Membrane filters, such as those currently used in some home water purification systems, might someday be used on a large scale to remove contaminants and organic compounds that affect the purity of municipal water supplies, according to UH researchers. Shankar Chellam, assistant professor of civil and environmental engineering, discusses his reseach in the latest edition of the 'Images' audio Web cast program.

Understanding how such filters interact with various contaminants will help engineers devise more efficient filters, says Chellam. "Ultimately, the cost of membrane technology will go down and make it more feasible to be used for large-scale implementation," he says.
