ABSTRACT

 

Water purification is important because water is a basic necessity of life. Chlorine is used for disinfection in water purification. Monitoring the levels of chlorine is necessary in order to maintain level of purity of potable water. Hence, different methods of testing can be used to monitor the level of residual chlorine in water. This paper proposes a method to monitor the residual chlorine percentage in water using an advancement in the Orthotolidine (OTD) testing method by application of digital image processing RGB model. The image of chlorinated water after adding OTD solution is provided as input to the system to detect the residual chlorine percentage in potable water. The method uses two features of the image: the intensity levels of the pixels of the RGB planes and the standard deviation of the intensity levels. This technique is very useful for all urban and rural water supply system for easy determination of residual chlorine.
