The present invention pertains to the fields of environmental engineering and microbiology, being related to energy conservation and waste management. More specifically, the present invention provides an equipment and a method for the in-situ and ex-situ modulation of microbial consortia useful in liquid and semi-solid effluent and solid waste treatment systems, for removing and/or reusing undesirable organic or inorganic loads. The equipment of the invention consists in a main culture tank or liquid body provided with an ex-situ subsystem for modulating microbial consortia for subsequent or concomitant introduction into the main culture tank or reactor or into the liquid body. In one embodiment, the in-situ and ex-situ method of the invention is implemented in a culture equipment with controlled conditions for introducing the micro-organism-enriched material into the effluent or solid waste to be treated, in the form of a preliminary and/or simultaneous culture. In another embodiment, the ex-situ subsystem of the invention comprises a device for forming gas/air bubbles in a liquid suitable for applying a shearing force to the micro-organisms present in the system, and also useful for modulating the microbial consortia in a main culture tank or liquid body. The invention substantially enhances the performance of effluent treatment systems, increasing the capacity of already installed units and/or reducing the cost of installation of new units; it allows the use of effluents as a biomass for the biotransformation and generation of products of economic interest. |
