Heavy Metal Waste

Development of the industry, especially the palm oil mill industry, it will have an impact with tangible evidence that makes the environment polluted. Heavy metals will be produced from the palm oil mill industry and will pollute the environment. Zn metal is one of the heavy metal waste produced from the mustard coconut factory industry. Zn heavy metal waste will be very dangerous if it exceeds a predetermined level and will have an impact on humans, animals and the environment. One effort to reduce heavy metals using the adsorption method. Adsorption has advantages over a variety of other methods. Adsorban that is used from materials found in nature and the resulting waste can be used as an adsorbent. The type and type of adsorbent greatly affect the pH adsorption level of the Zn metal solution.

A research has been conducated on using charcoal as a filter to control river water pollution with heavy metals from palm oil mill waste based on physical parameters in Kuantan Singingi district using SSA method. The process begin with taking sample from palm iol mill waste output, the the temperature and electrical conductivity of it is mesured. Heavy metal concentration (Zn) is mesured with Atomic Absorption (SSA). The highest electrical conductivity value before filtrasion was found in factory A sampel. The value is 8,87 x  10-4 Ωm-1with 0,241 mg/l Zn concetration. Electrical conductivity value decreased after filtration to 7,11 x 10-4 Ωm-1 with  0,216 mg/l mg/l Zn concetration. While the lowest electrical conductivity value before filtration was found in factory C sample. The value is 4,65 x 10-4 Ωm-1with 0,169 mg/l Zn consetration. Conductivity value decreased after filtration to 4,26 x 10-4 Ωm-1with 0,154 mg/l Zn contretation. These result explain that using charcoal as a filter for pollution control is uqite effective.

The study on the impact of palm oil mill processing activities on the environment of Bukit Mendi Palm Oil Mill was conducted by determining the distribution of six heavy metal concentrations Cadmium (Cd), Copper (Cu), Manganese (Mn), Lead (Pb), Iron (Fe) and Zinc (Zn) and the selected pollution indices. This study provided some information on the accumulation of heavy metals in the selected area and served to identify the potential sources contributing to these heavy metals. Soil samples were collected from eight sampling sites around the palm oil mill and analysed for the selected metals using ICP-OES. Three types of pollution indices were used to observe the pollution level of the area, namely Enrichment Factor (EF), potential ecological risk index (PERI), and Contamination Factor (CF) of heavy metal content. The average total concentration of the selected metals was found to increase in the order of Fe, Mn, Zn, Cd, Pb, and Cu. The metal Fe showed the highest metal content, followed by Mn at 1573.00 mg/kg and 154.00 mg/kg, respectively. The values of EF showed that the metal was unevenly distributed throughout the sampling areas, where heavy metal content ranged from minimal to extremely high enrichment. The potential ecological risk ranging from low to severe was observed in this study. The CF values revealed that the area was heavily contaminated with Cd and only slightly contaminated with Pb. The pollution indices determined in this study suggested that the study area was moderately contaminated with metals, and the metal Cd was found to be the only metal potentially posing an ecological risk to the area.Keywords: ICP-OES, palm oil mill, heavy metals, soil pollution, pollution indices

Packed bed column studies were carried out to evaluate the performance of naturalCeiba pentandra(L). Gaertn. (kapok) for the heavy metal removal from Palm Oil Mill Effluent (POME) under varying flow rate (5-10 ml/min) and packing density (0.04-0.08 g/cm3). A multilevel factorial design based on Packing density and flow rate of the influent was developed. Maximum metal reductions for Fe, Mn and Zn were 2.06 ppm, 0.081 ppm, and 0.064 ppm respectively obtained at 0.08 g/cm3packing density and 5 ml/min flow rate. The results suggest the suitability of raw kapok fiber for low-cost removal of heavy metals.

Sorption of heavy metals on solid matrices such as soils is one of the key processes which determine the fate of contaminants in the environment. Knowledge of adsorption behavior of heavy metals using biochar is essential for their application in soil remediation. Using the adsorption method, the possibility of using a wood biochar to detoxify Fluvisols contaminated with heavy metals (for example, copper) was studied. It is shown that the addition of biochar increases the metal adsorption capacity of soil. The results were analysed using the Langmuir and Freindlich isotherm equations. It was concluded that biocar can be applied to immobilize heavy metals in contaminated soils.
