ENVIROCELL 2-DAY TRAINING SEMINAR

WASTEWATER TREATMENT AT PAPER MILLS

This two day seminar is aimed at anyone involved in the design and operation
of treatment plants from operators to production/technical staff, including
suppliers of treatment plant and chemicals. Whilst the legislative background
and technical theory are covered, the emphasis is on practical aspects with
a view to improving basic understanding and overall plant performance.
The notes accompanying this seminar are continually updated, providing a
comprehensive document for reference purposes.
