Electrocoagulation method for textile dye wastewater treatment was investigated in this study. Results show that electrocoagulation can be used powerfully and effectively in organic matter degradation of textile industrial wastewater, where the extent of COD removal and decolorization are achieved about 75.45% and 84.62% after 25 minutes, respectively. pH for textile dye wastewater ascended higher than that of raw wastewater and temperature increased with electrolysis time. GC-MS spectra suggest that organic pollutants in textile dye wastewater are effectively oxidized and decomposed by direct current electrolysis. In addition, the quality of the upper layer liquid after electrolysis nearly meets the criteria of Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry (GB4287-92) of China.

In this study, the effects of the phosphonic acid based sequestering agent EDTMPA used in the textile dye baths on colour and organic matter removal by ozone oxidation was experimentally investigated. Procion Navy HEXL dyestuff that has been commonly used for the reactive dyeing of cellulose fibers was selected as the model component. The organic matter oxidation by ozone was determined to obey the pseudo-first order kinetics as they are treated singly or in combination. COD removal rates obtained from pseudo-first order reaction kinetics showed that oxidation of Navy HEXL alone (0.0947 L/min) was faster than that of EDTMPA (0.0171 L/min) and EDTMPA with dye (0.0155 L/min) at pH 3.0. It was also found that reaction rates of single EDTMPA removal and EDTMPA and dye mixture removal increased as the reaction pH was increased from 3.0 to 10.5.

The aim of this work was to determine the depuration efficiencies of an infiltration percolation plant to remove organic matter and nutrients (N and P) and to test the effect of treatment by such system on the fertilizer value of wastewater compared to untreated influent and a control (groundwater). Results of investigations carried out over a month of each season showed the high capacity of this depuration system to remove both particulate and dissolved organic matter (TSS 91%, COD 93% and dCOD 89 to 95%) at all season. Nitrogen and phosphorus were more eliminated at winter and summer. At spring they presented a low percent removal efficiency due probably to overloaded influent. Tests consisting in the reuse a raw wastewater (RW), settled wastewater (SW) or completely treated wastewater (FW) for irrigation of (Lolium perenne) plots showed that biomass yield, nutrients (N,P) exported by plants and protein amount in the plants tissue decreased from plots irrigated by (RW) to completely treated wastewater. But all of them were more important than in the control plants (irrigated by groundwater) and exceeded the mean values reported in literature for meadows plants. The amount of nitrogen and P2O5) applied during the irrigation by wastewater, was equivalent or superior to recommanded dose of fertilizer for meadows. The expected meat or milk production showed a promising potentiality to promove the nutritional quality of farm animals food by using treated wastewater.

Raw Wastewater

Vertical flow constructed wetlands for small communities (<5,000 population equivalent) have been successfully developed in France since the 1990s (currently about 3'000 plants are in operation). This paper summarizes the results and efficiencies of 70 plants designed and built by Epur Nature or SINT. The results show clearly that the design performs well for organic matter removal and nitrification and makes sludge management easy. Therefore if well designed, such systems can achieve an outlet quality of BOD5 < 20 mg/L, chemical oxygen demand <90 mg/L, suspended solids <30 mg/L and TKN < 15 mg/L. In addition, some new configurations involving a French vertical first stage fed with raw sewage, patented by Epur Nature, are presented as an aid to reduce the global footprint.

Abstract Synthetic dyes, particularly reactive and acid dyes, are commonly used in the textile industry because of their advantages as excellent color fastness and brightness. Also, surfactants are used for an increment of coloring success in the textile industry. One of the major problems concerning textile wastewater is the treatment of the effluents containing both dyes and surfactants. Biological treatment systems are recommended as useful, economic and eco-friendly methods for treatment of industrial wastewater. The purpose of this study was to investigate the binary removal of a textile dye and a surfactant by growing Aspergillus versicolor culture in molasses medium. The effect of dye and surfactant concentration on the removal of dye and surfactant was determined. This study resulted that 100% of the surfactant and dye molecules removed together with the formation of a dye-surfactant complex by fungus. It is concluded that binary removal systems are very efficient for industrial wastewater treatment.

