Backward-Facing Step

摘要

Systems, methods and media for carbonation of fluid in an algae cultivation pond via the use of backward-facing steps are disclosed. In a first aspect, a method for initiating carbonation of a fluid flow in an algae cultivation pond is disclosed. Fluid flow is initiated over a backward-facing step in the algae cultivation pond. A backflow region is generated in the fluid flow downstream of the backward-facing step. Carbon dioxide is provided to the backflow region.
