Treatment of textile wastewater by chemical methods for reuse

Silica-Supported Co3O4 Nanoparticles as a Recyclable Catalyst for Rapid Degradation of Azodye

“…Therefore, the treating such wastewaters followed by recycling is a big opportunity to decrease both pollution and makes possible to recycle the water in the same industry [1]. For instance, in textile industry, there is a major concern in treating the wastewater and recycling of the treated water [4,5]. Advanced oxidation processes (AOP), such as: Fenton's reaction and photodegradation methods have been practical approaches for degradation of organic pollutants [6,7].…”

Fabrication of perovskite-type oxide La0.5Pb0.5MnO3 nanoparticles and its dye removal performance

“…Textile industry is one of those industries that consume large amounts of water in the manufacturing process [1] and, also, discharge great amounts of effluents with synthetic dyes to the environment causing public concern and legislation problems. Synthetic dyes that make up the majority (60-70 %) of the dyes applied in textile processing industries [2] are considered to be serious healthrisk factors.…”

“…On the contrary, the technology of nanoparticulate photodegradation has been proved to be effective to them. Compared with the other conventional wastewater treatment means, this technology has such advantages as: (1) wide application, especially to the molecule structure-complexed contaminants which cannot be easily degraded by the traditional methods; (2) the nanoparticles itself have no toxicity to the health of our human livings and (3) it demonstrates a strong destructive power to the pollutants and can mineralize the pollutants into CO 2 and H 2 O. Due to the excellent features of this technology, it appears promising and has drawn the attention of researchers of at home and abroad [10][11][12].…”

Textile Organic Dyes – Characteristics, Polluting Effects and Separation/Elimination Procedures from Industrial Effluents – A Critical Overview

“…There are reported very effective chemical coagulation-flocculation (C-F) and precipitation of textile wastewater which reduced the load on the biological treatment, working with polyaluminium chloride along with an organic polymer (Lin & Chen, 1997) or ferrous/ferric chloride and a commercial organic coagulant aid at pH of 6.7-8.3 (colour removal > 80%) (Venkat Mohan et al, 1999) or alum at pH=8.2 (54-81% colour removal) with addition of bentonite (3 g/L) for Remazol Violet dye-containing effluent (Sanghi et al, 2001). Other efficient textile treatments mentioned by different textile operators consist in coagulation-flocculation followed by membrane technology (especially for recycling textile effluents).…”
