This slide presentation outlines a case study at the Manitowoc (Wisconsin) Public Utilities (MPU) concerning the design of two large-scale membrane treatment plants. The presentation outline includes: Background and History; Existing Membrane Facility at MPU; New Membrane Facility; and, Improvements Over Past Facilities. Conclusions indicate that: new 25 mgd submerged MF plant in Manitowoc will provide existing and projected water needs for newly formed Central Brown County Water Authority; existing microfiltration (MF) facility state-of-the-art in 1999, breaking new ground in terms of cost and schedule; rapid changes in industry over last 7 years have allowed for drastic improvements in cost, space requirements, and operability at new facility; and, as the industry continues to develop it provides new opportunities for utilities considering the use of membrane technologies.
