Discussion 1.2

1)Conventional drinking water treatment involves a variety of physico-chemical processes as depicted in this course. Please explain the rationale for the treatment train commonly employed by full-scale drinking water treatment plants, i.e., coagulation-sedimentation-filtration-disinfection.

 

(Hint:  Why is coagulation placed before other processes? Similarly, why does disinfection situate at the end?)

 


2)Chlorine disinfection inactivates waterborne pathogens by utilizing the oxidation potential of free chlorine or hypochlorite. In contrast, membrane filtration is capable of directly eliminating pathogens by the physical sieving effect. In your opinion, what would be the pros and cons of the two technologies for the disinfection of drinking water? Furthermore, is there an approach to combine the two technologies to achieve better water quality? Please draw a diagram to explain your idea.

 

(Hint:  Remember the occurrences of disinfection by-products and re-contamination.)
