Ozone improves ceramic membrane use for wastewater reclamation
Ceramic membranes have been used in the industrial production of beer, wine and cheese. One of the reasons for this use is the narrow pore size distribution, where careful separation of different size compounds can be achieved. Outside of Japan, the use of ceramic membranes has been almost non-existent for municipal drinking-water systems. The slow adoption of this technology is largely the result of a perception by many that the costs are significantly higher. While the capital costs may be higher, the whole life cycle costs may not be, due to extended membrane life and more reliable operation. Most water reuse today takes the form of indirect potable reuse. These schemes frequently consist of several steps including physical and chemical disinfection and advanced oxidation. They have the disadvantage of high cost and often poor membrane fluxes due to the nature of the wastewater being treated. The study outlined in this article is preliminary, but shows that ozone in conjunction with ceramic membranes for water-reuse applications has many advantages when disinfection and advanced oxidation is required. As opposed to polymeric membrane systems that cannot tolerate ozone, ceramic membranes in conjunction with ozone can achieve multiple key objectives in one step. This article appeared in the May/June issue of D&WR magazine.

This article will start by considering general advantages of membrane use together with the reference and experience position, and then examine the particular benefits of PESU in terms of treated water quality. The final sections include a review of membrane pretreatment costs and environmental impact in comparison with conventional pretreatment technology. The second article, to be published at the beginning of 2010, will consider the advantages in using PESU membranes in municipal water applications.

San Francisco study proves impaired source still feasible
The Marin Municipal Water District (MMWD), near San Francisco, USA, has been exploring seawater desalination to provide a drought-proof supplement to its over-extended water supply. Desalination of San Francisco Bay water presents challenges for pretreatment due to the frequent changes in water quality from the ebb and flow of the tides and winds, seasonal changes in the flows of two major rivers (Sacramento and San Joaquin), and impacts from stormwater and industrial discharges. It also presents technical and sociological challenges to convince customers that high quality drinking water can be produced from an impaired water source. A 12-month desalination pilot program was carried out to achieve the following main objectives: Test different pretreatment processes and membrane performance to determine which ones perform best to process SF Bay source water. Perform studies to address environmental concerns to facilitate permit applications and support an environmental impact report. Demonstrate that SWRO can reliably produce high-quality drinking water through comprehensive water-quality testing, tours and public outreach This article appeared in D&WR magazine's August/September 2008 issue.
