Abstract: A method for controlling a liquid treatment apparatus of the present disclosure includes: (i) providing the liquid treatment apparatus; (ii) treating a polluted liquid in a photocatalytic reaction tank by a photocatalytic reaction to produce a treated liquid; (iii) introducing a liquid mixture into a separation tank from the photocatalytic reaction tank through a feed passage by a circulation pump; (iv) introducing a filtrate to an outside of the separation tank through an extraction passage while filtering the liquid mixture introduced into the separation tank by a filtration membrane, and feeding the liquid mixture to the photocatalytic reaction tank through an overflow passage; and (v) making a flow rate of the liquid mixture measured by a liquid mixture flow meter higher than a flow rate of the filtrate measured by a filtrate flow meter by controlling the circulation pump by a controller.

Abstract: A liquid treatment apparatus includes a housing for storing a liquid, a first electrode at least part of which is arranged in the housing, a second electrode, a third electrode, a first power supply that, in operation, applies a first voltage between the first electrode and the second electrode to make the first electrode held effectively positive with respect to the second electrode, and a second power supply that, in operation, applies a second voltage between the second electrode and the third electrode to make the third electrode held effectively negative with respect to the second electrode. Plasma is generated inside a bubble, which is present in the liquid, when the liquid is stored in the housing and the first power supply applies the first voltage between the first electrode and the second electrode.
