The rehabilitation project for Baia Mare Water Treatment Plant has reconsidered the entire initial treatment process, introducing modern procedures and integrating a substantial part of the existing ones in order to obtain a treatment system duly adapted to the raw water quality and to the treated water requirements in accordance with Law 458/2002 and EC Directive 98/83/EC.
The main rehabilitation works of the plant refer to:
- Introducing a new settlement step in the technological process;
- Facilities for sludge treatment;
- Introducing a control, automation and data system.
