Brindisi Sud

Brindisi Sud (Federico II) is a coal-fired power plant that belongs to ENEL. It is located in the southern part of Italy. In the frame of the project, a new membrane test facility will be integrated in the power plant to recover water from waste streams coming from the flue gas desulphurization unit.


The Federico II power plant has a nominal capacity of 2640 MWe and comprises four coal-fired units. The first unit was commissioned in 1991, the last in 1993. All four units are equipped with wet flue gas desulphurization systems (FGD) for SO2-abatement. Currently, the waste waters coming from such units are pre-treated and recovered through a thermal evaporative process following the zero-liquid-discharge policy (ZLD). However, such kind of systems are costly.

The use of membranes could significantly reduce the costs and the complexity of the system. In the frame of MATCHING, a novel membrane-based facility will be built and integrated in the power plant to demonstrate the process up to a significant industrial size (e.g 10-20 mc/day).

The facility will include pilot units of both membrane distillation modules and pressure driven membranes (MF, UF, NF (micro, ultra, nano filtration) or RO (reverse osmosis)).
