Development of a Low-cost Automatic Water Quality Diagnosis System for Cooling Towers

Abstract

We developed a low-cost automatic diagnosis system for water quality in cooling towers to measure the concentrations of key ingredients such as Ca Experimental results showed that the accuracy of the proposed system is sufficiently high for water quality diagnosis and management of cooling towers, demonstrating the possibility of the proposed system's wide usage in real environments.Keywords: Water quality diagnosis, Low-cost spectrophotometer, Cooling tower management, Chemical concentration measurement 2013, Revised: Nov. 6, 2013, Jan. 8, 2014, Accepted: Jan. 13, 2014 This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http://creativecommons. org/licenses/bync/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.
