Removal of Iron and Manganese from Groundwater Using Metakaolin
Usage of zeolite as adsorbent in water treatment has been well investigated and presented in many studies. Nevertheless, recent studies also suggest the potential of calcined clay or metakaolin in performing similar adsorbent function. This study aims to investigate metakaolin’s potential in groundwater treatment, mainly in the removal of iron and manganese. In the investigation, raw metakaolin (MK1) and calcinated metakaolin at 400 ℃ (MK2), 600 ℃ (MK3) and 1000 ℃ (MK4) were used as an adsorbent. The effect of dosage, speed and contact time were studied to determine an optimization. The highest removal obtained in the study was iron removal, which was 95.47%. MK4 was the best adsorbent among all adsorbents. The adsorption performance of MK1 was inconsistent in comparison to MK2 and MK3. However, MK1 adsorption ability was testified to be consistently below MK4. In the equilibrium data analysis, Freundlich isotherm model found to fit the adsorption data in this study better than Langmuir isotherm. Based on the removal rate established in the study, metakaolin is a potential adsorbent in the removal of heavy metals, specifically iron and manganese. The findings also indicated that all the physicochemical parameters measured except for pH were exceeding the values permissible level in the National Drinking Water Quality Standard.
