Disclosed are an apparatus for forward beamforming using a terminal feedback and a method thereof. To conduct this reaction it is necessary to culture both autotrophic ammonia oxidizing bacteria as well as facultative heterotrophic bacteria such that the facultative heterotrophs can denitrify the oxidized ammonia compounds produced by the autotrophic bacteria as they are produced. A receiving structure is located between the immovable portion and the movable portion for receiving the heat pipe therein.
