Document Type and Number:
Japanese Patent JP2023149145
Kind Code:
A
Abstract:
To provide a method of treating water to be treated, capable of preventing deterioration of the quality of water to be treated flowing in a bilayer type resin tower.SOLUTION: The method of treating water to be treated comprises steps of forming a first packed layer 41 that comes in contact with water to be treated and includes first resin particles 41A in a cylindrical tower body 31, arranging a water-permeable partition member 50 formed of a material flexible to the extent of being able to elastically deform according to the weight of second resin particles 42A different from the first resin particles 41A, on the first packed layer 41 in a condition of not being restricted by the tower body 31, and forming a second packed layer 42 including the second resin particles 42A on the partition member 50. The water to be treated is made to flow inside the tower body 31 from upside to downside.SELECTED DRAWING: Figure 2