This study aimed to understand the degradation pattern of organic substances through different amount of red worms during vermicomposting of cattle manure. For this purpose, an experiment was conducted with three treatments e.g., T1 (vermicomposting of 25 kg cowdung using 50 g of red worms), T2 (vermicomposting of 25 kg cowdung using 100 g of red worms) and T3 (vermicomposting of 25 kg cowdung using 150 g of red worms) with 3 replications. Parameters studied were dry matter (DM), organic matter (OM), ash, organic carbon (OC), total nitrogen (TN), crude fiber (CF), carbon nitrogen ratio (C/N) and pH at different days of intervals. Results showed that the amount of red worms has a significant influence on the quality of the final vermicompost. The highest DM content was observed in T3 and the lowest DM content was observed in T1 after 45 days of composting. There were significant (p<0.001) higher reduction rate of OM, OC and CF were found in T3 compared to T1 and T2 and the differences were also significant (p<0.001) among days intervals over 45 days of experimental period. TN content gradually increases with the increase of time. There was significant (P<0.05) difference in TN alteration among treatments along with time intervals. There was significant differences (P<0.001) in C/N among treatments and a gradual increment of C/N was found with the advancement of the vermicomposting. There were a little changes in pH of all the treatments but those treatments were not followed a trend during the total experimental period. Finally, it may be concluded that organic matter degradation rate is faster in T3 compared to T1 and T2. These might be indicated that amount of red worms are an important factors of OM decomposition or digestion during vermicomposting period. Bang. J. Anim. Sci. 2020. 49 (1): 45-54

ABSTRAKIndustri pemanfaatan kayu cukup sering ditemukan di Indonesia, namun limbah yang dihasilkan tidak diolah dan hanya dibuang ke lingkungan. Limbah serutan kayu yang mengandung rantai karbon dapat dimanfaatkan menjadi karbon aktif. Pengaruh kualitas karbon aktif dari serutan kayu ini diuji berdasarkan waktu aktivasi dan daya adsorpsi limbah cair. Karbon aktif dibuat melalui pirolisis hingga mencapai suhu 5000C dengan ukuran 100-150 mesh dan diaktivasi dengan H3PO4 10% selama 6 jam, 12 jam, dan 18 jam. Karbon aktif yang dihasilkan digunakan sebagai adsorben dan diujikan pada limbah cair zat warna tekstil Sumikaron Yellow Brown S-2RL. Adsorpsi dilakukan dengan variasi waktu 1 jam, 2 jam dan 3 jam. Selanjutnya larutan zat warna yang telah dijerap oleh karbon aktif dianalisa menggunakan spektrofotometer dengan panjang gelombang 480nm. Berdasarkan absorbansi atau konsentrasi (%) pengurangan warna yang dihitung menggunakan anova dengan software Minitab 17, pengaruh yang lebih signifikan dalam pemanfaatan karbon aktif dari serutan kayu yaitu pada waktu aktivasi 12 jam dan waktu adsorpsi 3 jam. Karbon aktif dari limbah serutan kayu mampu mengurangi limbah cair zat warna sebesar 98,2519%. Hasil uji pendahuluan dengan menghitung bilangan iod dari adsorben karbon aktif yang telah diaktivasi selama 12 jam menjadi kondisi terbaik dengan menjerap iod sebanyak 144,8961 mg/g.Kata Kunci: limbah cair, karbon aktif, serutan kayu, MinitabABSTRACTThe wood utilization industry is quite often found in Indonesia, but the waste produced is not processed and is only disposed of into the environment. Wood shavings containing carbon chains can be used as activated carbon. The effect of the quality of activated carbon from wood shavings was tested based on the activation time and adsorption liquid waste’s capacity. Activated carbon is made through pyrolysis to reach a temperature of 5000C with a size of 100-150 mesh and activated with 10% H3PO4 for 6 hours, 12 hours, and 18 hours. The activated carbon produced was used as an adsorbent and tested on the liquid waste of textile dye Sumikaron Yellow Brown S-2RL. Adsorption is carried out with variations of 1 hour, 2 hours and 3 hours. Furthermore, the dye solution that has been absorbed by activated carbon is analyzed using a spectrophotometer with a wavelength of 480nm. Based on the absorbance or concentration (%) of color reduction calculated using anova with Minitab 17 software, a more significant effect on the utilization of activated carbon from wood shavings is the activation time of 12 hours and the adsorption time of 3 hours. Activated carbon from wood shavings waste is able to reduce dye wastewater by 98.2519%. The results of the preliminary test by calculating iodine number from the adsorbent of activated carbon which has been activated for 12 hours are the best conditions by absorbing iodine is 144.8961 mg/g.Keywords: liquid waste, activated carbon, wood shavings, Minitab

The textile dye wastewater removal in the environment is a greater problem by its harmful reasons. Dyes which obstruct the penetration of light leads to damage the quality and produce the poisonous effect in the aquatic ecosystem. Several studies were proved that the physicochemical methods were employed for treating the textile dye wastewater. Hence the biological processes are employed for treating the textile dye wastewater due to its cost effectiveness and less toxic effects. Bio filter can be an effective solution for producing high quality water and saving water for recirculation. In this article fujino spirals were mainly focusing as media in the reactor and operated at a hydraulic retention time (HRT) of 24h. The purpose of this study to analysis the overall performance of the UASBR which is achieved the maximum COD removal at 24hrs HRT respectively. From this study results, percentage of COD removal is directly related to the HRT. Hence the UASBR is suitable for treating real textile dye wastewater even upto 1000mg/l efficiency
