Abstract

This research aims to study the effect of liquid flow rate and bed height on mass transfer coefficient in theadsorption of detergent in water using activated carbon adsorbent in the fluidized bed column. Theexperiment was preceded by an orifice meter calibration and manufacture of detergent solution in water atvarious concentrations. Detergent solution was then fed into the tank inffluen on fluidized bed column andflowed into the column at various flow rates and higt of bed. Effluent from each variation of measuredconcentrations and calculated % detergent absorbed and mass transfer coefficient.The results showed that increasing the flow rate increases the amount of detergent liquid is absorbed andthe mass transfer coefficient. For high-bed 10, 20 and 30 cm, the higher the bed the higher the amount ofdetergent to be absorbed and the mass transfer coefficient. % Detergent which absorbed the highestachieved at influent concentrations of MBAS concentration of 0.054 mg / lt, and 30 cm bed height that isequal to 25.9%. The the highest mass transfer coefficient is 9,457.10-6cm / dt2 on influent concentrationMBAS concentration of 0.054 mg / l and 30 cm bed height.Key word: detergent, activated carbon, % detergent adsorbed, fluidization, mass transfer coeffisien

Abstract

The baffle influence to the degree of liquid mixing in the plate and the pressure drop on the plate has beenstudied in this research. The operational pressure in this research is limited in the atmospheric pressure .Thedistillation column that used in the research has 0.2m diameter and 1.4 m height with the distance betweentrays is 0.4 m. The research was carried out by to flows water into the column with the flow rate of water are105 l/h, 149 l/h, 189 l/h and to flows air into the lower of the column with superficial speed from 0 to 0.3 m/s.After steady state is required the dry plate pressure and the pressure drop because the difference between theheight of clear liquid and the height of foam is measured. The mixing degree is determined by stimulusresponse method, i.e flows air into the system, then give a tracer (i.e. NaCl saturated 20 CC) as a stimulatorthat injected into the fuild to the basin. This experiment will give the data off the concentrations and the time.The conclusion of this research is the pressure drop by dry plate can provide the correlation hD = 8.34926( )( ) Lh GgUρρ22. The value of residual pressure drop at the column of sieve plate without baffle and with use abaffle in this study almost constant, i.e. 1-2 mm H2O. The relation among the Peclet number, the F factor andthe flow rate of water can expresse in empirical equation are : for without baffle Pe = 0.3837 F0.9254 Q-0.05229;Baffle V, Pe = 0.00005306 F-2.341 Q-1.005; vertical Baffle Pe = 0.004989 F-1.775 Q-0.4848. The presentation of thedifference of the clear liquid’s height in the condition without use a baffle are 86,88% for the V baffle,53,55% for the vertical baffle (105 l/h); 73,5% for V baffle, 50,64% for the vertical baffle (149 l/h); 84,34 forV baffle, 65,58% for vertical baffle (189 l/h). The value of EMV / EOG for the experiment without use a baffle isgreater than the value of EMV / EOG fot the experiment use a baffle.

Abstract

The existence of Biodiesel as an alternative fuel from year to year has decreased quantity and will become lessand less because of rising demand. One source of biodiesel raw materials are seeds Avocadot.Seeds Avocadois still not utilized for other products, and avocado seeds contain fatty acid methyl esters of 71.715% asmaterial for biodiesel. The aim of this research is to make biodiesel from avocado seed oil so it can be used asalternative diesel fuels and also take advantage of avocado seed in order to have a high value in order to beprocessed into biodiesel. Operating conditions used was 10 ml volume of oil, transesterification temperature ±60 ° C, NaOH to oil weight ratio of 1% and stirring speed 600rpm. Also, studies conducted on the oil to methanolmole ratio 1:4, 1:6, 1:8, 1:10, 1:12 and with a variation of 5, 20, 35, 50 and 65 minutes. Peneliatianresults show that biodiesel meets the standard avocado seed oil as an alternative fuel in Indonesia because ithas a value of flash point between 130 ° C to 240 ° C and has a pour point value between -2 ° C to 9 ° C.Keywords: Seeds of avocado, transesterification, biodiesel.

Abstract

The combination of submerged membrane bioreactor (BRMt) and activated sludge is onealternative that can provide a solution. The purpose of this study was to determine the effect oforganic load on the performance of the combination of activated sludge and membranesubmerged, know the effect of microorganism concentration on the performance of thecombination of activated sludge and membrane submerged. Membrane bioreactor Awash (BRMt)used has concentration of biomass to be used is 15,000 mg / L, 20,000 mg / L and 25,000 mg / L,and COD concentration of MSG wastewater used was 10,000 mg / L and 15,000 mg / L. CODload successfully diremove average for each variation of the COD load of up to 98%. Inwastewater treatment using membrane processes, fouling is one of the obstacles that can interferewith the performance of submerged membrane bioreactor, so that by the backflushing andbackwash is to help improve the performance of membrane separation process in the processing ofthe waste. This is indicated by the analysis results that meet the standard of quality standardsbased on the Liquid Waste Kep. Gub No.45 of 2002.Keywords: wastewater, waste MSG, submerged m

This research aim to know the influence of stirring process to the capability of Phanaerochaete chrysosporiumto absorb heavy metal ions of Pb (II) in electroplating waste water. The methods of this researchstarting by developing and treatment of Phanaerochaete chrysosporium and then this biomass wascontacted with waste water that contain of Pb (II)in the stirring variable is 50, 100, 150, 200, 250 rpm andin the biomass consentration is 1,2 and 3 (mg/lt). After contacted 150 minute the result has analyzed byAAS. From the analyzed the metal ion of Pb(II) was known and then the analysis of data was done bycomparing the process before contacted and after contacted. From this research get that the optimimprocess is in 200 rpm, the number of adsorption metal ion of Pb(II) was increasing until 200 rpm, and inthis condition the optimum adsorption reach 66,79%.Keyword : Biosorption, stirring, waste water electroplating.
