In order to simulate microbially influenced mineral precipitation process, a 1D reactive transport model is developed. The developed reactive-transport model consists three components: MATLAB (main stream), ORCHESTRA (equilibrium reaction processor) and EXCEL (user interface). The established model as a generic tool enables the simulation of one-dimensional flow transport in the subsurface porous environment undergoing complex biochemical reactions. Possible reactions include the kinetic phase mineral precipitation, chemical speciation reactions, kinetic biomass related reactions and gas-liquid equilibrium. Unlike other models where physical transport medium properties are assumed to be constant, these properties in this model is interconnected with bio-chemical reactions as the response to the accumulation of precipitated minerals and biomass.
