Chemical additives are used to control pH, thermal capacity, corrosion, etc.
They are expensive
System requires constant monitoring & maintenance to assure proper conditioning.
Chemicals may be hazardous to employees or environment whenever processess fluids are flushed /spilled.
May incur unwanted pressure drop increasing energy requirements. |
Salt based water softeners utilize the ionic exchange of the Sodium in salt (NaCl) for the Calcium (CaCO3), or other mineral, in the water (NaCl + CaCO3 = CaCl + NaCO3).
While soft water is produced, a considerable expense is incurred (price of softener, salt supplies, replacement of the ionized bed, the softener's average life of 7 years, health risks).
Sodium must be added to the water in place of the mineral that is removed ("salt-ion exchange").
The mineral deposits slowly damage the system.
The sodium released into the softened water is corrosive (the corrosion due to scale has been replaced with corrosion due to sodium - an undesirable trade-off).
Health & environmental hazard due to hypertensive effect of sodium on human body (the delicate electrolytic balance of sodium/potassium ions is unsettled) and danger of sodium toxification to the area ground water (in increasing areas the communities, doctors, hospitals and rest homes prohibit salt-ion exchange systems).

Involves forcing untreated water through a membra-ne that selectively filters certain constituents out off the fluid.
The system requires very high pressure because the membrane used as the filter medium is essentially non-porous.
In areas that have high mineral or salt content, the membranes must be flushed frequently (and replaced often).
This always requires downtime and a major usage (loss) of water. R/O units typically waste half of the processed water.

Nothing is added to the fluid - it works by rearranging the molecules already present in the fluid and additives are unnecessary.
No power required - permanent magnets supply "free" effective energy. No power supplies to burn out.
No continuing maintenance required after the installation and no recharging or further attention is needed following the initial techniques and/or the Stabilization Period.
A "Snap-On" design, unlike the other solutions that are "inline" and become part of the system is removable (and portable) allowing risk free testing & installation. |
