Removal of Iron from Real Waste-water Using Rice Husk Activated Charcoal

Abstract

Heavy metals, when in abundance, can be very toxic to the medium in which it is dissolved. Adsorption has been used as a suitable water treatment process to remove heavy metals. Many studies have been conducted to remove these heavy metals by using different materials. Different materials have different chemical constitutes, hence, a material that is very effective in removing one heavy metal may prove to have a poor efficiency in adsorbing, or removing, another metal.For This research,Rice Husk Activated Charcoal was prepared From raw rice Husk and removal of iron  was Done From the real waste-water from H.D. wire,Sanwer industry.rice Husk was grounded to fine size then treatment with acid was done and it was kept in hot air oven for one day then basic treatment was done with the help of sodium hydroxide and then it was kept in hot air oven for one day.then final rice husk activated charcoal was prepared. Then five waste-water sample were taken of different days and there various parameters were calculated such as pH,electrical conductiivty,turbidity,chemical oxygen demand and chloride content. Iron content of five sample were determined and after mixing with rice husk activated charcoal for two hours sample were filtered then with different dosing of rice husk activated charcoal were used to know the iron removal efficiency with the different dosing of rice husk activated charcoal and optimum dosage of rice husk activated charcoal was found.further investigations may need to be performed to obtain results on Different parameters,adsorbent particle size,contact time,agitation speed and temperature etc.
