Pasteurized Equivalent Water Treatment At Tnuva Ba'Emek, Israel

In the heart of Israel’s Jezreel Valley, Ba’emek Advanced Technologies—part of the Tnuva Group—faced a critical challenge: how to sustainably reuse water extracted from whey during dairy processing without compromising safety or quality. With 75% of whey volume becoming COW water, traditional heat pasteurization was costly and energy-intensive. The solution? Atlantium Technologies’ HOD™ UV disinfection system.

In 2012, Ba’emek installed two Atlantium RZ Series units to disinfect reverse osmosis (RO) permeate, achieving FDA-compliant pasteurized water standards. This innovative, non-thermal method leverages Total Internal Reflection (TIR) to deliver superior microbial inactivation, even in high-load summer conditions. The result: consistent production of high-quality process water for cleaning and operations, without risking product integrity.

The payoff has been impressive—dramatically improved microbiological performance, operational efficiency, and annual energy savings of $162,000. By replacing heat-based systems with cutting-edge UV treatment, Ba’emek not only secured water safety but also embraced a greener, more cost-effective future.
