Hollow-fiber 775-square-foot ultrafiltration modules from Toray Membrane USA contain high-strength PVDF fibers. The fibers can operate in high fluxes with reduced fouling and high reliability. When used with reverse osmosis elements at water reclamation plants, they validate the feasibility of indirect potable reuse. Systems have recorded greater than 4-log reduction in somatic bacteriophage through a combination of chloramines and ultrafiltration. 858/218-2390; www.toraywater.com.
