Modernisation of Effluent Treatment Plant

CMPC is an international packaging and paper group and fully integrated across the packaging and paper value chain - from managing forests and producing pulp, paper and compound plastics, to developing effective and innovative industrial and consumer packaging solutions.

During an audit of the CMPC Puente Alto Effluent Treatment Plant, ÅF worked closely with its partner in project management and in the execution of the consulting and evaluation work.

Together with CMPC, our work included detailed analysis of plant performance and evaluation of corrective measures. Also, the work involved general consultancy in different aspects of the operation processes.

To meet CMPC's needs and optimize its operations, our ambition was to work closely with the client throughout the process. The most important part of that work always involves listening and asking questions to understand the client's challenges and ambitions.

Our work included a detailed analysis of history data and an evaluation of performance at future production levels. The report also included a status evaluation, determination of key performance data and list of recommended actions.

The audit focused on the following items:

  • Assess demand for new primary clarifier
  • Efficient removal of coarse solids (plastics)
  • Secondary treatment optimisation
  • Sludge handling optimisation
  • Odour control principles
  • Suggestion for process instrumentation, control and monitoring.
