Disinfection

An overview of disinfection, complete with example problems, as typically delivered in Clemson's EES 3030 Water Treatment Systems course in the Department of Environmental Engineering and Earth Sciences. The content follows Chapter 10 of the textbook "Water and Wastewater Engineering" by Mackenzie L. Davis.
Specific topics covered include history of disinfection, regulations, chlorine reactions in water, acid/base chemistry, chloramines, ozone, chlorine dioxide, UV, disinfection byproducts, disinfection kinetics, contactor design, the CT concept, chlorine demand, chlorine decay, and choosing an appropriate disinfectant.

Thanks a lot! It's very didactic!

Very helpful. However once I thought of how much you sound like Paul Rudd in this video, I’ve been distracted and waiting for this to turn into a skit.

Sorry but chapter 10 of the book is titled filtration and not disinfection

Hi David Ladner. Just a quick question. I have a larrge pond, that has alklainity of 100ppm, pH of 8.5, and is filled with bacteria. I am planning to add calcium hypochlorite into it. I understand at high pH most of the form of the hypochlorite ion will be in the less favourable form, hypochlorite, and very little hypochlorous acid will be there. Now, since hypochlorous acid is much much more effiecent (80x) at kiling bacteria, i assume once added, its concentration will be depleted quite quick. Since it is in equilibrium with hypochlorite ion and H+, so wont the equilibrium respond by shifting left, thus increasing the concentration of the hypochlorous acid and thus reducing the concentration of the hypochlorite ion?

After how long after giving chlorine dose in 1 liter jar, residule chlorine is checked

It was helpful to understand scaling/fouling Can I get full access to your lectures?
