Item Evaluation of mixed-oxidants against sodium hypochlorite for the disinfection and removal of biofilms from distribution systems(Montana State University - Bozeman, College of Engineering, 1997) Crayton, Cynthia Lynn; Chairperson, Graduate Committee: Anne CamperProblem Statement: As drinking water regulations are applied to smaller utilities, an area of emerging concern for the water industry is the installation of disinfection systems to meet the newly imposed standards. Since traditional disinfection technologies are usually beyond the safety, economic, and/or site restraint considerations for small systems, an alternative is required. The mixed-oxidants disinfection system (MIOX) appears to provide a reasonable alternative for small distribution systems as a safe, reliable, and cost effective technology that is easy to operate and is readily compatible with other treatment systems. The goal of this five-phase study was to evaluate the potential of the MIOX disinfectant (produced on-site using feedstocks of ordinary salt, water, and twelve volt electricity) against free chlorine for biocidal efficacy, biofilm/biofouling removal, biofilm regrowth potential, relative corrosion potential, and cost effectiveness. Although mixed-oxidants have been proven effective in potable water disinfection, biofilm removal is a new application for this alternative disinfection technology.Item Predicting soil water distribution using topographic models within four Montana farm fields(Montana State University - Bozeman, College of Agriculture, 2002) Kozar, Brian JohnItem Factors influencing biofilm growth in drinking water distribution systems(Montana State University - Bozeman, College of Engineering, 1995) Camper, Anne KosteczkoItem Application of the biofilm coupon as a direct measure of the in situ growth potential of water(Montana State University - Bozeman, College of Agriculture, 1995) Bakich, Shannon GaylordItem Comparison of models for bacterial regrowth in water distribution systems(Montana State University - Bozeman, College of Engineering, 1995) Nichols, Naomi Ruth WrightItem Application of the biofilm coupon to bacterial regrowth potential(Montana State University - Bozeman, College of Engineering, 1993) Xu, Xiaoming
