Battery manufacturing, metal plating, mining, pigment dye stuff, and chemical industries discharge many heavy metal ions into industrial wastewaters (Volesky 1990).
The drug is a synthetic chemical derived from dye stuff and is said to kill germs which have entered the blood stream.
There are more than 10,000 commercially available dyes with over 7 × 105 tonnes of dye stuff produced annually.
A recent investigation in Tirupur has suggested the contamination of soil and sediment of river bed by different metals and dye stuff and also the adaptability of native microbial community to decolorize the color of effluent.
The fate of dye stuff was investigated in biologically based primary treatment to understand the mechanism of biological potential in activated sludge and it was found that partial color removal was achieved by adsorption of the dyes to the sludge (even though they were water soluble).
Still, by the time the last note of the nearly three-hour show had been struck, the last noodle noodled, the last jam jammed, I was fucking devout, ready to trade in all of my regular shirts for exclusively tie-dye stuff.
As observed in Figures 2 and 3, fungal biomass shows frequent leaching of the dye stuff into the liquid medium which is especially prominent in case of dye reactive red 31.
Complete adsorption of dyes to fungal biomass was observed after 15 days of incubation as no residual dye stuff was left in the medium except for dyes reactive green 19 and reactive black 8 at concentrations more than 200 ppm (Table 1 and Figure 3).
It is not possible to avoid faded tapestries altogether, because certain of the dye-stuffs are simply not permanent.
