Looking down from the top of the FERMENTER,
(photo to the right) you can see some of the various dyes, surfactants and
perfume supplies added to certain products.  

The view to the left shows some of the containers
used in packaging finished product. 
After a liquid product is cultured, excess
liquid volume and nutrients are often removed by recirculating the product
through the ULTRA-FILTRATION SYSTEM shown to the right. Bacteria are retained
in the circulation loop, while excess nutrients and water go through the
cylindrical filter and can be drained off. The volume can be decreased to
as little as one tenth of the original volume.

 

After a product is finished and leaves
this system, a chemical cycle involving a hydroxide soak, is used to clean
the system, followed by treatment with hypochlorite and subsequent pH reduction
to 2.5. 

 

To prepare the filter for reuse, the acid
is neutralized and the system is flushed with distilled water.
