Rule 15-18-77-6.1.2 - Definitions1. Advanced Treatment System (ATS) - An Individual On-site Wastewater Disposal System that treats and complies with Section 41-67-10. Section 41-67-2(a)2. Chlorine - a highly irritating, greenish-yellow gaseous halogen, capable of combining with nearly all other elements, produced principally by electrolysis of sodium chloride and used widely to purify water, as a disinfectant and bleaching agent, and in the manufacture of many important compounds including chloroform and carbon tetrachloride.3. Chlorinator - a device that allows the treated effluent to pass around and over calcium hypochlorite tablets or the treated effluent is dosed with a specific amount of liquid chlorine by the use of an approved dispersal method.4. Chlorine Contact Chamber -chamber designed to provide a minimum of 1 hour detention time at the peak design flow. 5. Chlorine (liquid) - an aqueous solution of calcium hypochlorite used as a disinfection agent.6. Chlorine (tablet) - a solid form of calcium hypochlorite, a common disinfectant. These tablets dissolve in the wastewater, releasing the hypochlorite, which then becomes hypochlorous acid, the primary disinfectant.7. Chlorine Residual - free chlorine remaining after the chlorination process has occurred.8. Disinfection - treatment to destroy harmful microorganisms and viruses.9. Feeder Tube - a device which holds Chlorine tablets in place in order to contact effluent.10. Ozone - an unstable, poisonous allotrope of oxygen, O3, which is formed naturally in the ozone layer from atmospheric oxygen by electric discharge or exposure to ultraviolet radiation, also produced in the lower atmosphere by the photochemical reaction of certain pollutants. It is a highly reactive oxidizing agent used to deodorize air, purify water, and treat industrial wastes.11. Pathogen - An agent that causes disease, especially living microorganisms such as bacteria, viruses, or fungus. 12. Swimming Pool Chlorine - Chlorine made from Trichlorisocyanuric acid instead of calcium hypochlorite. These tablets are not acceptable for use in On-site systems. They do not dissolve as quickly as wastewater grade tablets and do not treat effluent as required. Also, if not continually immersed in water, these tablets can be explosive due to the release of nitrogen chloride gas.13. Ultra-violet disinfection - disinfection device that uses ultra-violet light source to eliminate or destroy bacteria, viruses and other pathogenic organisms.14. Ultra-violet light - radiation lying in the ultra-violet range; wave lengths shorter than light but longer than X-rays 15 Miss. Code. R. 18-77-6.1.2
