RE: Odor elimination at a chamois facility



Tammy,

Could an odorless mineral oil be used in place of the cod liver oil ?  Or
perhaps another plant derived oil that is less objectionable ?  If you can't
change the process, there are several companies that market essential oil
products that absorb and control odors. They can be injected into the
discharge stack for odor control.  Ecosorb has a good website with lots of
product info.

How is the cod liver oil applied/removed ?  If it is heated or sprayed, the
odor may be due to oil droplets.  A high efficiency mist eliminator would
capture most of this.  If it truly is a vapor, then a biofilter would be
effective. Commercial unit are available if you have limited space or one
can be constructed from an open plot of land.  Its sort of a leach field for
vapors.

Hope this helps,
