    Acid mine drainage (AMD) formation is due to the sulfide minerals reaction either chemically or biologically when exposed to atmospheric conditions. The AMD formation often occurred in the region involved with anthropogenic activities, including mining, agricultural plantation, urban development and logging. Treatment of AMD is a challenging part of most mining operations around the world. Selection of method treatment is crucial depending on the area’s geological, mineralogical, topography and AMD characteristic. There are two types of method treatment; active and passive treatment method. In this study, passive treatment method was adopted; which is successive alkalinity producing system (SAPS). The study aims to analyze effect of variable parameters on iron (Fe) concentration and propose optimum operating condition for AMD treatment. Peat soil and limestone aggregate was used as treatment media in treatment tank. Synthetic AMD was formulated using sulphuric acid (H2SO4) and iron sulfate (FeSO4) to represent actual AMD. Once the synthetic AMD was introduced, water samples were collected and analyzed using UV–Vis test after 6 to 48 h’ retention time. Based on the analysis, the proposed methodology has successfully reduced more than 85% iron content only after 6 h of retention time. The maximum Fe removal percentage recorded was 95%, using the higher peat soil depth configuration. The statistical analysis results show that the optimum operating condition for SAPS with high Fe removal is using high peat soil depth. Experiments with higher peat soil depth provide satisfactory results in treating the high initial Fe concentration regardless of the retention time for the AMD treatment.

    Study had being conducted to investigate the chemical properties of Airborne Particulate Matter (APM) which present in the ambient air of Parit Buntar Town and Nibong Tebal Town. These towns are located in Northen Perak and in southern part of Seberai Perai, Penang respectively. Non-reactive carbon tape was attached onto an aluminium stub to collect APM. The stub was exposed to the air for 24 hours to collect APM which will be deposited naturally due to the gravity action. Stub containing APM was analyzed by Energy Dispersive X-ray (EOX) to obtain elemental components. Results obtained from the analysis have shown that carbon (organic carbon or! and elemental carbon), 0 , AI, Si and other species such as Ca, K, Fe and Mg are the common elements present in the A PM.

    Acid Mine Drainage (AMD) is an untreated outflow of acidic water from metal or coal mines. Improper treatment of the harmful effluent causes major environmental concern and remains as an unsolved problem for mining operators worldwide. The untreated AMD contains high concentration of several heavy metals despite low pH level. Iron (Fe) is most dominant element of heavy metal spotted in the AMD water and must be filtered and treated before being released to open water bodies. Current practises by the industries adopted two categories of AMD treatment methods, namely active and passive treatments. Passive treatment method was adopted into this study by using successive alkalinity producing system (SAPS) to reduce Fe concentration in the AMD. Strict regulations by mine operators to acquire on-site AMD, led to use of synthetic AMD. Peat soil was introduced as organic substrate treatment media, as compared to common materials used such as mushroom spent, wood shaving and animal manure. In this research the peat soil was characterized and its effectiveness to filter the Fe content was assessed using laboratory scale studies. Prior to the test, the natural peat soil was analyzed via Scanning Electron Microscopy (SEM) analysis, Energy Dispersive X-Ray (EDX) analysis and carbon-hydrogen-nitrogen-sulphur (CHNS) element analysis. After going through laboratory tests, the peat soil residues were assessed through SEM-EDX analysis to determine the trapped Fe content. The natural peat soil does not contain any Fe substance. However, the analyzed peat soil residues showed that, approximately one to four percent of the Fe were found in the peat soil residues. The use of the peat soil for the AMD treatment in SAPS method is applicable and can be used as alternative organic substrate for treatment media.
