the feasibility is small.
this product of submarine is actually an OEM product of Swiss SAT(Swiss Aqua Technologies) company, and the address of official website is https://swatec.ch/zh. The product name is IPS KalyxX, and the principle of descaling is to use the patented technology of turbulent polarization (TGP).
Let the water flow through several groups of turbine-shaped electrodes made of different metals to generate a potential difference of about .8~1.8V, and generate a vortex water flow. Then, such a device can convert calcite, which is easy to generate hard scale in water, into softer aragonite (both of which are homogeneous polymorphs of calcium carbonate), which can be easily carried away by the water flow.
It can gradually soften and wash off the scale in the tap water pipeline in half a month to one month, which can reduce and prevent 76.3% scale accumulation, and its working life is at least 1 years.
in a word, the scale is softened and difficult to deposit by patented technology. This still sounds quite mysterious.
I have found some literature that most of the scale in the pipeline is indeed formed by calcite. Therefore, it is feasible to convert calcite into aragonite. The difficulty is that aragonite is unstable and easily converted into calcite. However, it is difficult to convert calcite into aragonite, which generally requires low temperature and high pressure environment.
The patented TGP technology of Swiss company is to solve this problem, and the related principle is only explained in its official website. Interested parties can study it.
There are two kinds of water softening technologies commonly used in water softeners. One is to remove calcium and magnesium ions from water by ion exchange resin to reduce the hardness of water. The other is nanocrystalline TAC technology, that is, Template Asisted Crystallization.
The free calcium, magnesium and bicarbonate ions in water are packed into nano-scale crystals by using the high energy generated by nano-crystals, thus preventing the free ions from generating scale. Compared with tap water, soft water has a very obvious taste and feel. Soft water has high oxygen content and low hardness, which can effectively prevent lithiasis, reduce the burden on heart and kidney, and is beneficial to health.
