Issues with Hengyang Thermal Power plant’s existing UF system compromised its ability to reliably meet the demand for steam generation – particularly during peak season, when demand was higher and more variable:

  • The fouling of polymeric UF (PUF) membranes resulted in cleaning one-to-two times a month, each requiring 12 hours offline and significant labor. The damage from such extensive fouling was often irreversible.
  • Fiber breakage started within one year of PUF installation, leading to frequent system shutdowns, with each labor-intensive repair requiring a full week offline.
  • Permeate quality did not meet reverse osmosis (RO) system requirements, which necessitated monthly cleanings and shortened the RO membranes’ life.
