Microfiltration System – Bacteria Removal (Dairy Applications)

General Information:
– Manufacturer: Tetra Pak
– Model: Tetra Alcross M
– Year: 2005
– Automation: Fully automatic
– Application: Bacteria extraction / microfiltration for dairy products

System Overview:

The Tetra Alcross M is an industrial-grade microfiltration system designed for efficient bacterial and spore reduction in dairy processing, particularly in skim milk applications.

Engineered for continuous production, the system utilizes high-performance ceramic double-layer membranes, enabling reliable separation performance and consistent product quality.

This technology is widely used in ESL milk production and other high-hygiene dairy processes, where stable filtration performance and sanitary design are critical. The robust construction and proven reliability of the Tetra Alcross platform make it suitable for integration into modern dairy processing lines.
