Abstract Increased demand for drinking water has led to increased groundwateruse, which has become the key source of supply for many regions of the world, Groundwater resources are one of the non-conventional water resources, which are characterized by their geographical spread in the Arab Republic of Egypt. This research presented a solution for treatment groundwater by using Electro-coagulation (EC) technique to remove the different element such as heavy metals (iron, manganese), and reduce the different parameters such as Turbidity, Total Alkalinity, Conductivity, pH, TDS, Fluorides, Magnesium, Sulfate )SO4(, Magnesium carbonate (MgCo3). The influence of various operating parameters of EC, such as retention time, current intensity, and distance between electrodes were explored for effective treatment of ground water, where Aluminum sheet was used as the electrode material, distance between electrodes was varied from 0.005 m to 0.02 m and the current intensity was varied from 1.5 to 4.5 ampere with retention time from 20 to 60 min. When the current intensity was (4.5 ampere) with retention time (30 min) and the distance between the electrodes was (0.5 cm) the best result of removing iron, Turbidity and Fluorides is obtained, and the percentage of reduce was 89.9 %, 92.06 % and 90% respectively. When the current intensity was (3.5 ampere) with retention time (45 min) and the distance between the electrodes was (1 cm) the best result of removing mmanganese is obtained, and the percentage of reduce was 75.42 %. When the current intensity was (3 ampere) with retention time (60 min) and the distance between the electrodes was (0.5 cm) the best result of removing total alkalinity, conductivity, TDS, Fluorides, magnesium, sulfate and MgCo3 is obtained, and the percentage of reduce was 49.85 %, 23.09 %, 23.09 %, 90 %, 43.39 %, 26.6 % and 43.71 % respectively. |
