Effluent treatment course - module III -Figueira da Foz


Effluent treatment course - module III -Figueira da Foz


Effluent treatment and water use management is one of the permanent chalenges of the pulp and paper industry which on today’s context is of the outmost importance due to:

Increased and new compliance requirements on emission limit values but also on monitoring and scope
Inreased pressure on water resources related with availability and reduced impact on recipient media

On the other hand, the need to keep update the pulp and paper technicians  in such a specific subject is one of the main reasons for this course.


The course have an modular structure with the following objectives:

1. Review and systematize the basic knowledge of today’s biological treatment
2. Acquire the knowledge related with technological aspects of the biological treatment processes and equipment applied in the pulp and paper industry
3. Supply troubleshooting tools;
4. Acquire the knowledge related with new and modified biological treatment processes revamp possibilities from traditional activated sludge systems

5. Evaluate advanced treatment system to remove additionally pollutants or specific parameters for stringiest compliance and integrated on minimal water use context, promoting circularity

Module III has as objective the item 5.
