1. An apparatus for reducing or deterring biological contamination in an enclosed space, comprising:
- a housing defining a chamber including a first fluid aperture in communication with a source of biologically contaminated fluid and a second fluid aperture in communication with a destination;
a reservoir including an inlet and an outlet in fluid communication with said chamber and arranged such that a partial portion of a fluid flow from said source of biologically contaminated fluid is directed through said inlet to said reservoir and back through said outlet to said chamber;
said reservoir comprising a conduit extending from a first end proximal to the source of biologically contaminated fluid to a second end distal to said source of biologically contaminated fluid, said first end comprising said inlet for receiving said partial portion and said conduit delivering said partial portion to said second end;
said second end comprising means for diverting said partial flow from said conduit in a direction transverse to said conduit and into an interior of said reservoir, said interior of said reservoir containing a barrier chemical and defining a path for flowing said partial portion through said interior in a direction substantially opposite to its flow in said conduit, in contact with said barrier chemical, and to said outlet; and
said barrier chemical releasing into said partial portion of said fluid flow passing through said reservoir, so that said partial portion of said fluid flow returning back to said chamber contains a quantity of barrier chemical sufficient to reduce or deter said biological contamination in said enclosed space.

1. An apparatus for reducing or deterring biological contamination in an enclosed space, comprising:
-
a housing defining a chamber including a first fluid aperture in communication with a source of biologically contaminated fluid and a second fluid aperture in communication with a destination; a reservoir including an inlet and an outlet in fluid communication with said chamber and arranged such that a partial portion of a fluid flow from said source of biologically contaminated fluid is directed through said inlet to said reservoir and back through said outlet to said chamber; said reservoir comprising a conduit extending from a first end proximal to the source of biologically contaminated fluid to a second end distal to said source of biologically contaminated fluid, said first end comprising said inlet for receiving said partial portion and said conduit delivering said partial portion to said second end;
said second end comprising means for diverting said partial flow from said conduit in a direction transverse to said conduit and into an interior of said reservoir, said interior of said reservoir containing a barrier chemical and defining a path for flowing said partial portion through said interior in a direction substantially opposite to its flow in said conduit, in contact with said barrier chemical, and to said outlet; andsaid barrier chemical releasing into said partial portion of said fluid flow passing through said reservoir, so that said partial portion of said fluid flow returning back to said chamber contains a quantity of barrier chemical sufficient to reduce or deter said biological contamination in said enclosed space. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. A method for reducing biological contamination in an enclosed space, comprising the steps of:
-
providing a housing defining a chamber including a first fluid aperture in communication with a source of untreated fluid and a second fluid aperture in communication with a destination; providing a reservoir including an inlet and an outlet in fluid communication with said chamber and arranged such that at least a partial portion of a fluid flow from said source of untreated fluid is directed through said inlet to said reservoir and back through said outlet to said chamber; said reservoir comprising a conduit extending from a first end proximal to the source of untreated fluid to a second end distal to said source of untreated fluid, said first end comprising said inlet for receiving said partial portion, delivering said partial portion through said conduit to said second end and then through means at said second end for diverting said partial flow from said conduit in a direction transverse to said conduit and into an interior of said reservoir, said interior of said reservoir containing a barrier chemical and defining a path for flowing said partial portion through said interior in a direction substantially opposite to its flow in said conduit, in contact with said barrier chemical, and to said outlet; and releasing said barrier chemical into said partial portion of said fluid flow passing through said reservoir, so that said partial portion of said fluid flow returning back to said chamber contains a quantity of barrier chemical sufficient to reduce biological contamination in said enclosed space. - View Dependent Claims (14, 15, 16)

17. A method of deterring biological contamination in an enclosed space, comprising the steps of:
-
providing a housing defining a chamber including a first fluid aperture in communication with a source of biologically contaminated fluid and a second fluid aperture in communication with a destination; providing a reservoir including an inlet and an outlet in fluid communication with said chamber and arranged such that at least a partial portion of a fluid flow from said source of biologically contaminated fluid is directed through said inlet to said reservoir and back through said outlet to said chamber; said reservoir comprising a conduit extending from a first end proximal to the source of biologically contaminated fluid to a second end distal to said source of biologically contaminated fluid, said first end comprising said inlet for receiving said partial portion, delivering said partial portion through said conduit to said second end and then through means at said second end for diverting said partial flow from said conduit in a direction transverse to said conduit and into an interior of said reservoir, said interior of said reservoir containing a barrier chemical and defining a path for flowing said partial portion through said interior in a direction substantially opposite to its flow in said conduit, in contact with said barrier chemical, and to said outlet; and releasing said barrier chemical into said partial portion of said fluid flow passing through said reservoir, so that said partial portion of said fluid flow returning back to said chamber contains a quantity of barrier chemical sufficient to reduce or deter said biological contamination in said enclosed space. - View Dependent Claims (18, 19, 20)
