Sofidel starts a new wastewater treatment plant at Delicarta Paper Mill in Italy

Sofidel has recently started a new wastewater purification plant for reducing the amount of clean water extracted from the groundwater table at Delicarta Paper Mill, in Porcari (Italy).
The technology used is currently one of the best and most innovative available and makes it possible to recover up to 75% of wastewater, saving 350,000 m3 fresh water annually.
The process involves three phases. In the first phase the wastewater undergoes a biological process. In the second, for the solid-liquid separation, it undergoes a ultrafiltration section (this treatment takes the name of the MBR -Membrane Biological Reactor). The third and last phase, aiming at eliminating the remaining salt fraction, consists of a reverse osmosis system.
The technical partner is Degremont, with General Electric handling the MBR (Membrane Biological Reactor) aspect of the process.
The overall investment for the implementation of the project, the first in the paper tissue sector, was 3 million Euros.
