Ann: Fluence signs another multi-unit Aspiral order in China, page-15

Its not just the physical infrastructure issues.

"This IFAS process creates an environment where the biofilm is mainly comprised of autotrophic
nitrifying bacteria in an oxygen rich environment created at the membrane wall, while
heterotrophic bacteria oxidize the BOD, primarily by denitrification."

So I wonder what temperature the water needs to be to maintain a biofilm?
Clearly a pre-stage would need to get the water up to a temperature suitable to circulate through the Aspiral units and still keep the environment condusive to good biofilm health.

They are obviously confident they have it worked out.
