• Suitable for home use. • Able to improve taste and odor and removes chlorine. Limitations: • Relatively expensive O&M cost for regeneration. • Effectiveness is based on contaminant type, concentration, rate of water usage, and type of carbon used. • Requires careful monitoring when nearing breakthrough times. 7.1.12 Ultraviolet Disinfection Ultraviolet (UV) radiation disinfection is a popular form of primary disinfection because of its ease of use, no need of chemicals, and no formation of disinfection byproduct (DBP). Water is pumped through a UV reactor, which is equipped with an array of UV lamps providing disinfection dosages of 30–50 megajoules per square centimeter. As pathogens path through the reactor, they are inactivated. They are exposed to the UV light for a predetermined period of time, depending on the desired level of disinfection. UV reactors typically are closed channel for potable water treatment and are installed in open channel for wastewater treatment. There are several types of UV lamps, with low pressure- high output and medium pressure mercury vapor lamps being the most commonly used (Reclamation 2003). The lamps are housed inside of quartz lamp sleeves in the reactor to protect the lamp from breaking. The mechanism of UV disinfection is inactivation through UV damage of the microorganism’s deoxyribonucleic acid (DNA) and/or ribonucleic acid (RNA). Removal of suspended solids from the feedwater to UV is important to avoid shielding of microorganisms from the UV by suspended solids. This phenomenon is called “shadow effect.” UV disinfection does not provide a disinfectant residual. Therefore, addition of chlorine or chloramine as a secondary disinfectant might be required (Reclamation 2003). Disinfection is typically the last treatment step in most water treatment facilities, most suspended solids and/or dissolved ions, if any, should have been removed prior to disinfection. No waste is generated in UV disinfection. UV equipment including lamps must be properly checked to ensure they are working according to technical specifications. The lamps age with time and require periodic replacement. A cleaning system also must be installed on the lamp sleeves, because the sleeve itself reacts with compounds in water and would decrease the UV transmittance if they are not cleaned (Reclamation 2003). This disinfection has a high capital cost; with the USEPA estimated cost as $0.13 per gpd. 80PDF Image | Oil and Gas Produced Water Management
