Abstract

The project covers a study on the topic entitled "Removal of Iron from Groundwater by Filtration through Carbonaceous Shale". Generally speaking, Iron is commonly present in groundwater worldwide. The presence of iron in groundwater is not harmful to human health, however it is undesirable because of the associated aesthetic and operational problem, namely: bad taste, discoloration, stains on laundry and plumbing system and after-growth in the distribution system. Iron present in soluble ferrous form in groundwater oxidizes into insoluble ferric iron when exposed to the atmosphere. Iron removal from groundwater is, therefore, a major concern for water supply companies using groundwater. The objective of this study is to determine the effectiveness of carbonaceous shale in removing iron from groundwater by adsorption-oxidation mechanism and also the backwashing system for the filter. The scope of work consists of literature review, experimental design, laboratory set up, experiments and results analysis. The methods and procedures to achieve the objectives involve analyses of chemical parameters of groundwater used in the experiments including the properties of carbonaceous shale and also filtration performance of carbonaceous shale. Laboratoryscale colnnm experiments were conducted using 31 mm diameter acrylic column pipes with 1.0 m depth of 1.0 mm mean size and having 70 em depth of filter media. The filtration performance of the carbonaceous shale was compare with the sand that works like a 'benchmark' since it is been widely used in the conventional method for iron removal. Both filtration media that been used act as adsorbent of ferrous iron in filtration column. Results from the experiment shows that the concentration of total iron in the groundwater used in the experiment is 2.36 mg/L Fe and that the performance of carbonaceous shale filter is better than sand filter in the iron removal. Iron concentration in the effluent of carbonaceous shale filter is below standard for drinking water which is 0.3 mg/L.
