Abstract

Wetlands are natural wet ecosystems with diverse and complex roles in nature and fundamentally wetlands are at least intermittently flooded with water depths that support the growth of emergent vegetation such as cattail, reeds, sedges, bulrushes, rushes, and grasess. The vegetation provides surfaces for the attachment of microbial films, aids on filtration and adsorption of wastewater constituents, transfer oxygen into the water column, and controls the growths of algae by restricting the penetration of sunlight. The extensive root systems serve as large surface areas for the development of microorganisms and enabling filtration as well as adsorption of sediment. Design of the system consisted of two wetland cells in series, namely the subsurface flow (SSF) and the free water surface (FWS) cells. The SSF had an effluent rate of 8 m3/day, surface area of 35,68 m2, bed width of 3,6 m, length of 10 m, depth of 0,6 m, cross sectional area of 2,16 m2, organic loading rate (OLR) of 179,37 kg BOD/ha-day, HLR of 0,2242 m3/m2-day, and residence time of 1 day. The FWS had a surface area of 19,71 m2, bed width of 2,5 m, length of 8 m, depth of 0,3 m, cross sectional area of 0,75 m2, OLR of 83,21 kg BOD/ha-day, HLR of 0,4059 m3/m2-day, and residence time of 1 day.

Abstract

The purpose of this experiment was to obtain glucose from corn-cob through enzymatic hydrolysis using cellulase from Aspergillus niger, and to study the effects of enzyme dose and particle size on the hydrolysis processes. The experiment was started with enzyme preparation from A. niger and cellulase examination. The experiment was then continued with corn-cob composition analysis. Hydrolysis with acid was conducted by immersing the corn-cob in FeTNa solutions. Cellulose hydrolyses using enzyme from A. niger at various particle sizes and enzyme doses were performed and compared. The best activities of cellulase was observed at a concentration 2.257 IU/mL with incubation time of 4 days. Conversion of cellulose to glucose was best (51.01%) at corn-cob particle size of 100 mesh and enzyme volume of 50 mL.

Abstract

The purpose of this study was to degrade food wastes to simple compounds. The experiments were conducted using a slurry aerobic bioreactor with a working volume of 25 L. The bioreactor was aerated with an air flow rate of 12 L/min and an organic loading rate of 2 g/L.day. Parameters determined during operations were total solids, COD, dissolved oxygen, pH, total nitrogen and total phosphorous. The results showed that during operation time of 90 days, the oxygen requirement for degradation of food waste was 0.35 g O2/g dry weight. The degradation of solid waste was 79.60% and the removal efficiency of total COD was 79.40%. Dissolution and mineralization of food wastes achieved maximum nitrogen concentration of 123.3 mg NH4-N/L and that of phosphorus of 32.2 mg PO4-P/L. It concluded that the aerobic bioreactor could decompose fresh food wastes during a time period of 90 days without intermittent removal of suspended solids in the system.

Abstract

The aims of this research were to study the ability of Phanerochaete chrysosporium biomass to adsorb metal ion of Cr(VI), to obtain equilibrium data concentrations and biosorption kinetics. P. chrysosporium was incubated in a sterilized liquid media of peptone 12.5 g/L and 50 g/L glucose at 35oC for 6 days. The obtained biomass culture was treated with NaOH 0.5 N, and then boiled for 15 minutes. A variety of biomass concentrations were mixed with 200 mg Cr(VI)/L in erlenmeyer flasks and vibrated by a shaker at 300 rpm during 0-200 minutes. Cr(VI) concentrations were measured using a spectrophotometer at 540 nm. The results showed that the maximum capacity of biosorption was approximately 5.13 mg/g. Estimation of biokinetic parameter, k1 was 0.015 minute-1 with a correlation coefficient of 0.91. It was concluded that the amount of P. chrysosporium biomass affected the equilibrium concentrations of Cr(VI) ions. The biosorption kinetics of Cr(VI) ion followed the equation of first order reaction.

Abstract

Distillery wastewater from ethanol fermentation has a high content of organic materials. Therefore, it can be used as raw materials for biogas production. The purpose of the experiment was to study the performance of Upflow Anaerobic Sludge Blanket (UASB) bioreactor to convert vinasse wastewater to biogas and other simple materials. A bioreactor was inoculated with 4 L sludge from a full-scale UASB bioreactor. The bioreactor was operated at a volume of 9 L. Vinasse was fed to the bottom of the bioreactor with a flow rate of 0.4 L/h using dosing pump. A variety of organic loading rates (OLR) applied were 5.49, 10.99, and 16.49 kg/m3.day respectively; and hydraulic retention time (HRT) of approximately 22 h. The results showed that the maximum COD removal was 61.59% and the maximum biogas volume was 4.59 L/day (3.28 L CH4/day) with OLR of 10.99 kg/m3.day. With OLR value of 5.49 kg/m3.day, a maximum CH4 content of 74.86%, CH4 yield of 0.11 m3 CH4/kg COD consumed, and a heating value of CH4 of 11,875 kcal/kg were achieved.
