Pasteurized Milk Ordinance (PMO) Requirements For UV Inactivation

Pasteurized Milk Ordinance (PMO) specifies the equipment and processes required to produce Grade-A milk approved for interstate shipment. The PMO document is prepared by the National Conference on Interstate Milk Shipments (NCIMS) and is incorporated by reference into Federal specifications. The ordinance is a “grass-roots” consensus of current knowledge & experience, representing a practical & equitable milk sanitation standard for the nation.

PMO Requirements and UV

The PMO specifies that water for use in contact with milk in Grade-A plants must be pasteurized. Since 2011, Ultraviolet treatment has been approved to replace thermal pasteurization for this water, as long as certain criteria are met.

PMO requires that all water treatment technology for dairy plant usage must be fail-safe, ensuring that 100% of the water is fully treated. UV treatment equipment must initiate flow-diversion if the UV dose falls below target, or if the system operation is otherwise compromised.

All Aquafine SwiftBeverage PMO systems have been designed to meet the diversion requirement, to regulate flow and to have the required sensor per lamp to ensure full compliance with the PMO.

Why UV Instead of Pasteurization?

• Significant energy savings

• High efficiency and performance

• Provides diversion under alarm conditions

• High system stability and low downtime

• Installed and operating at large dairy facilities

• Low maintenance cost
