“…Textile effluents have a higher soluble residual COD fraction, and its slowly biodegradable components undergo hydrolysis with a much slower rate as compared to domestic sewage, which makes it difficult to meet stringent effluent limitations and require biological treatment operated at high sludge age levels. Also, high color content in the effluents of certain operations, require additional treatment involving advanced oxidation processes . A comprehensive treatise of textile wastewaters is also available in a book by Orhon et al …”

BACKGROUND: Despite extensive research on textile wastewaters, very few studies have been devoted to denim processing effluents, basically ignoring the major pumice stone and color problems. This article defined an integrated physical-chemical pre-treatment scheme as a sustainable solution, which would achieve full removal of pumice stone and color, and would provide an optimum adjustment of wastewater characteristics for biological treatment. RESULTS: This survey revealed a strong effluent with 1.0 g L −1 pumice stone (> 2 mm in size); 3.4 g L −1 total suspended solids (TSS) (< 2 mm in size); 1.15 g L −1 chemical oxygen demand (COD) and color 630 platinum-cobalt (Pt-Co) units, as 70 percentile values. Then, two representative samples approximating 70 percentile COD value were taken for laboratory-scale evaluation involving a sequence of preliminary settling and chemical settling experiments. Preliminary settling for 1.0 h reduced the TSS levels to 760-520 mg L −1 and COD to 790-810 mg L −1 for samples 1 and 2, respectively. No appreciable reduction was observed for color. Chemical treatment with polyelectrolyte and poly-aluminum chloride (PAC) exerted significant polishing impact on preliminary settling effluent, achieving almost complete removal of TSS, down to 60 mg L −1 , additional COD reduction to a final level of 335 mg L −1 . Moreover, color could be removed below 7.0 m −1 for all absorbance levels of 436, 525, and 630 nm tested in the experiments. CONCLUSION: The integrated physical-chemical pre-treatment scheme proved to be an effective and reliable approach, yielding an effluent free of TSS and color, with a COD level that can easily be eliminated through biological treatment. CONCLUSIONThe major parameter that differentiates denim processing effluents from the rest of textile wastewaters is the pumice stone content, which displays a complex array of particle size distribution. This significant pollutant, if not effectively eliminated, would J Chem Technol Biotechnol 2020; 95: 142-150

“…. Guyer et al (2016) studied recyclability and direct reuse of washing/bleaching wastewater from reactive dyeing of cotton fabric through advanced oxidation processes (AOPs) such as O3, UV-O3, O3-H2O2, and O3-H2O2-UV. The results showed that the O3-H2O2-UV process removed COD at a higher efficiency (55%) than the other AOPs studied while color removal was similar (>95%).…”

“…Biological methods are extensively applied in the textile industry [10] owing to their benefits such as low cost and ecofriendly concept, however, these treatments do not always meet the objectives due to the non-biodegradability of a wide range of textile dyes [11]. Chemical treatments are the most widely used in the decolorization of textile effluents owing to its ease of application [12,13]. These methods are usually applied at high pH values using ozone, peroxide or permanganate as oxidizing agents.…”

Phenolic resin and waste cotton fiber were investigated as green precursors for the successful synthesis using a soft template approach of a composite carbon with carbon nanofibers embedded in a porous carbon network with ordered and periodically pore structure. The optimal composite carbon (PhR/NC-1), exhibited a specific surface area of 394 m 2 ·g −1 with the existence of both microporosity and mesoporosity. PhR/NC-1 carbon was evaluated as an adsorbent of Alizarin Red S (ARS) dye in batch solution. Various operating conditions were examined and the maximum adsorption capacity of 104 mg·g −1 was achieved under the following conditions, i.e., T = 25 • C, pH = 3, contact time = 1440 min. The adsorption and desorption heat was assessed by flow micro-calorimetry (FMC), and the presence of both exothermic and endothermic peaks with different intensity was evidenced, meaning a partially reversible nature of ARS adsorption. A pseudo-second-order model proved to be the most suitable kinetic model to describe the ARS adsorption according to the linear regression factor. In addition, the best isotherm equilibrium has been achieved with a Freundlich model. The results show that the eco-friendly composite carbon derived from green phenolic resin mixed with waste cotton fibers improves the removal of ARS dye from textile effluents.
