CHEMICAL AGENT FEEDING DEVICE

WIPO Patent Application WO/2019/146394

A1

A chemical agent feeding device (100) in which a dispersion material (F) and a chemical agent (CA) are provided in a chemical agent tank (21). The dispersion material (F) has dispersed gaps, and causes water (W) being treated to disperse on the inside of the chemical agent tank (21). The pore diameter of a permeable membrane (42) is such that the chemical agent (CA) supported by the permeable membrane (42) is prevented from permeating before the water (W) being treated permeates through the permeable membrane (42) and comes into contact with the chemical agent (CA). The pore diameter of the permeable membrane (42) is such that the chemical agent (CA) contained in the water (W) being treated can permeate after the water (W) being treated has permeated through the permeable membrane (42) and come into contact with the chemical agent (CA). The dispersed gaps of the dispersion material (F) are in a state that allows the water (W) being treated containing the chemical agent (CA) to flow to at least one through hole (21A).
