Workshops for Water & Wastewater Operators



Disinfection Alternative Operations for Water and Wastewater Systems


(I) Welcome aboard as we take the small water/wastewater system operator on a voyage into the alternatives to the industry standard Chlorine for primary disinfection of drinking water and treated wastewater.

(II) The killing of bacteria, viruses, and protozoan has been the assigned task of Chlorine by gas, liquid, and solid Hypochlorite since the turn of the twentieth century. But over the past 15 years, we have come to realize that in addition to its microbe destroying power, it also reacts with many organic compounds producing Trihalomethanes, or THM's, potential carcinogens. Treated wastewater effluents, high in residual Chlorine expose the receiving stream aquatic life to potential long term harm.

(III) First, journey into a world of chlorine derivatives that are quickly becoming favorite alternatives to Chlorine. Tour the pros and cons of Chlorine Dioxide and Chloramines as alternatives to help reduce reaction byproducts. Explore the safety, cost issues, monitoring requirements necessary to adequately dispense and control these choices.

(IV) Our expedition takes the high road into exploration of the benefits and features of alternative disinfectants like Ozone, Ultraviolet, Miox , Ultra-filtration, and other disinfectants. Learn how we rediscovered the benefits of UV in recycled water and how the word "Dechlorination" is quickly disappearing from our wastewater vocabulary. Your adventure continues as we look into the disadvantages these options pose and filter out the mystery behind why some of these systems are fast becoming the favorite alternative while others lose popularity.

(V) Our adventurous look into disinfection leaves the operator with only one final thought, This presentation really is all about choices!
