After 14 days: Lactating cow milk production improved, piglets reached higher body weights (7kg to 8kg). Scale and biofilms in old pipes dissolved, improving feeding behavior. Cows now produce 0.5L more milk per day. A German dairy farmer's detailed 4-week results with Vulcan.
Hubertus Fasselt is a dedicated animal farmer in Germany operating a mixed livestock farm with dairy cows, piglets, and fattening pigs. Like many farmers, he faced persistent challenges with water quality—scale buildup in pipes, biofilm contamination, and reduced water intake affecting animal health and productivity.
Before installing Vulcan, Fasselt had to flush his water lines every 4 weeks with air and water just to ensure his cows could get enough water through the pipes. Biofilms caused flank abscesses and ear necrosis. He needed a solution that would address these issues without adding chemicals to his animals' water supply.

"It was remarkable that the lactating cows were permanently drinking from the drinking trough."
14 Days
Lactating cow milk production improved
Piglets: 7kg → 8kg body weight

4-week pipe flushing eliminated. Biofilm on steel drinking trough dissolved. Flank abscesses reduced.
"I noticed that the drinking behavior of the animals improved promptly."
It was remarkable that the lactating cows were permanently drinking from the drinking trough.
Lactating cow milk production also improved, our piglets had higher body weights (before: 7 kg / now: 8 kg). Furthermore, we observed that scale and biofilms in old pipes for liquid feeding dissolved, leading to an improved feeding behavior of the fattened pigs.
Moreover, we used to have trouble with flank abscesses due to biofilms that were probably caused by bacteria discarding endotoxin. The biofilm on the high-alloyed steel drinking trough has also dissolved. This progressively improved with the use of the mineral descaler.
Before the Vulcan descaler, pipes had to be flushed out every 4 weeks with air and water to make sure the cows could get enough water through the pipes. We have now observed that this is no longer happening.
Cows are producing about 0.5 L more milk per day.
In February the following year, I occasionally started adding acids in the tubes (it is common practice to use acid products in farms holding pigs and turkeys) and started noticing that the positive effect of the mineral descaler water treatment mostly vanished. Furthermore, new biofilms built up in the pipes, which I could make visible by flushing the pipes. The animals began to show more flank abscesses and ear necrosis again. This improved again after flushing in the beginning of June.
Then, on 19 July, I installed the stronger electronic system. Since then, I have the feeling that the livestock has stabilized and has become more vital.

Hubertus Fasselt's detailed 4-week documentation provides irrefutable evidence: when water lines are clean and biofilm-free, animals drink more, gain weight faster, and produce more milk. When chemicals were reintroduced, the benefits vanished. When a stronger Vulcan system was installed, livestock stabilized and became more vital. The message is clear: clean water matters.
Turkey · 3,500 cows
"10 tons more water consumed daily, up to 750ml more milk per cow per milking, reduced flatulence in calves."
Nuevo León, Mexico
"Boiler cleaning extended from every 45 days to easy maintenance. Limescale became smooth and easy to remove."
Morocco · 3 farms
"After 2 weeks, new scale formed as powder. Old scale (5+ years) began breaking down. Cooling systems now efficient."
Turkey · Hydroponic Strawberries
"30-50% fertilizer savings, no blockages, stronger roots, increased water and fertilizer efficiency."
Turkey · Antalya Tarım
"Better roots, increased flower branch weight, higher nutrient transfer verified by leaf and soil analysis."
Mexico · Dairy Farm
"Scale-free cooling tower, no sprinkler damage, chemical elimination, quantifiable savings across bathing and cattle areas."
