Abstract
PURPOSE: To remove contained salt and arsenic, silica, heavy metal, etc., by performing reverse permeation of high-temperature terrestrial-heat water, etc., by a semipermeable film obtained by sticking collidal moisture-containing oxide, etc., dynamically to the outside surface of a porous base of heat resistance.
CONSTITUTION: A reverse permeation element 3 made of a heat-resistive material, such as ceramics, is composed of a cylindrical porous base 11 closed at the tip and opened at the base end, and semipermeable film 14 consisting of the 1st thin film 12 and 2nd thin film 13 formed sticking on its outside surface. This film 14 is formed by supplying a solution of colloidal moisture-containing oxide, etc., (e.g., colloidal zirconium hydroxide) to a reverse permeation chamber 10 in a pressure container 1 under pressure. Then, 10W70kg/cm2, 70W95°C terrestrial-heat water, etc., supplied 4 into the container 1 is distributed from many pores of a distributing pipe 2 for distributing water to be treated into the chamber 10 uniformly. After the reverse permeation operation of the film 14, the permeating water is fed into the element 3 through the film 14 and discharged 5. On the other hand, the condensed terrestrial-heat water, etc., containing the said salt, etc., is discharged 6 via a water through hole 16.
