Abstract

Carbohydrate content in microalgae can be used as raw material for producing biofuels. Microalgae need nutrients such as carbon and nitrogen also light for their growth. Nutrient source can be obtained from wastewater, such like hotel wastewater. The objective of this study was to determine the best condition for Chlorella sp producing high carbohydrate content by varying the C:N ratio 100:7, 100:13, 100:32 and the light wavelength using a white light color (380-750 nm), blue (450-495 nm), green (495-570 nm), and red (620-750 nm). The experiment was conducted at room temperature under 2000 lux illumination for 15 days. The results showed that Chlorella sp produced the highest carbohydrate content (45,77 mg/l) under C:N ratio 100:7. Moreover, when algae was cultivated under different light wavelength showed that Chlorella sp has grown better and produced more carbohydrate content (48,39 mg/l) under blue light (450-495 nm) when compared to the other types of light. Keywords: Chlorella sp, carbohydrate, C:N ratio, light wavelength

Abstract

The coastal area are poor raw water eligible to be used as a standard raw water based on PERMENKES No. 492/210 and PP No. 82/2001. This area typically used brackish water daily needs. Due to the presence of sea water intrussion in to wells. The brackish water are not suitable to be use continue. It therefore reguirestreatment to get suitable water. Pre-treatment of brackish water with contrarch as coagulant and filtration membrane as alternative technology to be developed in water treatment. This research aims to be knowing the influence of coagulant dose variation, the transmembrane flux and rejction against of salinity, turbidity,COD, TSS, and pH. This result are showing the best reduction of pre-treatment process in 50 ppm therefore efectivity each other are salinity 23,61%, turbidity 43,64%, COD 83,58%, TSS 98,03%, and pH 12,05%. The filtration with membrane each parameter are salinity 89,09%, turbidity 88,94%, COD 58%, TSS 85,71 and pH 27,10%.

Abstract

Palm Oil Mill Effluent (POME) is wastewater that has high organic mattercontent. The treatment process of Palm Oil Mill Effluent (POME) generally with the open pond system can be one of the contributors of greenhouse gases in the form of CO2 and CH4 gases. To prevent the release of greenhouse gases, microalgae are used by using POME which contains organic ingredients as a nutrition source for microalgae cultivation media to produce raw materials for biofuel (in the form of lipids and carbohydrates) that can be used to overcome the energy crisis. In this study, a microalgae-bacteria consortium of POME wascultivated in POME medium with a variation of injection of CO2 gas flow with variations (0,3; 0,5; 0,7) l/minute. The cultivation process was carried out for 13 days with radiation using sunlight. The results showed that at a flow rate of 0.5 l /min the lipid content was 45.21% of dry weight with μ = 0.850 / day. Theefficiency of removal of organic matter in the form of COD and total nitrogen is 87,36% and 69.92%.Keywords: Consortium, Microalgae, Indigenous, CO2 , Flow rate, Injection , Lipid, COD, Nitrogen total, Palm Oil Mill Effluent (POME)

Abstract

Wastewater from the textile industry has adverse effects on the environment if disposed of into the waters without any processing. Naphtol is one of the sources of pollutant wastewater coloring batik. Electrocoagulation is one of the alternative method of processing wastewater textiles. This research aims to know the efficiency decreased levels of COD and TSS contained in wastewater through the process electrocoagulation. Research carried out in batch by using aluminium as electrodes that size 17cm by 17cm x 3cm. The size of the reactor electrocoagulation is 30cm x 25cm x 25cm, 1 cm electrode spacing and waste from Volume 10 L. The voltage used was 10, 15, and 20 volts and then sample taken on 15, 30 and 45 minutes while electrodes from the electricity. The analysis showed a decrease in concentration on the parameters of the tested where the span of the efficiency of the allowance for a maximum range of the COD (80-00, 98, 20 %) and TSS (90, 83 % - 95, 83 %). This condition occurs at the time of tension 20 volts in 45 minutes. Based on the Anova to use SPSS.16, found that the voltage and time factor affecting the decrease in the concentration of 94.8% COD and TSS 93.1%. The rest is affected by unknown factors.Keywords: Electrocoagulation, wastewater batik, voltage, contact time, COD

