| Abstract: | This paper introduces two sorts of available methods apply to the on-line automatic meters of ABB-8232 and Seres2000. One is decreasing the concentration of NaOH to 5.0% and increasing the concentration of EDTA to 3.57%; The other is altering a part of liquid pipe of TOC meter. Then, the period of artificial cleaning can extend and the cost of maintenance can be reduced. |
