ION ABSORBENT, MANUFACTURING METHOD OF ION ABSORBENT AND APPLICATION METHOD OF ION ABSORBENT

摘要

PROBLEM TO BE SOLVED: To provide an ion absorbent, a manufacturing method thereof and an application method of the ion absorbent.;SOLUTION: The ion absorbent has active charcoal (degraded charcoal) used in a water treatment process and the degraded charcoal is a dried article with moisture content of 20 mass% or less. Because excess moisture is removed and weight is reduced with the moisture content of 20 mass% or less, transport efficiency is high. A biofilm is formed on the degraded charcoal, the biofilm has ion absorptive performance. Therefore the ion absorbent can be used for absorption removal of various ions such as ammonium ion.;SELECTED DRAWING: Figure 3;COPYRIGHT: (C)2018,JPO&INPIT
