The residual dyes from different sources (e.g., textile industries, paper and pulp industries, dye and dye intermediates industries, pharmaceutical industries, tannery, and Kraft bleaching industries, etc.) are considered a wide variety of organic pollutants introduced into the natural water resources or wastewater treatment systems. One of the main sources with severe pollution problems worldw...

This paper presents the review of the effects of operating parameters on the photocatalytic degradation of textile dyes using TiO2-based photocatalysts. It further examines various methods used in the preparations of the considered photocatalysts. The findings revealed that various parameters, such as the initial pH of the solution to be degraded, oxidizing agents, temperature at which the cata...

Polygalacturonases (PGases) or hydrolytic depolymerases are enzymes involved in the degradation of pectic substances. They have a wide range of applications in food and textile processing, degumming of plant rough fibres and treatment of pectic wastewaters. Bacteria, yeasts and fungi under both submerged (SmF) and solid-state fermentation (SSF) conditions produce these enzymes. Bacteria produce...

Considerable amount of unconsumed dyes from textile, paper and printing industries are being discharged into water bodies, every day. The presence of dyes and pigments in water causes considerable damage to the aquatic environment [1]. These contaminants result in high chemical oxygen demand (COD), high biochemical oxygen demand (BOD), toxicity, bad smell, and are mainly responsible for the col...

Background and purpose: Textile effluents are very difficult to treat satisfactorily due to high variations in their compositions. Strong color is one of the main characteristics of textile effluent and, if not eliminated, it can cause serious problems to the environment. In the present study, multi-walled carbon nanotubes (MWCNTs) were used as an adsorbent for the removal of Reactive Red-120 (...

Synthetic and bioinspired metalloporphyrins are a class of redox-active catalysts able to emulate several enzymes such as cytochromes P450, ligninolytic peroxidases, and peroxygenases. Their ability to perform oxidation and degradation of recalcitrant compounds, including aliphatic hydrocarbons, phenolic and non-phenolic aromatic compounds, sulfides, and nitroso-compounds, has been deeply inves...

Haematological and serum biochemical studies on Swiss albino rats were carried out for a period of 15 days to investigate the effects of untreated (Infl uent) and treated (Effl uent) textile dye wastewaters collected from an Effl uent Treatment Plant in Sanganer, Jaipur, India. In comparison to control animals (potable water), values of RBC, WBC, Hb, PCV and MCHC decreased signifi cantly in was...
