane device having a separation membrane for concentrating dissolved components and dispersed components from water to be treated and obtaining permeated water; a first deposit detecting unit provided in a non-permeated water branch line branched from a non-permeated water line for discharging non-permeated water in which dissolved components and dispersed components have been concentrated, using part of the non-permeated water that has branched off as a detection liquid, and having a first separation membrane for detection in which the detection liquid is separated into permeated water for detection and non-permeated water for detection; and first flow rate measuring devices for separated liquid for detection that measure the flow rates of one or both of the permeated water for detection and the non-permeated water for detection separated by the first separation membrane for detection.

Water treatment device and operating method for water treatment device

Provided is a sterilization device for a container which exhibits high sterilization performance while being low in cost. A heating medium is positioned in a sterilant passage so as to block the downstream end thereof in the direction in which the liquid sterilant is discharged. A ventilation passage is formed in the lateral surface of a tube body of a sterilant supply tube, on the upstream side in the direction in which the liquid sterilant is discharged in relation to the heating medium. A sterilant supply unit sterilizes the inner-peripheral surface of a container as a result of the sterilant vaporizing upon reaching the heating medium, leaking to the exterior via the ventilation passage formed in the lateral surface of the tube body, and adhering to the inner-peripheral surface of the container.
