Mist & contaminants be gone at SAICA Champblain. But how? Article by Kadant / M-clean
SAICA Champblain, France, has achieved a forming section breakthrough-mist elimination and fewer showers at the wet end made possible with the Kadant M-clean™ system. Combined with M-clean units to remove contaminants from dryer fabrics, SAICA now enjoys major water and energy savings, as well as greater ease to increase productivity.

ccording to Pierre Henri Brouty, project engineer and innovations team leader with SAICA Champblain, “Removing forward showers from our Bel Baie Sup MAP 60 forming section allows us to sharply reduce habitual mist. With this M-clean unit we use only 7 m3/day of water, compared to 500 m3/day for this task. We start up in 3-4 hours less time.” Brouty notes that their pioneering effort at the forming section is a natural progression from the cleanliness already achieved with M-clean units at the dryer sections of both paper machines, where runnability is up.

Adds Brouty, “Better work conditions and safety are important gains for mill operators and workers. The value of eliminating mist at the wet end cannot be under estimated.”
FORMING CLEANLINESS — HOW IT HAPPENS The M-clean unit traverses the forming section, using high-pressure water in combination with a robust evacuation and air knife system. By cleaning on top and underneath, this opens the pores of the forming fabric. Contaminants and water are then separated in a cyclone. Says Ludovic Veyre, applications engineer with Kadant Lamort, “SAICA’s forming section innovation is a major technological breakthrough for the papermaking process. The extraction of contaminants for a 8,700 mm fabric width wit-
