Reactive Transport: A Review of Basic Concepts with Emphasis on Biochemical Processes

Reactive transport (RT) couples bio-geo-chemical reactions and transport. RT is important to understand numerous scientific questions solve some engineering problems. highly multidisciplinary, which hinders the development of a body knowledge shared by modelers developers. The goal this paper review basic conceptual issues all problems, so as facilitate advancement along current frontier: biochemical reactions. To end, we equations indicate that chemical systems are controlled set equilibrium reactions, easy model, but whose rate mixing. Since mixing not properly represented standard advection-dispersion equation (ADE), conclude poor for RT. This leads us alternative formulations, methods problems using both ADE equations. easy, difficulties arise kinetic especially true biochemistry, where challenges open (how represent microbial communities, impact genomics, effect biofilms on flow transport, etc.). We with eleven consider fundamental any conceptually sound effort.
