In the early days of industrial revolution the waste water generated was simply passed to water bodies like rivers, wells, etc. which was fine for that time as the amount of wastewater generated was very less. The process of dilution was the principle and water purification used to take place by surrounding environment of water called as self-purification of streams. But as soon as the more and more industries were established it was seen that the self-purification process fails to purify water because the quantity of wastewater flown in water bodies was much more than its capacity to purify it. Hence there was a need of effluent treatment plants. Textile industry creates a lot of wastewater having very high amount of color. The color present in water reduces its acceptability aesthetically. Also the color present in water hampers the process of photosynthesis for the plants and other photosynthetic species if directly discharged in water bodies. The textile wastewater also has very high pH, COD, BOD

Textile manufacturing sector is the strongest root of the economy of Bangladesh while pollution by inappropriate management of waste water from textile dyeing industries is one of the major environmental problems. Textile processing employs an assortment of chemicals, contingent upon the idea of the crude materials and items. Environmental problems caused by the the textile industry are mainly the discharges of waste water. The wellspring of waste water contamination are the wet handling steps which incorporate measuring, desizing, scouring, bleaching, mercerizing, coloring, printing etc. The present study was aimed at physico-chemical evaluation of waste water discharged by some garments industries. While in some waste water high pH values have been recorded, the pH values of the waste water before and after treatments were found in between the standard range. The Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solid (TDS) and Total Suspended Solid (TSS) values for waste water before treatment were found to be much higher than the permissible limits. For some industries the BOD, COD, TDS and TSS values of the outlet water from effluent treatment plant (ETP) were also found beyond the standard limits.

Treatment of textile wastewater prior to its discharge into the environment is a highly concerned issue of the industry. The current established methods in textile industry for effluent treatment are typically high in cost, require range of chemicals along with the generation of concentrated hazardous sludge. It is therefore inevitable to look for economical and eco-friendly ways to treat textile wastewater. Hence, the present study was endeavored to develop green, chemical free and sustainable bacteria inoculated plant based technique for remedying textile bleaching effluents. A lab scale floating treatment wetlands (FTWs) system was developed and implemented for remediation of H2O2 based textile bleaching wastewater. This system was designed by vegetating two free floating aquatic plants Eichhorniacrassipes and Pistia stratiotes. The performance of this system was enhanced by inoculating two pollutant degrading and plant growth promoting bacteria, Bacillus cereus and Bacillus subtilis. The efficacy of this bacterial augmented FTWs system was assessed by monitoring physicochemical parameters of treated wastewater. A substantial decrease in pH, EC, TDS, TSS, BOD and COD was noted. This stamped the effectiveness of this sustainable technique to treat textile effluents.

Abstract Textile wastewater from wet processing units is a major environmental problem. Most chemicals including dyes are only partly consumed, resulting in highly colored wastewater containing a variety of chemicals released into the environment. This paper gives information on the current management of textile wastewater in Tanzania. A semiquantitative analysis was done to identify the main types of chemicals used in wet processing units, wastewater characteristics and existing wastewater treatment methods in the textile industry. The performance evaluation of the existing wastewater treatment plants is also discussed. The advantages of integrating constructed wetlands with the existing treatment facilities for textile wastewater are explained. It has been observed that pretreatment and dying/printing of the fabrics are the main two processes that produce wastewater in many textile companies. Main pollutants are chemicals used from pretreatment and materials removed from de-sizing, bleaching and scouring processes. Dyes, printing pigments and dye auxiliaries are the main pollutants from the dyeing/printing process. Most of the textile companies in Tanzania are equipped with effluent treatment plants. Wastewater treatment plants have basically similar units, which are coagulation-flocculation, sedimentation through clarifiers and aerobic reactor. However, their effluents do not meet discharge limits stipulated by the Tanzania Bureau of Standards (TBS).

