Abstract: A water treatment plant which performs water treatment using a water treatment device includes an imaging device, a processing device, and a control device. The imaging device images a water treatment environment of the water treatment device and outputs image data obtained by imaging. The processing device causes an arithmetic device which performs an arithmetic operation using one or more calculation models generated by machine learning to execute the arithmetic operation employing the image data output from the imaging device as input data of the one or more calculation models. The control device controls the water treatment device on the basis of output information output from the arithmetic device by executing the arithmetic operation.

Abstract: A water treatment membrane washing apparatus includes two ozone dissolving tanks for storing filtrate generated by filtering raw water through a water treatment membrane and gas aspirators provided for the respective ozone dissolving tanks, for mixing the filtrate with ozone gas supplied from an ozone supply unit to generate ozone gas containing filtrate, and is configured such that waste ozone gas generated in one of the ozone dissolving tanks is aspirated by the gas aspirator provided for the other ozone dissolving tank. After the filtrate from the raw water is pretreated by being mixed with the waste ozone gas in the aspirator, the pretreated filtrate is mixed with the ozone gas in the other ozone dissolving tank until it reaches a predetermined concentration. The ozone gas containing filtrate is supplied from the secondary side of the water treatment membrane to the primary side thereof to wash the eater treatment membrane.

Abstract: A water treatment device in which a treatment target water introduction portion is provided in an upper portion of a receptacle, and the water treatment device has a space in which conductive porous members are not disposed between the conductive porous members and the treatment target water introduction portion in the receptacle. When a backwashing fluid is introduced from a lower portion of the receptacle in a desorption, the conductive porous members flow and are agitated owing to the backwashing fluid, because of which a desorption of ions adsorbed to the conductive porous members is promoted. Grains of the agitated conductive porous members collide with other grains of the conductive porous members or with electrodes or a separator, whereby scale and a biofilm appearing on surfaces of the grains of the conductive porous members, the electrodes, or the separator can be removed, and desalination efficiency can be maintained.
