Fluoride in Groundwater

Distribution Foreman CEU Training Course Description Water Distribution, Well Drillers, Pump Installers, and Water Treatment Operators. The target audience for this course is the person interested in working in a water treatment or distribution facility and wishing to maintain CEUs for certification license or to learn how to do the job safely and effectively, and/or to meet education needs for promotion. This course will cover the necessary water distribution information for the intermediate level of water distribution/water treatment operator. This course consists of 4 chapters of increasing subject/task difficulty. Because of the explanation of Water Distribution and Water Treatment Methods and related water fundamentals and a detailed understanding of pumps and motors, this is an excellent course that applies to both Water Treatment and Distribution Operators. This course also covers in detail: Disinfection, Chlorine, O3 and disinfection alternatives, and byproduct fundamentals. Water Quality, Tastes, and Odor Problems, MCL/EPA Rules, and a basic understanding of how the rules were created and implemented will be covered. This course will also cover advanced groundwater production and protection with problem-solving solutions.

Abstract: The purpose of the study to investigate the impact of the presence of iron and manganese found in  groundwater. The concentrations if both minerals as well as the location of the water source were identified along with its impact on water quality. Also, in this investigation a suitable method or  technique for the removal of both iron and manganese is selected taking into consideration the  local economic and environmental aspects. The removal will be accomplished by oxidizing both iron and manganese using aeration or using dissolved chemical oxidants converting them from  soluble to insoluble precipitates. Precipitates of iron and manganese hydroxides are formed and removed from water through settling and filtration units. In this research the concentrations of iron and manganese were analyzed from groundwater aquifers of a number of towns in the southern part of Libya. These concentrations were compared to the local and international drinking water standards set by the World Health Organization (WHO). Some water samples reported have shown a wide difference in iron and manganese concentration and selected for treatment in this  investigation. A complete treatment system has been designed to remove iron and manganese for  the groundwater at Brak city of Alafia since the iron and manganese exceeds the limits. The  oxidation of iron and manganese was done via aeration followed by flocculation and, settling,  filtration and finally disinfection. At Alafia city, iron and manganese concentrations were 3.1mg/L, and 0.32mg/L respectively as compared to the standards set by the World Health Organization,  2004 for concentrations of 0.3 mg /L, 0.1 mg /L respectively, This process is believed to be very  effective and economically feasible in the removal of both iron and manganese.
