| description | From all the water quality problems of groundwater sources, the most common type of water quality problem is the excessive presence of iron and manganese. The quality of groundwater could be improved through aeration process by increasing the air entrainment/mass transfer of oxygen using ejector and filtration process by using different sizes of filter media. An investigation of the ejector was carried out to study the aeration efficiency by using 2 different types of ejector and removal efficiency of iron and manganese by using different sizes of filter media. Ejector 1 was taken from the previous study, meanwhile ejector 2 was designed according to the new parameter investigated. The groundwater samples were obtained from Rumah Anak Yatim Nur Kasih, Taiping. A laboratory model of ejector was used for aeration process and limestone roughing filter was used for the filtration process. Using groundwater, ejector 1 was able to achieve the higher aeration efficiency (E20=0.6005) compared to ejector 2 (E20=0.5841). It was found that the highest efficiency removal for iron was 53.4% (residual concentration of 1.23 mg/L) using ejector 1 and 89.7% (residual concentration of 0.03 mg/L) using ejector 2. For manganese, the highest efficiency removal was 50% (residual concentration of 0.8 mg/L) using ejector 1, meanwhile for ejector 2 the highest was 79.3% (residual concentration of 1.23 mg/L). Although, the residual concentration of iron and manganese were still higher than drinking water standard of 0.3 mg/L and 0.1 mg/L respectively, the results will provide modifications to the design of the ejector and increase its potential to be used as a treatment method for groundwater at Rumah Anak Yatim Nur Kasih. |
