Membranes Becoming Treatment Method of Choice for Large Scale Drinking Water Plants

Quality drinking water, virtually free of harmful contaminants such as parasites, bacteria and most viruses, is now a cost competitive alternative to other conventional forms of water treatment.
As a result, Thornton, Colo., Scottsdale, Ariz., and Mississauga (Peel Region), Ont., will all be future sites of membrane plants using ZENON‚s (TSX: ZEN and ZEN.A; OTC: ZNEVF and ZNEAF) proprietary technology.
The City of Thornton, Colo. needed to expand and upgrade the existing drinking water plant to service its community of more than 100,000 people. In addition to looking for a reliable, proven technology, the municipality had to consider how easily any new technology could be retrofitted into the existing plant.
The new system is expected to be complete by the spring of 2005 and will treat 50 million gallons of drinking water per day (189,000 m3/d).
The City of Scottsdale is currently paying the City of Phoenix to treat a portion of its drinking water, sourced from the Salt River Project. This is challenging surface water because it also contains levels of arsenic that can reach as high as 20 øg/l, double that of the recently revised US EPA limit of 10 øg/l. In addition to this, the City has limited space for building a new water treatment plant.
The new Chaparral Water Treatment Plant will be built on a 10-acre site. Once completed in the spring of 2005, it will be treating 30 million gallons of drinking water per day (114,000 m3/d).
In an effort to upgrade and expand a drinking water facility in the City of Mississauga, Ont., Regional Council for Peel Region recently approved the purchase of ZENON’s membrane technology for the Lakeview Water Treatment Plant. The expansion will add 80 million gallons per day (over 300 ML), summer capacity, of drinking water to the existing 148 million gallons per day (560 ML) currently being produced.
This expansion will constitute the largest ultrafiltration membrane installation for drinking water treatment in the world. The plant expansion is scheduled for completion in 2006.
