This powerpoint presentation begins by stating the regulatory drivers formembranes and ultraviolet (UV). Topics covered in the presentation include: regulatory requirements for design;monitoring requirements;operational challenges;Case 1: Synergistic Surface Water Plant Design; and,Case 2: High Recovery Plant Design. Project summary includes: membranes and UV represent best availabletechnologies to comply with LT2 requirements;although they provide the same benefit, theircombined use in a WTP provides real synergiesin reducing maintenance requirements for bothmembrane and UV systems;designing UV for higher doses allows potentialfor membrane system operation at lower LRVs;using dedicated UV on secondary membranepermeate provides disinfection equivalency; and,utilities should work with State regulatoryagencies to discuss implementation. Includes tables, figures.
