MF/UF Membrane Replacement

This presentation discusses indicators for microfiltration (MF) and ultrafiltration (UF) membrane module replacement, presents replacement case studies, provides a summary of lessons learned, and highlights recent developments in system design that allow for increased flexibility during module replacement. The three case studies include a discussion of options for membrane module replacement at both pressure and submerged membrane facilities. Lessons learned include challenges related to warranty claims, financial implications of pre-negotiated long term pricing, and understanding warranty issues. The presentation concludes with a discussion on the development of standard original equipment manufacturer (OEM) products that allow for module interchangeability.
