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.

• 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 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.

De Boer Poultry Farm
Drachtstercompagnie, Friesland, The Netherlands Mezutec Distribution for BlueSense™ The farm has 75,000 "Ster kuieken" (= high quality label chickens in The Netherlands) under 3 sheds. The animals arrive as day-old chicks and are commercialized on the Dutch domestic market after 56 days. Drinking water comes from a 80 meters deep well and is softened and disinfected before being distributed. Average daily consumption varies from 20,000 litres to 25,000 litres a day along the poultry growth cycle. |

Oxaqua 1 in-line system
De Boer Chicken Farm

Out of 3 livestock buildings, one was equipped with OXAQUA 1, and the other 2 were not. Being “plug and play”, our material was easily retrofitted downstream the existing line.
Microbiological analysis of the water fed to the chicken, treated by BlueSense™ equipment, shows significant improvement compared to the unequipped lines :
Water being one of the key vectors for illnesses, using BlueSense™ OXAQUA unit will result in less consumption of antibiotics, healthier poultries and a better yield per batch is expected. "Well-purified water is vitally important to our business, my savings on tap water is an important reason for me to use my own spring water", explains the grower. "It is very important that we can be confident that the treatment is 100% guaranteed... The personal approach and the tailor-made solutions fit in perfectly with our way of working, so the choice was made quickly". |
Installation principle :

is lower than 20 ppm, a brine production

Vroege Milking Farm
Dalen, Friesland, The Netherlands
Dalen, Friesland, The Netherlands
|
The Vroege farm has 1100 Holstein cows under 2 stables (1 x 750 cows and 1 x 350 cows).
The farm produces about 10 million litres of milk per year. The drinking water network was equipped in 2015 with an OxAgri XS, to ensure the production of 0,250 m3 per day of ECA water at a concentration of 4,000ppm of free chlorine, or 1 kg / day of pure disinfectant. |

" Good water is as important as cattle feed [...] We have the feeling that the cows are more healthy and that the use of antibiotic is low. says Wilco. " |
|
Drinking water :
Water comes from a 40 meters deep well and is de-ironed and disinfected with ECA water before being distributed to the animals. The average water daily consumption varies between 100-120 litres per day per cow. The farm reaches an overall consumption of over 120 000 litres per day (including the calves). The free chlorine solution is stored in a tank and dosed into the network to disinfect the water supplied to the cows. The ECA water not only protects the animal from any bacterial contamination, but also ensures the disinfection of the piping network, the water tanks and reduces the growth of the biofilm. Water is one of the key vectors for illnesses, using BlueSense™ OxAgri system will result in less consumption of antibiotics, healthier cows and a higher milk yield from the flock. |
|
Clean in Place :
In the Vroege farm, the ECA water produced is also used to clean the milking parlors hard surfaces and avoid any bacteria development. |
|
Disease Prevention :
The hooves of the cows are also sprayed with ECA water on a regular basis to keep them free of digital dermatitis. |
|
OxAGri Working principle :
- Filtered water is used to prepare a saturated brine (Salt + Water). - Water is circulated through the electrolysis cell to produce up to 6,000 ppm free chlorine solution. - It is then transferred into the ECA Water tank (Electro-Chemically Activated). - A new brine is produced, softener is regenerated and a new batch is produced. |

Vernooy VOF Peony and Hosta Farm
De Zilk, The Netherlands Vernooy VOF has more than 30 years of experience in supplying perennial flowers and plants for the horticulture business.
It specializes in breeding and production of starting material for hostas and peonies. The farm consists of approximately 80 species and varieties of hostas and as many peonies covering more than 20 hectares. |
Vernooy Tunnel Greenhouses

|
By using OxAgri ECA water (Electro Chemical Activated), Vernooy strive to create a more sustainable and environmental friendly way of growing their flowers, reducing the use of chemical products. Now that formaldehyde is banned, Vernooy chose our system to kill bacteria such as botrytis, and also mold such as fusarium and of course viruses like HVX and tabaksratelvirus from their growing material.
