Performance Testing of a 380 ML/d Retrofitted Membrane/UV Oxidation WTP

This article presents the results at the Lorne Park Water Treatment Plant (WTP) in Mississauga, Ontario, Canada of the performance testing that was conducted and lessons learned for future membrane performance testing. Once the Lorne Park WTP was fully commissioned, the membrane system had to be tested in accordance with the pre-selection document. This was completed over a six month period with two of the sixteen membrane trains operating in supervisory mode at maximum design capacity of 31.7 ML/d per train. Operating data and lessons learned are shared in this paper.
