Textile effluent contains different organic and inorganic pollutants, among these are COD and heavy metals such as lead (Pb), chromium (Cr), cadium (Cd), and copper (Cu) used for the production of color pigments. In this study the adsorption capacity of chitosan produced from snail shells as an adsorbent for the treatment of textile effluent and for the removal of lead (Pb2+) from waste water carried out. Batch experiments were performed to study the treatment of textile waste water and the adsorption of lead Pb2+ion unto chitosan. The effect of various experimental parameters (adsorbent dose, contact time and temperature) was studied, and optimal conditions were determined. Batch adsorption study on textile waste water showed 96.9 % COD removal was achieved for carbon dosage of 15mg carbon/100ml of textile wastewater solution. The equilibrium data were analyzed with Langmuir, Freundlich, Temkin, Elovich, Florry Huggins, Jovanovic, Harkin Jura and Dubinin–Radushkevich (DRK) adsorption models. Freundlich isotherm yielded the best fit to the experimental equilibrium adsorption data with a correlation coefficient (R2 ) of 0.991. The adsorption intensity is 1.68. This was closely followed by Langmuir Isotherm with a correlation coefficient (R2 ) of is 0.943. The maximum monolayer coverage (Qo) from Langmuir isotherm model was determined to be 50.51mg/g, KL (Langmuir isotherm constant) is 0.00374L/mg, RL (the separation factor) is 0.217 indicating that the equilibrium sorption was favorable. Adsorption kinetics data for sorption of Pb2+ion unto chitosan were analyzed using the pseudo first order, pseudo second order and intra particle diffusion models. The results indicated that the adsorption kinetic data were best described by pseudo secondorder model. For the thermodynamic studies, the enthalpy change, ΔH°, and the entropy change, ΔS°, for the adsorption processes are -18.10 kJ/mol and -0.0652KJ/mol K respectively. The free energy, ΔG° for the process are 2186.39 J/mol, 3071.761 J/mol, 3689.615J/mol and 4153.032 J/mol at 303K, 313K, 323 K and 333K respectively. The results of thermodynamic parameters evaluated showed that the process was non spontaneous and exothermic in nature. The results show that chitosan can be used as an alternative low-cost adsorbent for treatment of textile effluent and the removal of COD and lead from wastewater.

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

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

The adsorption of levafix red (LR) dye from waste water via batch adsorption onto treated jute stick powder was investigated. Studies concerning the factors influencing the adsorption such as adsorbent dosage, pH, contact time and temperature were systematically investigated and discussed. The results revealed that the maximum removal of levafix red was ~91% from water. The kinetics data were analyzed using pseudo-first order and pseudo-second order models. It was best described by the pseudo-second order model. The adsorption equilibrium follows Langmuir isotherm. This result indicates that treated jute stick powder could be employed as low-cost alternatives to commercial activated carbon for the removal of levafix red (LR) from waste water. Rapid industrialization in Bangladesh has resulted in increased water pollution that has higher dye level. Waste water from dyeing and finishing factories is a significant source of environmental pollution. The waste water is typically characterized by high levels of COD (chemical oxygen demand) concentration, high concentration of coloring material, large amount of suspended solids, highly fluctuating pH and high temperature. Dyes may therefore present an ecotoxic hazard and introduces the potential danger of bioaccumulation that may eventually affect man by transport through the food chain. As pharmaceutical industries use lots of water and intake of this type of water might have adverse effects on human health. Therefore, water purification is extremely essential for human and animal health and dye free water may be farther purified for its proper use.Bangladesh Pharmaceutical Journal 19(1): 75-84, 2016
