SLIME RISK EVALUATION METHOD, WATER QUALITY EVALUATION DEVICE, AND WATER TREATMENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a slime risk evaluation method capable of more accurate evaluation of slime tendency in a water treatment system.;SOLUTION: The slime risk evaluation method includes steps of: measuring a first ATP (adenosine-5'-triphosphate) value which is an ATP value of unheated raw water; measuring a second ATP value which is an ATP value of the raw water heated for a predetermined time; evaluating the number of bacteria in the raw water based on the first ATP value; evaluating nutrients in the raw water based on the difference between the first ATP value and the second ATP value; and evaluating the slime risk of the raw water based on the number of bacteria and the nutrient.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
