UV technology for PMO-compliant Pasteurized Equivalent Water

Ultraviolet processing can replace thermal pasteurization for PMO-compliant pasteurized equivalent water

The Pasteurized Milk Ordinance (PMO) is an important guidance document for the US dairy industry. The 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 Treatment

The Pasteurized Milk Ordinance 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, if certain criteria are met.

The Pasteurized Milk Ordinance 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.

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
