2008 Technical Training Workshops

Chloramination & Chlorine Disinfection
This class is designed with three main objectives. First, it gives a general understanding of basic water analysis, including sampling protocol, procedures, and the use of standards. Second, a basic overview of water disinfection using chlorine and the conversion to monochloramine as
the primary disinfectant is presented. Last, participants are allowed to gain hands-on experience in running some colorimetric methods relevant to the chloramination disinfection scheme. The lab portion will focus on analysis of total chlorine, monochloramine/free ammonia, and nitrite. See the latest 2008 regional workshops on Hach.com.
