Industrial Context

A process control course was elaborated around the specific regional (industrial) context in which UQAR has an important mission of regional development. A multidisciplinary approach is used, integrating notions from various fields of engineering (electrical, mechanical, chemical and civil engineering) through theme examples such as wastewater treatment, pulp and paper making, mining and metallurgical extraction (mineral grinding). Laboratory activities on such processes are realized using a simulation software specifically designed for process control education. The small size of the groups at UQAR also allows to employ innovative strategies on how to run the activities and to evaluate the students. One laboratory on a real physical system (electrical motor) was also part of the course, to balance between the advantages of the software and the more “hands-on” laboratories. General feedback and comparative appreciation from students is then presented, followed by overall conclusions

Removal Efficiencies

The effluent from biochemical treatment of pulp and paper making wastewater treated by heterogeneous Fenton fluid-bed reactor was evaluated. The results showed that in the condition of COD 350mg/L, and the optimum conditions of pH at 3, FeSO4 2.5mmol/L, H2O2 3.4mmol/L, and reaction time at 20 minutes, the removal efficiencies of COD and color are more than 85% and 90%, respectively. The best drug dosing ratio of heterogeneous Fenton fluid-bed reactor has positive relations with COD of raw water, and the mole ratio of COD, FeSO4, and H2O2 is 6.4:0.74:1.
