Advanced Water and Wastewater Treatment

Tertiary Membrane Treatment of Secondary Effluent

We are currently investigating the application of tertiary immersed membranes in conjunction with chemical coagulation for the removal of phosphorus and endocrine disruptors from the secondary effluent at the City of Guelph Wastewater Treatment Plant. This project if funded by the Canadian Water Network with inkind contributions from GE Water - Zenon Environmental and the City of Guelph. This project is part of larger national project that involves other researchers from the School of Engineering (Dr. Hongde Zhou) and four other universities; UBC, U. Manitoba, Ryerson, and Ecole Polytechnique.

MSc. Candidate, Joel Citulski successfully defended his thesis on this project in January 2008. Joel is currently pursuing his PhD research in this area.

Monitoring Membrane Integrity

Membrane integrity monitoring is essential in ensuring that the membrane is intact and capable of removing pathogens in water and wastewater. We have conducted considerable amount of work in this area including improvement of the pressure decay test, development of correlation between the pressure decay test and microbial removal, particle counters for indirect membrane integrity monitoring, application of fluorescent beads for membrane integrity testing and the impact of temperature on membrane integrity tests.
