Textile Dyeing Effluents and Environment Concerns - A Review
Open accessAbstract
Textile dyeing effluent is considered as one of the most environmentally unfriendly industrial processes. The study aimed to review the different types of textile dyes use in the industrial processes and their contribution to environmental pollution in South Asian countries. The article was prepared to compile all present data from different journals and website on textile dyeing effluents characterization in South Asia. A wide variety of synthetic dyes like azo dye, vat, reactive dye, disperse dye, etc. widely used in the textile sector. The result showed that some physicochemical parameters of the dyeing effluents (COD, TDS and BOD) exceeded their standard limits. The industrial effluents are affecting the main devastation to the aquaculture, agriculture, ecology, environment, and public health since the development of textile dyeing industries in these countries. Now a day, its proper supervision and curative measures like removal system have become the furthermost thoughtful tasks all over the world and the developing and transition economies countries in particular. It is imperative to take immediate steps to reduce the environmental pollution due to discharge the untreated textile dye effluents. J. Environ. Sci. & Natural Resources, 11(1-2): 131-144 2018
Overview

Written from the paper’s full text.
TL;DR
This review compiles evidence that textile dyeing effluents in South Asia, especially Bangladesh, India, Pakistan, and Sri Lanka, commonly exceed discharge standards for COD, TDS, BOD, and related parameters. It concludes that untreated or inadequately treated effluents pollute water, soil, agriculture, aquatic life, and public health, and that most industries lack effective effluent treatment.
Key findings
- A wide variety of synthetic dyes are used in textiles, including azo, vat, reactive, and disperse dyes; azo dyes constitute 60–70% of all organic dyes produced globally, and over 10,000 dyes and pigments are used industrially with over 7×10⁵ tons of synthetic dyes produced yearly worldwide.
- Reported dyeing effluent parameters frequently exceed standards: Bangladesh effluent EC ranged from 250–7950 μS/cm against the DoE standard of 1200 μS/cm, and BOD/COD values were often higher than discharge standards; India’s Punjab data showed pH 4.30–11.90, COD 120–3000 mg/l, BOD₅ 108–790 mg/l, TS/TSS 450–51450 mg/l, and TDS 430–49440 mg/l; Pakistan’s Faisalabad data showed TDS 2700–4200 mg/L, COD 590–880 mg/L, and BOD₅ 211–487 mg/L.
- Impacts include pollution of aquaculture, agriculture, ecology, environment, and public health; Bangladesh discharges about 40,000 m³/day of textile effluents and 26,000 BOD₅ kg/day pollution load, while Sri Lanka’s coastal textile industries discharge 7100 m³/day wastewater with BOD₅ 4979 kg/day and COD 11310 mg/L, above discharge limits.
- Treatment remains inadequate: most textile and dyeing industries have no effluent treatment plant (ETP), and those with ETPs often do not operate them regularly; a single treatment unit cannot remove all toxic organic and inorganic pollutants, so a series of treatment units is needed.
Methods
- The paper is a review article that compiles existing data from different journals and websites on textile dyeing effluent characterization in South Asia, with particular focus on Bangladesh.
- It presents physicochemical parameters for Bangladesh, India, and Pakistan in Tables 2–4 and uses figures for South Asian textile exports, effluent loads, pH, and TDS; no primary sampling or new experimental analysis is described.
- The main analysis is a narrative synthesis comparing reported effluent values against standards such as DoE, BIS, and NEQS, and discussing environmental and health impacts.
Limitations
- The paper states no explicit limitations.
- Evident from the text: it relies on secondary published and website data, with no described systematic search strategy, inclusion criteria, or quality appraisal.
- Evident from the text: the compiled tables contain missing values and inconsistent parameters/units across countries, and the review offers descriptive comparisons rather than primary sampling or statistical analysis.

“In addition, the enlarged demand for textile yields and the comparative increase in their production and the use of synthetic dyes have contributed to dye wastewater becoming one of the significant sources of severe pollution problems recently (Dos Santos et al., 2007;Ogugbue and Sawidis, 2011).”

Self-check
Percentages, sums and reported differences re-computed from the paper’s own numbers.
Each contradiction between two passages listed here was confirmed by an independent check.
Rated minor: it would not touch a result — a value no result rests on, a p-value that stays on the same side of the significance level, or a conflict that is clerical, resolved elsewhere in the paper, or outside its own findings.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-11-08, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-11-08 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Cited sources are checked with a language model’s help (gpt-6-sol).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
