| Abstract |
In the current frame of the circular economy, evaluation of the valorization potential of saline-type wastewater is an objective, as this type of effluent represents approximately 9% of all the produced wastewater in the world. Apart from the evident water recovery for reuse, accomplishing valorization of the organic and inorganic pollutant compounds is also explored. Obtaining products, such as volatile fatty acids (VFA), exopolymers (EPS) or polyhydroxyalkanoates (PHA) among others, from organic carbon compounds, entails the development of innovative processes, which must produce treated effluents suitable for discharge or reuse. In addition, the organic compounds can be anaerobically converted to methane-containing biogas to be used as an energy source. Concerning the inorganic fraction, either nutrients or salts recovery offers an opportunity to extract some economic value from these effluents. Furthermore, there are industrial processes admitting relatively high saline effluents in their units, such as some refrigeration towers, that allow for direct water reuse. |
