Stora Enso is one the world's largest pulp and paper company. Located in Nova Scotia on the east coast of Canada, the Port Hawkesbury mill has been in operation since 1962. Today its capacity is 190,000 tonnes of newsprint on PM1 and 360,000 tonnes of supercalendered (SC-A+ and SC-A) paper on PM2. Since the start-up of PM2 in 1998, the SC paper machine has reached several world daily speed records at 1600, 1700 and 1800 meters a minute. Approximately 85% of our paper production goes to the United States and the remainder within Canada.

At Port Hawkesbury, Stora Enso needed to quadruple the capacity of its water treatment plant while achieving higher quality water, eliminating the use of untreated water in its two paper machines and related processes. Says Seldon McKenzie, Stora Enso's manager of development projects, "A consistent supply of high purity water is critical to our paper making process. We are expecting the state of the art water treatment technology offered by John Meunier Inc. to help us improve upon our processes and efficiencies, ultimately resulting in higher production of high quality paper."

After conducting several pilot studies, John Meunier Inc. has supplied a turnkey for a new process water treatment system consisting of two Actiflo® Ballasted Clarification units and six Dusenflo® Gravity Filters, chemical preparation and metering systems, distribution pumping, instrumentation and control, piping and valves, installation, startup and training. John Meunier Inc. determined that the Actiflo® and Dusenflo® technologies are best able to retrofit the paper producer's existing water treatment plant. The solution provided to Stora Enso will not only reduce operating time and maintenance costs but will also ensure that the paper quality is unaffected by turbidity, iron, aluminum and manganese contained in the raw water. The plant, designed to produce 60,000 cubic meters per day of treated water, was commissioned in summer of 2002.
