Successive alkalinity producing system column study for alkalinity generation capacity with respect to influent AMD quality

Authors : M. D. Patel



Water pollution due to Acid Mine Drainage (AMD) is becomes a matter of serious concern globally, which is a by-product of mining operation. AMD is harmful to aquatic life and corrodes the pumps, pipes and other machinery in mines; hence AMD should be managed economically and in efficient manner. The AMD discharge concentration should be in permissible limit as per requirement of various environmental laws in different countries. There are varieties of methods under active and passive treatment system for AMD treatment. Successive Alkalinity Producing System (SAPS) is widely accepted method, which incorporate the advantage of Anoxic Limestone Drain (ALD) method and wetland system. In this paper experimental studies were conducted using cow compost regarding performance of SAPS with respect to iron, aluminum, manganese removal and alkalinity generation. During this study four different types of synthetic AMD were used as influent and performance of SAPS for different Hydraulic Retention Time (HRT). It has been observed that both iron and aluminum is completely eliminated whereas removal of manganese is limited to 35.33%. In this article the author also make effort to analyze metal removal trends and alkalinity generation response by SAPS cell.
