Wyoming is lack in water resources. Aquifer storage and recovery (ASR) through water injection could be an important method to solve the water problem in Wyoming. However water injection could lead to contamination of ASR due to the leaching of heavy metals and other elements. Therefore prediction of the potential of leaching of contaminants with a model is critically important to the successes of the application of ASR technology in Wyoming and other states in the U.S.
The proposed project is designed to provide a solution to the universal issue facing many potential ASR technology customers, which is based on the physical and chemical properties of rocks and waters to be used and chemical engineering's kinetic theories. Both batch leaching and continuous flow leaching models are going to be developed. The purpose of developing batching model is to obtain necessary kinetic parameters for development of continuous flow leaching model. The continuous flow models (for multi species) will not only be developed but also be tested under various contaminant leaching conditions.
