Levure Fleischmann, a yeast production plant, is located in LaSalle near Montreal. The yeast is a micro-organism found in the ground, on plants and in the air. It serves as catalyst in the fermentation process, necessary for bread making.

There are several yeast varieties used for fermenting dough, beer, wine and others. The variety used by Fleischmann for the fermentation of bread dough is saccharomyces cerevisiae.

Levure Fleischmann had a drinking water production plant to feed the yeast production line. However, the existing equipment was now outdated toward the produced water quality and quantity as well.

On several occasions, Levure Fleischmann had to buy its water from the town of Montreal in order to fill their needs. The costs generated by the purchase of water and the poor quality of the produced water have brought Levure Fleischmann to consider the rehabilitation of their own drinking water plant.  

John Meunier Inc. proposed the installation of two (2) ACP-400 Actiflo^® packaged clarification units in the existing clarifier. By this mean, we increased the drinking water production capacity from 3,500 m3/d to 8,000 m3/d.

Concerning the filtration, we replaced the four (4) existing wood filters by two model DUS-400 Dusenflo^® packaged filtration units. We also replaced the dosage systems for chemicals and the plant controls. JMI did the detailed engineering for this project, the treatment units manufacturing, the piping and installation of this equipment. The achievement of these projects allows continuous conformity to process water production standards and to insure drinkable water production capacity for many years.
