Currently, arsenic contamination in drinking water is an emerging issue around the world. Arsenic contamination is severe threat to the environment and human beings. Several researchers and organizations standardized the arsenic levels in drinking water. This research focuses on the effect of accelerated carbonation process for successful removal of heavy metal arsenic anions from artificial waste water and we applied this technology was going to be apply to the real waste waters. This accelerated carbonation process is a simple, economic and ecofriendly process with 85 ~ 88% removal efficiency and also it improves immobilization of solidified/stabilized the heavy metals.
