Twelve basidiomycetes were investigated for their ability to degrade 13 industrial dyes and to treat four model wastewaters from textile and tannery industry, defined on the basis of discharged amounts, economic relevance and representativeness of chemical structures of the contained dyes. The best degradation yields were recorded for one strain of Bjerkandera adusta able to completely decolour...

Norit Carbon has developed a chemically regenerable activated carbon (SPARAC) that is suitable for sugar decolourisation. Previous evaluation of this activated carbon showed promising results, and Norit developed another grade of SPARAC that had faster adsorption kinetics. This carbon has been evaluated in terms of its colour removal performance after successive regenerations. Decolourisation t...

Decolourisation of Anionic cum acidic azo dye Amaranth was carried out by an Advanced Oxidation Process Solar/H2O2. Dye samples concentration 100 mg/L taken in 250 ml conical flasks that were treated with 30% H2O2 and exposed to sun light the intensity range 60,000-90,000 lux. The impact various parameters decolourisation like initial concentration, pH, solar intensity, additives temperature st...

Maillard reactions products (MRPs) are a major colorant of distillery effluent. It is major source of environmental pollution due to its complex structure and recalcitrant nature. This study has revealed that sucrose glutamic acid-Maillard reaction products (SGA-MRPs) showed many absorption peaks between 200 and 450 nm. The absorption maximum peak was noted at 250 nm in spectrophotometric detec...

Textile effluents are highly polluting and have variable and complex compositions. They can be extremely complex, with high salt concentrations and alkaline pHs. A fixed-bed bioreactor was used in the present study to simulate a textile effluent treatment, where the white-rot fungus, Trametes versicolor, efficiently decolourised the azo dye Reactive Black 5 over 28 days. This occurred under hig...

In this work, the effectiveness of removing colour and total suspended solid (TSS) from complex organic particulate artificial sewage (COPAS) via coagulation process was studied. Organo-floc (OF), a tannin-based coagulant derived plant used as coagulant. OF applied in jar test experiment at various dosages 57 rpm for 5 min, 30 min sedimentation time to find out optimum dosage TSS removal. Zeta ...

date juice was treated by cross- flow ultra-filtration with molecular weight cut-off (mwco) of 5 kda. optimized levels of feed brix, tmp and operation time were determined as 47.13, 82.11 psi and 30 min, respectively. under such conditions, 80.94% decolourisation and 97.78 % turbidity reduction were obtained while loss of glucose and fructose were estimated to be only 3.49% and 9.62%, respectiv...

Basic Green 4 or Malachite (MG) is an important dye that found great usage in controlling fish pathogens. The use of MG has been banned but developing, and third-world countries still applications for this dye. Bioremediation dyes using microorganisms on the rise. ability to accurately predict rate bioremediation relies upon gathering accurate decolourisation, which often inhibited at high conc...
