Waste water from the textile industry is one of the major sources of contamination causing serious health problems. In textile waste water, dyes are the main pollutant. In this research work textile waste water was treated with various organic acid-activated clays to remove the dyes. Pink Azo dye was selected as a component to remove from waste water. Adsorbent selected was bentonite clay and was activated by acids such as phosphoric, acetic, oxalic, and citric acids. Adsorbent characteristics have been analyzed through infrared spectroscopy (FTIR) and Scanning Electron Microscope (SEM) while the removal of dye at various temperatures has been analyzed through Ultraviolet (UV) analysis. It was observed that the bentonite clay-treated with phosphoric acid had relatively maximum capacity to remove the dye while the clay treated with oxalic acid got minimum capacity to remove the dye from same waste water.

Decolorization of Sumifix Blue and Reactive Red 2 Textile Dyes by Microbes Isolated from Textile Waste WaterAzo dyes represent the most commonly used group of dyes in textile industry and discharged into industrial effluents worldwide. Aims of this study are to isolate microbe from textile waste water and to determine their ability to decolorize Sumifix Blue and Reactive Red 2 textile dyes. Microbe was isolated from textile effluent of PT Timatex, Salatiga. The activity for decolorization was assayed by inoculating microbial isolates into dye containing medium. Living and nonliving cell were incubated in dye containing medium in order to determine if microbial cells involved in decolorizing dye. Five different microbial isolates have been isolated from textile waste water.  Isolates IBLTT_1 and IBLTT_5 showed the highest activity to decolorize Sumifix Blue, and only isolate IBLTT_1 showed the highest capability in decolorizing Reactive Red 2. Both isolates indicated positive potential towards biotreatment of textile waste water. Further results confirmed that decolorization was due to biodegradation, rather than physical adsorption by inactive cells.Keywords: decolorization, microbial isolation, Reactive Red 2, Sumifix Blue, textile effluent ABSTRAKPewarna azo mewakili kelompok pewarna yang umum digunakan pada industri tekstil dan banyak dijumpai di buangan limbah industri tekstil. Tujuan dari penelitian ini adalah untuk mendapatkan isolat dari limbah tekstil dan untuk mengetahui kemampuannya dalam mendekolorisasi pewarna tekstil Sumifix Blue dan Reactive Red 2. Sampel diperoleh dari limbah industri tekstil PT Timatex, Salatiga. Uji kemampuan dekolorisasi dilakukan dengan menginokulasikan isolat mikroba ke dalam medium Nutrient Broth yang mengandung pewarna. Untuk mengetahui apakah sel mikroba terlibat dalam dekolorisasi pewarna, maka sel hidup dan mati diinokulasi pada medium tersebut. Lima isolat yang berbeda diperoleh dalam penelitian ini. Isolat IBLTT_1 dan IBLTT_5 merupakan isolat dengan kemampuan dekolorisasi Sumifix Blue tertinggi. Isolat IBLTT_1 juga merupakan isolat dengan kemampuan dekolorisasi Reactive Red 2 tertinggi. Kedua isolat tersebut menunjukkan potensi positif terhadap pengolahan limbah tekstil. Hasil lebih lanjut menegaskan bahwa dekolorisasi Sumifix Blue dan Reactive Red 2 disebabkan oleh proses biodegradasi, bukan diadsorpsi oleh sel yang mati.Kata kunci: dekolorisasi, isolat mikroba, limbah tekstil, Reactive Red 2, Sumifix Blue

During the last decade, Bhilwara has developed into a leading place in the textile industry in India. The water used in textile industry is almost entirely discharged as waste. The effluents are very complex, containing salt, surfactants, ionic metals and their metal complexes, toxic organic chemicals, biocides, and toxic anions, which are harmful to both flora and fauna existing on our planet. Degradation of these non-biodegradable organic compounds is not possible by conventional treatment processes. The analysis of waste water with different quality parameters and photocatalytic bleaching was examined by using UV light in photochemical reactor with SnO2 catalyst.

The degradation and decolouration of textile waste water by gamma irradiation has been studied. Textile wastewater contain a mixture of dyes that difficult to degrade using conventional method, therefore it is necessary to find another method to degrade those dyes. Samples from effluent of textile industry were taken at certain time and have different in colour and condition. The addition of coagulant and radiation to remove the colour of the samples were demonstrated. Four kind of treatments were carried out in this experiment namely addition of coagulant, radiation, variation of pH and radiation, and combination of radiation with the addition of coagulant. The parameters examined were the change of spectra intensity, percentage of sedimentation after the addition of coagulant, and the percentage of the degradation. Combination of irradiation and the addition of coagulant induced decolouration and degradation of the waste.   Keywords: radiation, degradation, decoloration, textile wastewater

Electrocoagulation methods are being used for the alternative treatment process for the remediation of textile waste water. This work primarily deals with the treatment of textile dyeing waste water followed by the utilization of waste material. The purpose of the proposed study is to evaluate the potential of electrocoagulatison process using Ti2O3/Zn electrode prepared by spray pyrolysis using TiCl3 and compared the performance with Zn electrodes. The surface morphology, structural analysis and percentage composition of the elements of the Ti2O3/Zn electrode was studied by SEM, XRD and EDS analysis. The efficiency of electrocoagulation treatment process to treat synthetic waste water containing Coralene Navy RDRLSR, Coralene Red 3G, Rubru RD GLFI dye was studied for the effect of operational parameters. The result indicates that this process was able to achieve colour removal (97.2 %) at pH 8.5, with 34.42 % less energy consumption with Ti2O3/Zn compared with zinc electrodes.
