French to English Science Medical: Pharmaceuticals

This term comes from a document on vaccin production. The specific passage involves the water used for production. The term "boucle momu" is in italics and I am not sure whether this phrase has a special meaning or if "momu" is a French word at all.

"Utilities (eaux/vapeur)...
Eau Purifiée ***Boucle Momu***
Bonne maîtrise de la qualité de l'eau de la boucle.

Eau pour injection
La qualité de l'eau de la boucle et de sa production est maîtrisée...

Any insight would be appreciated, thanks.
