Water Treatment

Water treatment is performed in order to improve water quality. The processes employed for water treatment depend on the quality of the water supply. In all cases, water has to be disinfected in order to deactivate any existing microorganisms present in water. So far, this technique was proved to be the most important for the protection of human life. It is commonly done using chlorine or ...

A Calibrated Predictive Geochemical Model of Leaching and Attenuation Reactions in a Mine Pit Lake

Abstract: A geochemical model was developed to predict future water quality of the Cove pit lake in support of site closure and regulatory permitting. The terminal, groundwater-fed Cove pit lake began filling in 2001, and water-quality samples from the 15-year filling period were used to calibrate the pit-lake model and evaluate the accuracy of the predictions. Inputs to the pit-lake model ...
