We subjected the samples of milk serum - whey - and washing water of the dairy to cavitation cycles with the initial only aim of reducing the levels of pollutants present and therefore being able to proceed with the disposal of the resulting water so as not to have to return it to landfill.
Each liquid was subjected to a double standard loop cycle lasting 10 minutes.
After the first loop, 35% of the proteins and 80% of the animal oils and fats were extracted from the whey and milk serum samples, while 80% of the proteins and 85 % of animal oils and fats were extracted from the washing water of the dairies.
The extraction takes place in an extremely simple way as proteins, oils and fats are placed on the surface of the liquid and therefore can be removed with a simple spatula systems.
Therefore, after the first treatment carried out inside the EMPOWERING DEVICE and useful for the separation of fats both on the whey and milk serum samples and on the washing water of the dairies, we proceeded to subject both fluids again to a new loop inside of our apparatus.
We take note that, once the majority of the fats are removed, during the second cycle the waters benefit greatly from an heavy cavitation treatment, because the EMPOWERING DEVICE will not take unnecessarily machine time and energy in the pursuit to break down the fat and protein molecules but will immediately take action on the removal of COD and BOD.
In particular, after the treatment, the whey and milk serum see both values cut by 36% while the washing waters of the dairies see both values cut by 11%.
A result so evident that it stands out at first glance: the effect on the samples subjected to cavitation cycles within the EMPOWERING DEVICE was immediately evident, highlighting the possibility of recovery of unexpected but large quantities of nutrients still present.
So, the fluids delivered to us as exhausted and therefore, theoretically, intended to be simply recycled as process water after a possible purification, lend themselves instead to become an interesting source of additional income for breeders or dairy businesses thanks to the extraction of the residues produced that can be easily processed, for example, into pharmaceutical and / or food supplements.
For each liquid we took samples of the liquids to be treated and samples of the liquids after subjecting them to cavitation, then we sealed the bottles and sent everything to the laboratory where we had the necessary and appropriate analyzes conducted.
The Laboratory also informed us that was emerged an unforeseen action of our machinery, in each of the liquids subjected to the two cycles and which also affected the dissolved salts: the treatment produced an interesting increase of the conductivity of the fluids.
