Abstract

ABSTRACTLeachate is one of the inevitable consequences of the practice of solid waste disposal in open dumping that can cause environmental problem, especially water pollution. The biological methods have been proved as an efficient alternative for the treatment. Designing the best operational system for leachate treatment would require the determination of the biological kinetics that are valid only for a certain practiced process. Two types of open dumping leachates, which were taken from drought and rainy season, were used to determine the kinetics, Yg, Ks and b. The acclimated activated sludge was used in three batch reactors with different initial MLVSS concentration (1700, 500 and 400 g/l for 1st, 2nd, and 3rd reactors). The parameters observed on this research were COD (Chemical Oxygen Demand), MLSS (Mixed Liquor Suspended Solids) and MLVSS (Mixed Liquor Volatile Suspended Solids). The research shown that  value ranges from 0.058 to 0.372 (dˉ1), Yg value ranges from 0.6166 to 0.9114 (mg MLVSS/mg COD), Ks value ranges from 353.4 to 3362.1 (mg/l), and b value ranges from 0.1248 to 0.132 (dˉ1), for the dissolved oxygen of 2.7-4.6 mg/l and pH value around 7-9. The parameters of bioreactor design were calculated based on the 3rd reactor kinetic values for the influent flow rate (Q) of 20 m3/d, the mean cell-residence time (c) of 10 days and the MLVSS concentration of 3200 mg/l, with COD and BOD5 of 10 000 mg/l and 3800 mg/l, and COD and BOD5 effluent of 50 mg/l and 38 mg/l. The result of bioreactor design were as follows: reactor volume of 171 m3, the sludge production of 54.6 kg/d, the oxygen requirement of 96.1 kg/d, the power requirements for blower of 5.1 kW, and the reactor dimension of 4x7.125x6 m for depth, length and wide.Key words : leachate, activated sludge, kinetics parameter

Abstract

ABSTRACTCastor oil may be dehydrated in such a way that the hydroxyl group, along with a neighboring hydrogen atom, is eliminated, leaving two double bonds. This new form known as dehydrated castor oil (DCO). In the manufacture of DCO, castor oil is subjected to catalytic dehydration. The choice of catalyst is very important in the catalytic dehydration process because the reaction and quality of the resulting product mainly depend on the catalyst. Sodium bisulfate and attapulgite (aluminum-magnesium-silicate) potential to be utilized as catalyst for dehydration of castor oil. The dehydration reaction kinetics of castor oil was investigated with sodium bisulfate–attapulgite mixture as catalyst. The rate of dehydration of castor oil was constructed from experimental data by considering the disappearance of hydroxyl groups. Reactions were carried out at 190, 200, and 210C, and kinetic model was determined for each case. The equilibrium conditions were investigated based on the decreasing of hydroxyl value during the dehydration process for each temperature. In the equilibrium conditions, hydroxyl value of 80.85, 70.81, and 51.59 were reached 150 minutes at 190 and 200C, and 120 minutes at 210C, respectively. The integral method was used to correlate the experimental data. The second order rate equation showed the best fit to the experimental data for all reaction temperature. The rate constant dehydration of castor oil at 190, 200, and 210C are 4,03 x 10-5 [(w%)-1(min)-1], 4,83 x 10-5 [(w%)-1(min)-1], 10,3 x 10-5 [(w%)-1(min)-1], respectively. The activation energy at that condition is 5,24 kcal/mole. Key words : Castor oil, dehydrated castor oil, kinetics
