Phosphorus is the element that promotes growth in plant. However, over loading of phosphorus into surfaces water leads to severe environmental problems known as eutrophication. Improper treatments removal prior discharges from industrial effluent are one contributions Textile sources surface with concentration 1-9 mg/L P. Since attentions given removing color effluent, commonly ignored wastewat...

Dye decolorizing bacteria was isolated and identified from textile effluent samples. The isolate was identified as Bacillus licheniformis by 16S rDNA sequencing. Azoreductase, an enzyme responsible for catalyzing the reductive cleavage of azo bonds was purified from B.licheniformis. The enzyme was purified by a combination of ammonium sulphate precipitation, ion exchange and affinity chromatogr...

Textile waste water treatment for industrial reuse remains as a complicated problem due to several reasons. Among them are: 1) Higher levels of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS) content of the waste water; 2) Non-biodegradable nature of organic dye stuffs present in the effluent. Thus, any adopted treatment system, especially with resp...

The adsorption of textile dyes by clay was investigated using basic dye (Methylene Blue). Adsorption of dye effluent onto clay samples was carried by batch studies at room temperature, 25oC. The effects of adding clay with zeolite, pH and shaking time towards adsorption performance were investigated. The results from the mixture of 1.0 g clay and 0.01 g zeolite, the increases of pH, pH 9 and th...

An efficient photocatalyst consisting of CdS nanoparticle dispersed mesoporous silica-titania was prepared using amphiphilic triblock copolymer P123 as template and silica-titania sol–gel precursors. The CdS nanoparticle was incorporated into silica-titania mesoporous nanosturctures by post impregnation method. The synthesized catalyst has been characterized by FTIR, TEM, SEM, and EDAX analysis...

A new spectrophotometric method involving flow injection analysis and textile dye aggregation effect is proposed. The method is based on the aggregation effect of Blue Procion HEGN at pH 3, which relocates its maximum absorption wavelength from 620 to 776 nm, avoiding the interference of other blue textile dyes. For this task, a simple and robust flow injection system was designed, which became...

SOURCE REDUCTION OF CHEMICALS IN TEXTILE PRINTING This is a wide-ranging subject that is now becoming of increasing importance. Allprintersare aware of thegreater pressure being placed on them by both national and local government legislation on the environment. This legislation is aimed at reducing emission from flues and controlling and monitoring the discharge of effluents. In the past the t...

Abstract--Textile dying industry effluents are highly toxic in nature and it contains a large number of complex metal dyes. Many dyes used in textile industries are stable to light and resistant to aerobic digestion. Thus removal of coloured waste from industrial dye effluent is a most perplexing problem to such industries and the environment. On the other hand fly ash is a major pollutant gene...
