  • Mar 2013
Six community water treatment systems were visited between August and November 2012. Only one system had permanent operators at the treatment plant. Operators intermittently worked at the other plants. The quality of raw water and flows varied widely across the six plants. Treatment operation procedures were not properly followed in all systems. On...

... Hach portable chlorine meter was used for free chlorine measurements and Coli-scan Easy Gel method was used for analyzing E-coli levels. The results are given below in Table 1.2. Preliminary tests with this sample size for each plant in a day will not provide conclusive information trends. ...

... contrast, the TAO system faces a number of management, supervision, and quality control challenges. One factor is the overlapping responsibilities between departments within the Royal Thai Government (RTG). The Department of Water Resources (DWR) within the new Ministry of Natural Resources and Environment is responsible for the development and dissemination of treatment handbooks and guidelines as well as providing training. DWR has trained 2 operators from each TAO -totally 3000 countrywide as of 2008 (Juntopas and Naruchaikusol, 2011). However, during visits to various community treatment systems throughout Tak Province, none of the operators appeared to have received the training from DWR and, moreover, competency levels of the operators in the water treatment systems vary widely between different TAOs ...

As turbidity level gets above the standard, it requires more disinfection chemical to be employed to remove bacteria from the final water, with less assurance of disinfection effectiveness. ...
