Ozone Disinfection of Re-claimed Wastewater

The goal of water disinfection is the inactivation of microorganisms, such as viruses, bacteria and protozoa, which can cause serious illnesses and death. Although disinfection can be accomplished to a significant extent by a number of physiochemical water treatment processes, such as coagulation, sedimentation, filtration, lime-soda softening and adsorption, a specific chemical disinfection step is usually incorporated into surface water treatment process trains to prevent the transmission of waterborne diseases.

Disinfection Basics CEU Training Course This course will cover the fundamentals of water disinfection beginning with the different and alternative water disinfectants and ending with the biological analysis of the water, insuring that the water meets federal compliance. Task Analysis and Training Needs Assessments have been conducted to determine or set Needs-To-Know for this course. The goal of this CEU Course is to provide awareness training to help workers recognize the occupational hazards and health effects of different disinfectants, halogens, chlorine exposure and the exposure controls; and to familiarize the participants with the properties and safe handling of chlorine - solid, liquid, gas, and the operation of gas chlorinators and other related equipment.

. Explain the general purpose and regulatory requirements of the disinfection process. . List bacteria, viruses and intestinal parasites that contaminate drinking water. . List factors that influence disinfection and explain how they influence it. . List five types of chemical disinfectants and explain the advantages and disadvantages of each. . Explain how irradiation is used as a disinfection process.

Recent studies have shown the formation of bromate in desalination-derived drinking water, especially when the desalinated water is treated with sodium hypochlorite solution produced by electrolyzing seawater.
