A switching valve device for switching an intermediate flow path through which a fluid flows from an inlet to an outlet includes: a first valve which switches a flow path extending from the inlet to one of two flow paths; and a second valve which is provided on a downstream side of the first valve and switches the intermediate flow path by a differential pressure generated by depressurization in an external flow path Lout connected to the intermediate flow path connected to one of the two flow paths.

Switching valve device

A membrane element having a filtration main body, a header (a water collection portion) that collects treated water from an end portion of the filtration main body and a treated water lead-out portion that leads out the treated water is used. The treated water lead-out portion is connected to a tubular peripheral wall of a water collection pipe that collects treated water solid-liquid-separated by the membrane element, and communicates with an inside of the tubular peripheral wall. The tubular peripheral wall has a thick portion that is thicker in a horizontal direction at an upper-side peripheral wall portion located at an upper side (or at a lower-side peripheral wall portion located at a lower side) in the radial direction of the tubular peripheral wall, and a connecting hole that penetrates the thick portion.

Connection structure and membrane filtration device

A bubble generation device intermittently generates large bubbles in a liquid phase. The bubble generation device includes a bubble storing container, a pivot, and a pair of edge portion receivers. The bubble storing container stores bubbles generated by a gas supply nozzle in the liquid. The pivot allows the bubble storing container to pivot thereon, thereby releasing the large bubbles from the bubble storing container. The pair of edge portion receivers receives and blocks an edge portion of the bubble storing container to limit pivot of the bubble storing container. An inside of the bubble storing container is partitioned by a partition that is installed in an axial direction of the pivot.

Disclosed is an apparatus for water treatment, including a membrane separator for solid-liquid separation; and a particle fractionator which has at least two exits of a fractionated solid-liquid mixture produced therein, wherein a liquor containing particles of different sizes including submicron particles is fed to the particle fractionator before a membrane separation by the membrane separator, and wherein a first fraction of the fractionated solid-liquid mixture is returned to the membrane separator from one exit of the at least two exits of the particle fractionator, the first fraction being less than the liquor in terms of content of the submicron particles. This apparatus enables a rapid achievement of suppression of membrane fouling.

A solid dialysis A agent is provided, which is to be used in preparing a bicarbonate dialysis fluid, wherein: the solid dialysis A agent contains glucose, acetic acid and an acetate salt; at least a part of a mixture of the acetic acid with the acetate salt is an alkali metal diacetate; and the acetic acid/acetate salt molar ratio is adjusted to 1/0.5 to 1/2. This solid dialysis A agent makes it possible to prepare a bicarbonate dialysis fluid which has a total acetate ion concentration of 2 to less than 6 mEq/L. Further, the dialysis A agent exhibits excellent stability of ingredients and a reduced acetic acid odor.

A dialysis agent A including a mixture containing glucose, acetic acid, and acetate salt, but not sodium bicarbonate, wherein the molar ratio of acetic acid:acetate salt is 1:0.5 to 1:2, and wherein a total amount of the acetic acid and acetate salt contained in the dialysis agent A is between 2 mEq/L and 6 mEq/L when the dialysis agent A is dissolved in 1 L of a bicarbonate dialysate.

Dialysis agent a containing acetic acid and acetate salt, and a two-part dialysis agent using thereof

The purpose of the present invention is to provide a dialysis agent A, which is able to set the total acetate ion content in the dialysate to a low value, excellent in storage stability of glucose, able to reduce the acetic acid odor, and able to suppress the corrosion of the dialysate delivery system and the dialysis machine, as well as to provide a two pack type dialysis agent utilizing the dialysis agent A. In the dialysis agent A used in the preparation of a bicarbonate dialysate, which is used as one part of a two pack type dialysis agent, it becomes possible to prepare a bicarbonate dialysate having the total acetate ion concentration of between 2 mEq/L or more and less than 6 mEq/L by allowing to include glucose, acetic acid and acetate salt and to satisfy the molar ratio of 1:0.5 to 2 of acetic acid and acetate salt, and include acetic acid and acetate salt in a total amount of between 2 mEq or more and less than 6 mEq in the dialysis agent A required to prepare 1 L of the bicarbonate dialysate. Moreover, according to the dialysis agent A, in addition to the excellent stability of glucose, it is possible to reduce the acetic acid odor, and furthermore possible to suppress the corrosion of the dialysate delivery system and the dialysis machine.

Technology for preparing a dialysis fluid capable of flexibly changing bicarbonate ion concentration and maintaining concentrations of electrolytes such as potassium, calcium, and magnesium at constant levels during dialysis according to the disease state of a patient. A three-component dialysate containing an agent S containing sodium chloride, an agent B containing sodium bicarbonate, and an agent A containing electrolyte components other than sodium chloride and sodium bicarbonate, with suitable adjustment of the amount of the agent B during dialysis fluid preparation maintains concentrations of trace metal ions such as potassium ions, calcium ions, and magnesium ions in a dialysis fluid at constant levels and flexibly changes the bicarbonate ion concentration therein. Adjusting the ratio between the amount of the agent S and agent B when the dialysate is used also makes it possible to maintain the sodium ion concentration at a constant level or flexibly change the sodium ion concentration.
