Tannery effluent is among one of the hazardous pollutants of industry. Major problems are due to wastewater containing heavy metals, toxic chemicals, chloride, lime with high dissolved and suspended salts and other pollutants. Tanneries generate wastewater in the range of 30 - 35 L/kg skin / hide processed with variable pH and high concentrations of suspended solids, BOD, COD, tannins including chromium. Chromium is the major constituent of tannery effluent, which is the heavy metal and highly toxic to aquatic fauna. Chromium is not known to accumulate in the bodies of fish, but high...

Reactive dyes are synthetic dyes, which are increasingly used in the textile industries because of their ease and cost effectiveness in synthesis, firmness and variety in color. The strong color of discharged dyes even at very small concentrations has a huge impact on the aquatic environment caused by its turbidity and high pollution strength. In recent years, there has been an intensive research on fungal decolourization of dye wastewater. It is becoming a promising alternative to replace or supplement present treatment processes. This book experimentally explains various fungi, living or...
