Treatment Of Groundwater For the Removal of Iron and Manganese From Groundwater wells of southern of Libya
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.

Iron And Manganese Removal From Groundwater
Abstract:
Drinking water supplies are based on ground water resources all over the world. At some localities problems with higher concentrations of iron and manganese found in ground water. These higher concentration of these metals result in metallic taste of water, effect color and flavor of food and cause staining of different products like paper, cloths, and plastics. Therefore World Health Organization has approved the treatment of water if concentrations of iron and manganese are higher than 0.3mg/L and 0.1 mg/L. Several techniques have been applied to remove iron and manganese from groundwater. The issue of higher concentrations of iron and manganese in groundwater wells at Grindalsmoen in Elverum Municipality in the south eastern part of Norway has been investigated by a PHREEQC geochemical model. The aim of this investigation was to analyze the relationships between oxygen levels and precipitation rates of iron and manganese. For this purpose geochemical simulations were performed with PHREEQC model with radial and linear flow. Results proved that concentration of oxygen at the water works (at its corresponding partial pressure) is high enough to precipitate the level of iron and manganese found in groundwater. The concentration of oxygen in equilibrium air at our desired temperature of 6 degree centigrade was 12.3 mg/l calculated by PHREEQC. Geochemical simulations were performed by the one dimensional column flow and radial flow towards well. The phenomenon of sorption was also included in model to see the adsorption behavior of iron and manganese. Overall this geochemical study has provided satisfactory results.

Distribution Foreman
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.
