Abstract

Palm oil mill effluent is one of the by-products of palm oil producing which contains high organic matter, so it needs a treatment before discarded into the water. One of the treatment method that can be done is by utilizing the organic matter into a source of nutrition for the growth of microalgae Chlorella sp. This study is conducted to determine the ability of microalgae Chlorella sp. in removing COD of palm mill effluent and knowing the specific growth rate of cells Chlorella sp. during the allowance process. Chlorella sp. has a small size, smooth, low density and easily carried by the flow of wastewater, so the cells Chlorella sp. immobilized with calcium alginate to make the cells are more stable and protected from the pressure of wastewater. In this study, the continuous system is carried out by replacing wastewater with fresh wastewater at variations of the wastewater volume replacments 0, 25, 50, 75 (% v/v) at 24 hours contact time. The removing process is carried out for 7 days with irradiation on the light intensity 5000 ± 300 lux and the lighting period (L:D) 12:12. The stirring process uses an aerator with 3 L/minute aeration discharge. The results showed that the 25% wastewater volume replacement was able to put aside the best COD with removal efficiency 85.71% at the best removing process detention time 7 days. Keywords: Chlorella sp., Semicontinuous systems, Palm Oil Mill Effluent, COD, Contact Time.

Abstract

Greywater is a waste from kitchen, bathroom, and laundry activities that contains high organic matter. The organic matter contained in the wastewater is utilized by the microalgae Chlorella sp. as a source of nutrient and its reduce the pollutant in wastewater. This study aims to count the number cells of Chlorella sp. which grew in suspension and attached to the Kaldness 1 (K1) biocarrier media and the removal of COD in domestic wastewater using Sequencing Batch Biofilm Reactor (SBBR). The SBBR was operated on 4 cycles consisting of 30 minutes of filling time, 120 minutes of reaction, 45 minutes of decanting, and 120 minutes of stabilization time. This research was carried out with a working volume of 5 liters, 30% K1 kaldness media, and 25% suspended microalgae concentration with variations in stirring speed (40 , 60, and 80 rpm) and variation of settling time (30, 45 and 60 minutes). The best results showed a decrease in COD variations in stirring speed of 60 rpm and settling time of 60 minutes, COD removal efficiency was 78% from the initial COD concentration of 288 mg/L to 64 mg/L.Key Word : Sequencing Batch Biofilm Reactor (SBBR), Domestic Wastewater, Chlorella sp., Biocarrier Kaldness 1.

Abstract

Wastewater produced from palm oil industry could potentially cause pollution because it contains the value of COD and high organic matter that can effect the death of aquatic biota. Wastewater from the outlet Waste Treatment Unit PT. X is still above the quality standards set by the government. Therefore research on acute toxicity test of palm oil industry to determine the value of LC50 and to analyze the relationship of wastewater from the outlet Waste Treatment Unit PT. X towards the experimental animal. This research was done by renewal test method in 96 hours of observation by using Catfish (Pangasius sp.) as the test animals. LC50 value was calculated by probit method which utilized the catfish mortality and the parameters tested was DO, pH, temperature, COD,ammonia and nitrate. The characteristic value of wastewater of palm oil PT. X is COD 1426,8 mg/l, ammonia 0,9909 mg/l, nitrate 0,0075 mg/l, pH 8, DO 3 mg/l, and temperature 28°C which the parameter of COD passed the quality standar of the Environment Minister’s decision No. 51/MENLH/10/1995 about the Quality Standart of Waste Water for Palm Oil Industry. The result showed the value of LC50 is 9,878% and TUa (Toxicity Unit Area) of palm oil industrial wastewater is 10,22 showed that the wastewater of palm oil could make great acute toxicity.Keywords: catfish, palm oil wastewater,the value of LC50, renewal test.

Abstract

Energy consumption is increasing steadily with the population growth and industrial development. Therefore, a substitute should be found. Bioethanol has been pointed out as a solution for variety complex problems related to energy and environmental issues. One of material that has potential to be used as raw material for bioethanol is microalgae. Microalgae Chlorella pyrenoidosa can be lived in wastewater, such as in palm oil mill effluent. Chlorella pyrenoidosa has been considered to be aviable and renewable feedstock for bioethanol production because it high carbohydrates contain. Chlorella pyrenoidosa is hydrolyzed into glucose for further fermented into bioethanol. This research aimed to observe the best condition on fermentation process by concentration of yeast are 10%, 15%, 20% and 25%. Measurement of bioethanol concentration using refractometer. The analysis show the highest concentration of bioethanol was 0,28% using yeast 25%.Keywords : Chlorella pyrenoidosa, hydrolysis, fermentation, bioethanol

Abstract

Hotel wastewater contains pollutants such as COD if discharged directly the environment has a harmful effect on the environment. If not processed it will cause excessive growth of algae or aquatic plants (eutrophication). The study was conducted to determine the efficiency of waste treatment hotel in reducing the parameter of COD using the method Moving Bed Biofilm Reactor (MBBR) by utilizing Chorella sp. This research was carried out by growing biofilms on kaldness (K1) media and air injection by aerators with variations of air injection 3 L/minute ; 6 L/minute ;9 L/minute ; and control (without air injection) with processing time of 5 days. Based on the results of wastewater treatment research hotel with the MBBR method with air injection 6 L/minute, it was able to reduce the parameters of COD to below the quality standard. The highest cell density of Chorella sp. suspended and attached in a row that is 1,595 dan 1,587 (x107 cell/ml) with the density of the cell is able to reduce the COD parameter from concentration of 485,6 mg/L to 80 mg/L and efficiency of 83,53 %, so that hotel wastewater doesnot pollute the environment if it is discharged into water bodies.Keywords : COD, Kaldness (K1), Hotel Wastewater, MBBR, Chorella sp.
