About Junlebao Dairy Group
Junlebao Dairy Group, founded in 1995, has established itself as a cornerstone of China's dairy industry. Committed to providing healthy, nutritious, and safe dairy products, the company's extensive portfolio includes infant milk powder, low-temperature yogurt, low-temperature milk, ambient liquid milk, and animal husbandry.
With 21 production plants and 17 modern large farms across Hebei, Henan, Jiangsu, and Jilin provinces, Junlebao's operations are massive and complex. Protecting the water infrastructure across such a vast network is critical to ensuring product quality and operational efficiency. The group turned to Vulcan to address scaling issues in cooling and process water systems at three key Hebei facilities: Wei County, Baoding, and Cangzhou.

The Challenge: Scale in Critical Dairy Production Systems
In dairy processing, water quality is paramount. Mineral scale can compromise cooling efficiency, clog intricate piping, and threaten the reliability of reverse osmosis systems used for water reuse. Junlebao faced several challenges across its factories:
- Cooling Water Circulation: Scale buildup reducing heat exchange efficiency in critical cooling towers.
- Chilled Water Systems: Potential for blockages and efficiency loss in lines serving production areas.
- RO Concentrate Water Reuse: Protecting expensive reverse osmosis membranes from scaling in a Cangzhou factory's water recycling initiative.
- Operational Reliability: The need for a chemical-free solution to avoid contaminating sensitive dairy processes.
