Abstract

Remazol Golden Yellow 6 is a vinyl sulfone reactive dye with an azo-based chromophore, which produces a coloured wastewater that is difficult to treat by biological treatment. Physical adsorption of coloured wastewaters with activated carbon although effective is economically expensive. It is therefore necessary to find effective and economic alternatives for absorbant, such as microorganisms. The biosorption capacity of a mixed culture of dead fungi biomass (Aspergillus sp., Penicillium sp., and Saccharomyces sp.) for Remazol Golden Yellow 6 was examined as a function of initial pH and initial dye concentration. The results were compared to the adsorption capacity of a commercial activated carbon. Optimum initial biosorption pH was determined as 1. The percent dye removal of 0.5 g biomass with initial dye concentrations of 60 mg/l, 80 mg/l and 100 mg/l were 90.3%, 93.6% and 97.6% respectively with equilibrium established within 75, 125 and 150 minutes. In comparison, dye removal with granular activated carbon for the same dye concentrations were respectively 32.1%, 36.4% and 37.8 % with equilibrium time at 275, 400 and 475 minutes.

Abstract

A number of research activities have been carried out on the utilization of various kinds of solid wastes, namely rice husk ash, coal fly ash, residual cane ash, aluminium smelting residue, palm oil residual ash, and used tyre powder, as mixing components for road hardening pavement. Results of these research works were compiled in order to compare the strengths and effectiveness as road pavement mixing components. The methods for implementing the experiments and mixing processes were following the Indonesian National Standards (SNI) and the British Standards (BS) 594. This research showed that the mixtures of rice husk ash and coal fly ash, residual cane ash and cement, and aluminium smelting waste could be utilized for subgrade mixture components. These mixtures could increase the California Beating Ratio (CBR) value up to 25 times and the soil strength up to 6 times. The coal flyash, however, decreased the Plasticity Index (PI) value of about 8%. The CBR value of original subgrade soil of 1% was increased up to 14,78% using 3% of residual cane ash and PC type I using 4 day curing time. Using the residual cane ash of 6%, the initial PI value of 57,29% decreased to 32,05%. The PI value of aluminium smelting waste decreased from 43,36% to 29%. The initial CBR value of 2,73% was increased to 12,67% at 10% concentration within 7 days of dry condition. The coal fly ash met the specification as filler, so that it could be also utilized as Asphalt Treated Base (ATB) filler, as shown by the results of Marshall. The steel blust furnace crust could be used as coarse aggregate in hot mix blend, because it met the requirement as coarse agreggate, as proved by the Marshall test. The rice husk ash, coal fly ash, and palm oil residual ash could be used as filler of Hot Rolled Sheet (HRS), because they meet the specification after being mixed with another material. The Marshall test showed that stability, flow and film thickness also met the specification. The tyre powder met the criteria as an additive, and when mixed with another forming material also met the stability specification.

Abstract

The effect of CO2 to the environment can be reduced by converting the gas into valuable product. One of the alternative ways to make use of CO2 is by hydrogenation into methanol by catalyst. Research on hydrogenation of CO2 into methanol over natural zeolite, synthesized zeolite ZSM-5 and synthesized Cu/ZnO/Al2O3 catalysts had been done. The synthesized Cu/ZnO/Al2O3 catalyst was prepared by impregnation method, while the synthesized ZSM-5 was prepared by gel permeation method. Components of the catalyst were characterized by XRD method. Catalyst activity was examined by reacting hydrogen, carbon dioxide and nitrogen with the ratio of 6 : 3 : 1. The research was conducted at temperature of 300-500oC, with the reaction time of 2 h and the catalyst loading of 1 g with the variation of catalyst used, natural zeolite, synthesized ZSM-5 and synthesized Cu/ZnO/Al2O3. The results of catalyst characterization showed that almost all of the characteristic peaks of natural zeolite were alumina and silica and component of Cu/ZnO/Al2O3 were Cu, CuO, ZnO, and Al2O3. The crystallinity of ZSM-5 was low. Results of hydrogenation reaction showed that the highest CO2 conversion, methanol selectivity and methanol yield were 92%, 68% and 65%, respectively, obtained from the reaction over natural zeolite at reaction temperature of 500oC. Natural zeolite showed higher activity than synthesized ZSM-5 and Cu/ZnO/Al2O3.

