Abstract

High production of palm oil contributes to the high waste water produced. This is because the high water consumption during the production process is about 5 m3 per processing of one ton of fruit palm. The palm oil mill is an important concern because it contains organic materials, tannin compounds and high soluble solids. So it takes an environmentally friendly processing to eliminate pollutants so as not to cause environmental damage. Therefore, in this research, the effluent treatment using Chlorella sp. which is immobilized to exclude TSS parameters. Cell immobilization process is done by using calcium alginate as a polymer to form beads. In order to obtain stable and high efficiency beads, variations of Na-alginate concentration (4%, 6%, 8%) and contact time (1, 3, 5, 7 days) are obtained. Based on the result of the research, it is found that the most stable bead is made of 8% Na-alginate with a removal efficiency of 35.3-76% within seven days.Keywords: Chlorella sp, COD, Contact Time, Na-alginate, Palm Oil Mill Effluent, Total Nitrogen, Total Suspended Solid.

Abstract

Bengkalis has a characteristic red soil water that people use other alternatives such as the use of rain water as drinking water, seawater however Bengkalis potentially be processed into clean water. One alternative treatment of sea water into fresh water is to use ion exchange method. This study uses an ion exchange method which utilizes clay Kulim. As well as ion exchange column used 2 inch diameter and a height of 1.2 meters. The medium used is activated clay and sea water Bengkalis Island. Variation used is acid solution HCl, HNO3, and H2SO4 with each solution concentration 2M and clay without activation as a control. Used detention time is 180 minutes, while the clay size -10+15 mesh. From the results, the highest efficiency in H2SO4 activated clay with an efficiency of 95.2% Pb concentration of 1.201 mg/L to 0.058 mg/L. When in comparison with clean water quality standard Pb concentration in sea water not meet quality standards. Then calculated the value of the clay CEC and CEC highest value obtained is 124.16 meq/g on activated clay H2SO4 These results indicate that the ion exchange method using activated clays are capable of removing Pb and Ca concentrations in seawater.Keywords: Acid Solution, Ion Exchange, Kulim Activated Clay Soil, Sea Water of Bengkalis

Abstract

Develpoment of a dynamic world energy consumption within the limitation of fossil energy reserve as well as the awareness on the environmental conservation evoke the increase of interest on a renewable energy. Chlorella pyrenoidosa is commonly recognized as in interesting species for bioethanol production due to its the carbohydrate content. Palm Oil Mill Effluent (POME) is a potential medium for microalgae to growth because it contains high nutrient sources. This research aimed to study the effect of POME concentration and light intensity to carbohydrate produced of microalgae C. pyrenoidosa. Microalgae cultivated in POME : Medium Dahril Solution (0:100; 25:75; 50:50; 75:25; 100:0) with light intensity (3000, 4000 and 5000 lux). The result showed the highest carbohydrate concentration was 289,69 mg/L at cultivation condition of POME : Medium Dahril Solution 50:50 with the light intensity 3000 lux.Keywords: Chlorella pyrenoidosa, Palm Oil Mill Effluent (POME), Dahril Solution Medium, Carbohydrates
