VREUGDENHIL DAIRY FOODS factory in Joure (The Netherlands):
Vreugdenhill dairy foods is present on the dairy market since 1954 and is the largest producer of whole cream milk powder in Europe. Three factories in the Netherlands are collecting and processing the milk of more than 900 farms to produce powder milk for the food industry and for millions of consumers worldwide. For their factory in Joure (NL), we installed OXAQUA RW CL system to treat water flows varying from 1m3/hour up to 25m3/hour on a recirculating loop. |

This treated, and therefore sterilized water, is being used for the cooling water in the heat exchangers and thus keeping the cooling water (for the injection mold machine where the plastic milk bottles are being produced) free from any bacterial contamination.
The same factory uses BlueSense’s in-line OXAQUA system to sanitize the water, used to prevent dust explosions in the dry milk powder towers.

Vreugdenhil’s case study: detailed here by Sybren Abma Technical Dept. Manager
• Cooling water treatment
• Hydrofores
• Make up water quality :
- Ph : 7.7
- Cl- : 34mg/l
- Temperature : 11°C
The laboratories are sampling the water of the factory every week on Thursday, testing for bacteria, and reporting on Monday. Levels have to be below 100 cfu per ml. (drinking water standards) with all water treated by our equipment. Free chlorine residual has to be in a range between 0.4 and 0.6 ppm.

Oxaqua RW CL Installed
In order to keep the free chlorine levels in the piping, where water is not flowing continuously, Vreugdenhil uses fully automatic open (electric) valves, 4 times a day, to get chlorinated water to the end of the tap. The water network is made of Stainless Steel 316. The flushing lasts for 5 minutes.
The temperature of the water in the cooling system can easily reach 40°C, creating the ideal conditions for bacterial blooming. Therefore, a regular flushing of the system is done.
The fresh water is passing through the OXAQUA system in order to avoid any risk of external contamination.
As a result, the bacterial count in our process systems is less than 1CFU, which is compliant to our manufacturing standards.