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

Cotton bandage processing textile industry is the major manufacturing product of Rajapalayam town in south Tamilnadu, India. Processing of surgical cottons consumes significant amounts of water during manufacturing, creating high volumes of wastewater which cannot be discharged without proper treatment. The complete oxidation of organic pollutants in such waste water remains a significant environmental issue. This research investigates different treatment methods like biodegradation and photo catalytic degradation to identify the most efficient and effective approach to treat cotton bandage textile wastewater. Chemical Oxygen Demand (COD) analysis was carried out to quantify and observe the amount of oxidizable pollutant in the waste water with different treatment methods. In photo catalytic degradation process different semi-conductor metal oxide nano particles like Titanium dioxide (TiO2), Zinc Oxide (ZnO) and Bismuth Vanadium oxide (BiVO4) were used. Comparing the three nanoparticles; TiO2 proved to be the efficient one, which reduced the COD of the effluent significantly. For Biodegradation aerobic activated sludge was used to treat the cotton bandage textile waste water in along with mineral salt media. By comparing both photocatalytic degradation and biodegradation process, photo catalytic method was found to be efficient for treatment of organics in real cotton bandage processing effluent.

Textile wastewater (TWW) contains toxic metals that are inimical to microbiome, aesthetic quality, and the health of the receiving freshwater. TWW-impacted freshwater (L2) was assessed for metals eco-toxicity and the consequent impact on microbiome taxonomic profile (MTP) compared to a pristine environment (L1). The conductivity (1750 μS/cm), chemical oxygen demand (2,110 mg/L), biochemical oxygen demand (850 mg/L), and salinity (5,250 mg/L) of L2 were far above the permissible limits. Mercury posed very high ecological risks in the water column of L2 as lead, arsenic, and copper exerted high risk in the sediment. The MTP of L2 revealed the dominance of Euryarchaeota (48.6%) and Bathyarchaeota (45.9%) among the Archaea. The relative abundances of Proteobacteria and Bacteroidetes increased from 38.3 to 2.0%, respectively, in the L1 ecosystem to 42.1 and 12.9%, correspondingly, in L2. Unclassified Eukarya_uc_p (50.4%) and Fungi_uc (16.0%) were key players among the fungi kingdom in L2. The impact of the TWW on the microbiome was evident with the extinction of 6,249, 32,272, and 10,029 species of archaea, bacteria, and fungi, respectively. Whereas, 35,157, 32,394, and 7,291 species of archaea, bacteria, and fungi, correspondingly, exclusively found in L2 were assumed to be invading resident communities that combined with dominant autochthonous strains in shaping the ecophysiology dynamics in TWW-impacted freshwater. While the sensitive microorganisms in L2 are suggested bio-indicators of TWW ecotoxicity, the emergent and dominant taxa are pivotal to natural attenuation processes in the contaminated ecosystem that could be adopted for biotechnological strategy in decommissioning the TWW-impacted freshwater.

Among the activities appointed by the EC research-project “Integrated water recycling and emission abatement in the textile industry” (Contract: ENV4-CT95-0064), the effectiveness of ozone for improving the biotreatability of recalcitrant effluents as well as for removing from them toxic and/or inhibitory pollutants has been evaluated at lab-scale. Real membrane concentrates (pH=7.9; TOC=190 ppm; CDO=595 ppm; BOD5=0 ppm; Conductivity=5,000 μS/cm; Microtox-EC20=34%) produced at Bulgarograsso (Italy) Wastewater Treatment Plant by nanofiltering biologically treated secondary textile effluents, have been treated with ozonated air (O3conc.=12 ppm) over 120 min. The results have indicated that during ozonation, BOD5 increases from 0 to 75 ppm, whereas COD and TOC both decrease by about 50% and 30 % respectively. As for potentially toxic and/or inhibitory pollutants such as dyes, nonionic surfactants and halogenated organics, all measured as sum parameters, removals higher than 90% were achieved as confirmed by the complete disappearance of acute toxicity in the treated streams. The only ozonation byproducts searched for and found were aldehydes whose total amount continuously increased in the first hour from 1.2 up to 11.8 ppm. Among them, formaldehyde, acetaldehyde, glyoxal, propionaldehyde, and butyraldehyde were identified by HPLC.
