Comment and assessment
• The simple filter F-2 is not of a design that will
provide sterile compressed air to the process. A
HEPA filter could be fitted to address this problem,
although this would not be a minor modification.
• Large amounts of compressed air are required for
each production cycle (see 2.6) and the risk of contamination
(failure) of any given batch is increased
if process air is not sterilized.
• The low pressure compressor set is of standard
reciprocating design and will not provide “oil-free”
air. Oil-free air compressors are often specified in
fermentation installations though in this particular
concept (i.e. the production of “fire-and-forget” BW
agents), it is unlikely to be a critical factor.
• These trailers were not designed with anaerobic fermentations
in mind. Although it would be possible
(but extremely inconvenient) to connect nitrogen
cylinders to the sparge system, it is noteworthy that
no provision has been made on the trailers for the
