The rapid growth in the population is the main reason for today’s water pollution in the sources of water, which would be creating the stress in the water throughout the world. Treatment of waste waters of the industries which would be having the contaminated metals in them will be involving the techniques like reducing the toxic in water for meeting the standards set by the authorities or government. Various treatments for the removal of heavy metals from industrial wastewater have been evolved. The adsorption commonly used method for reducing the pollutant in the water totally, the fundamental process of physicochemical treatments in the wastewaters that is economically meets higher effluent standard. The activated charcoal is one of the oldest also a widely used for the adsorbent of water for treatment by removing both the organic and the inorganic pollutants. This method is activation, with the nature of precursors which greatly influences the surfaces of the functional group with pore structured activated charcoal. Despite having many techniques for the purification of water the adsorption is the fastest, less expensive and is also known as the universal technique. In this paper we have mainly concentrated on the various recently developed methods for wastewater treatment through activated charcoal.