Abstract

In a conventional wastewater treatment, all waste streams are collected in a sump pond and directed to the designated wastewater treatment unit. Actually, a wastewater stream is not necessarily required to be treated in specific process when its quality and quantity as its concentration and flow rate are already low. The wastewater can directly bypass to other unit process. A method, which was called Water Pinch Analysis to determine the minimum flow rate, was applied in this investigation. Initially a target of minimum flow rate was made including composite curve. Afterward, a pinch point was located and its tangent to the curve was drawn to get maximum concentration of the waste entering the wastewater treatment unit. The result showed that for multi contaminant and one treatment unit, a minimum flow rate of 44.14 ton per hour was found or a reduction of 5.5% from its maximum flow rate of 52 tons per hour. An output concentration of 66.08 mg/L at the wastewater treatment was obtained, which is above the tolerance limit. Multi contaminant and multi treatment unit showed a flow rate reduction of 51,6% of Unit Treatment I and of 23,3% of Unit Treatment II. The eflluent concentrations were of 36 mg/L COD and 13,86 mg/L ammonia. This results were below the industrial wastewater standards.

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

PT ECCO Tannery Indonesia as one of leading tannery industry has a high waste disposal potential in its daily operation. For such thing, it is necessary for the management to have an appropriate environmental management such as waste reduction. This research tried to address this problem with Green Productivity (GP) approach, so that efforts in waste reduction could provide improvement of environmental performance and productivity. The waste reduction alternatives was further formulated, and chosen to be implemented according to financial analysis and alternative contribution estimation either to the productivity level or to the EPI index level. Results of this research were expected to provide solution of the high waste volume problem, which had to be sent to PT Prasadha Pamunah Limbah Industri (PPLI) Bogor. The waste reduction was on the decreasing sludge and fleshy waste quantity by using sludge drying machine with a capacity of 15 tonne/day, which could dry the waste until 90% dry solid. This alternative contributed the productivity enhancement up to 0.91% and improved the environmental performance through waste volume reduction to be disposed of to PPLI Bogor of about 66.9%.

Abstract

At the present time, water scarcity in Bandung Basin has reached its critical point, marked with springs that stop discharging and lowering water table. The same condition can be seen on river water that heavily exposed by industrial waste along the river. Through environmental isotopes (2H, 18O and 14C) approach, the condition of deep and shallow groundwater wells alongside the river can be known. This research was conducted by taking some samples of shallow groundwater, deep groundwater and river water (Citarum, Cikapundung, Cikeruh and Citarik). The amount of water sample needed for 2H and 18O isotopes analysis was 20 ml, whereas for 14C isotope analysis, 60 liters of water sample needed to extract into BaCl­3 precipitation. Based on isotopes 2H, 18O and graphic 2H vs 18O data show that there are three of resident groundwater (shallow groundwater) which its groundwater have been mixing by river water. Whereas the result of isotope 14C, does not show inter relation, either by shallow groundwater or river water. From iso-age contour, it could be concluded that the dynamics pattern of deep groundwater show movement derived from north and south mountains to north-west direction (Cimahi and Leuwigajah). These locations are industrial area with very high groundwater exploitation.

Abstract

The wastewater from the washing unit of silverwork industries may contain toxic substances, such as lead, copper, silver, nickel, and mercury. The waste water is generally discharged to a nearby ditch or canal without any treatment. The waste water might cause a harmful effect to the aquatic organisms in the canal. This research was aimed to determine the effect of silver waste water to the microanatomy structure of the hepatopancreas of nila fish (Oreochromis niloticus Trewavas), and to measure the concentration of the waste water which caused the effect. The method used in this research consisted of acclimation of test animals, toxicity tests (orientation test, preceeding test, actual test) for determining the LC50-96 hours. Waste concentration levels of 0; 0,06 %; 0,07 %; 0,07 %; 0,08 %; and 0,09 % were used during this research. The experiment used 25 nila fishes which were divided into five groups. The next steps was preparing the hepatopancreas microanatomy using paraffin method. The cells were dyed with hematoxylin-eosin. The cell damage was analyzed qualitatively and quantitatively. The results of hepatopancreas microanatomy observation showed that the increase of nila fish hepatopancreas cell damage was proportional to the increase of silver wastewater concentration. The damage was shown as the occurence of cloudy swelling, hydrophic degeneration, fatty degeneration, and necrosis. Results of this research also showed that the waste water of the silverwork industry contained lead, copper, silver, nickel, and mercury, which exceeded the waste water quality standards.
