Laboratory biofilm reactors are tools that researchers use to grow biofilms that exhibit characteristics sufficiently similar to the environment of interest. Numerous biofilm reactors that model various fluid dynamics are described in scientific literature, each with its associated list of advantages and limitations. This chapter focuses on the process used to design and fabricate biofilm reactors with the stated goal of generating a commercial product. The process begins with identifying the environment of interest and key attributes the reactor should include or model. A prototype is then designed, built, and tested in the laboratory. Modifications are made based upon laboratory performance until a design is achieved that is affordable, practical, operationally simple, and relevant and that provides repeatable, convincing results. This process was used to design the industrial surfaces biofilm reactor, developed to model cooling tower biofilms but suitable to study biofilms grown under low shear, high gas transfer, and intermittently wet conditions.