Abstract

Peat water is surface water has a special characteristic, which is lightly browned, pH acidic and contains high organic and do not meet the quality standards of clean water that is PERMENKES No. 416/Menkes /Per/IX/ 1990 and Government Regulation No. 82 of 2001. One of the processing methods are widely applied in water treatment peat ie coagulation-flocculation. The use of natural coagulants such as tamarind seeds can be used as a substitute for synthetic coagulant. The aim of this study was to determine the influence of the mass and the particle size of tamarind seeds as coagulant for organic matter and COD, variations in the mass of peat water with tamarind seeds of 0.0025, 0.005, 0.0075, 0.01 and 0.0125 g / m3 and variations in particle size of 100, 170 and 200 mesh. Rapid stirring speed of 100 rpm for 4 minutes and stirring slow 40 rpm for 12 minutes. The results showed maximum efficiency on a mass of 2.5 g with 200 mesh tamarind seeds can decrease up to organic matter 76%, and COD 90%,. ANOVA test with SPSS shows that the mass of tamarind seeds and tamarind seeds particle size influence on organic matter and COD so that tamarind seeds can be used as a natural biokoagulan.  Keywords: Water Peat, Tamarind Seed, Coagulation Flocculation

Abstract

Organic matter in peat water can react with chlorine during the chlorinationprocess that cause the formation of trihalomethans (THMs) which can cause acancer because it’s carcinogenic. Organic matter also hard to be removed bytraditional coagulation (one-stage) due to its hydrophobic and hydrophilicfractions that requiring another alternative treatment like two-stage coagulationby using clay as a coagulant. Research using a jar test by varying the mass ofcoagulant that is 1, 2, 3, 4, 5 and 6 gr. In two-stage process, coagulant also splitequally for first and second coagulation with variations 1/3:2/3, 1/2:1/2 and2/3:1/3. The result showed that the highest efficiency for two-stage coagulationcan achieved 94,45% at addition of 5 gr of coagulant with 2/3:1/3 varian ofcoagulant split and already met the standard. Then the characterization offunctional bunch of organic matter doing by FTIR spectra and the result showedthat the functional bunch of hydrophobic like C-O from esthers, ethers andphenols bunch and C-C from aromatic bond also hydrophilic bunch like O-Halcohol can not be detected after two-stage coagulation process.Keywords : Peat water, organic matter, clay and two-stage coagulation

Abstract

In general, in the water treatment process, the process of separating water from solids occurs in the form of flocculant particles or sedimentation type II. Before planning to process river water into clean water, it is necessary to analyze the rate of deposition as the basis for the design criteria that will be used in the planning of the sedimentation basin. The sampling points are at a depth of 10, 30, 50, 70 and 90 cm and the sampling time ranges are 10, 20, 30, 45 and 60 minutes. The results obtained in order to achieve an efficiency of 70% in sedimentation processing, an overflow rate (Vo) of 1.3 m / h is required.

Abstract

Domestic wastewater based on its characteristics is divided into two type which is black water and grey water. Grey water that directly flowed into the environment is one of the main causes of water pollution. The high content of organic matter causes grey water must be treated. Microorganisms can be use to treat this grey water one of them is microalgae Chlorella sp which consume organic matter as a source of nutrients for its growth. In this study, the addition of the Kaldness 1 (K1) biocarrier as a medium for attaching microorganisms were performed on the Sequencing Batch Biofilm Reactor (SBBR) process. Microalgae Chlorella sp. grown as suspended in grey water and attached to Kaldness 1 (K1). This study aims to examine ammonia parameters in grey water. Variations that use in this treatment are reaction times of 60, 90 and 120 minutes and media filling volumes of 0, 20, 40 and 60%. The best results for ammonia removal was 83% in a reactor filled with 20% Kaldness 1 as biocarrier and a reaction time of 120 minutes.Keywords: SBBR, Biocarrier Kaldness 1, Chlorella sp., Grey Water.
