Notes on Membrane Cleaning

  • Never mix different cleaning agents! Mixing will neutralize the cleaning solutions, minimize cleaning efficiency and damage the membrane surface.
  • Do not clean the membrane sheet by hand or with any soft tools that may impair the filtration performance and reduce the desalination capacity of the membrane material.
  • Deionized water shall be used for cleaning and storage to ensure optimal cleaning performance.

 

Warranty Period

The company warrants the performance of membrane elements for three 3 years. The three-year warranty period shall commence on the earliest of the following dates:

  • The date when the reverse osmosis system is put into operation;
  • Six 6 months from the date the membrane elements are shipped from the manufacturing site;
  • Three 3 months after the membrane elements are shipped from Guangzhou / Shanghai, China to Taiwan of China, Japan, South Korea, Thailand, India, Malaysia, the United States and other designated locations in China.
