Colour Removal From Dye Effluent Using Activated Carbon From Tamarind Shell

In 21st century, water pollution due to textile dye industry has turned into a severe problemaround the world including India. The dye industry in India is made up of about 85 largeorganized units and 4,000 small scale units, they produce around 1,60,000tonnes of dyestuffper month. These direct discharges of dye wastewater effluent into waterbodies like lakes,rivers and other water pollution will affect plants and animals. The aim of our research is toprepare activated carbon from tamarind shell with surface modification by chemicallyactivating method in optimum conditions with distilled water. Availability, cheapness andadsorption capacity are the key factors for choosing tamarind shell as a particular source foractivated carbon. The study undergoes the effects of contact time, powdered activated carbondosage, and effect of rpm in adsorption between chemically activated carbon and dye wastewater. The amount of activated carbon yield from the tamarind shell is 59.5% and it is alsocheaply available waste material. The maximum removal efficiency of 99.7% was achievedat 60 rpm with optimum contact time 90 minutes and optimum dosage of 5g powderedactivated carbon.
