How It Works
How does DomesTAC work?
Template Assisted Crystallisation has produced the first effective chemical-free scale prevention method which converts hard minerals into harmless inactive microscopic crystals.
In cold water, calcium ions (Ca2+), magnesium ions (Mg+2), and bicarbonate ions HCO3-) are surrounded by layers of electrochemically attracted water molecules, which insulate against the natural tendency of the oppositely charged ions to come together and form crystals. Atomic-level templates on the surface of the DomesTAC media acts as catalysts and reduce the ability of water molecules to prevent calcium, magnesium and bicarbonate ions from coming together to form crystals of calcium and magnesium scale. This process that we refer to as Template Assisted Crystallisation (TAC) results in the creation of microscopic crystals of scale which rapidly form in the treated water, not on the contact surfaces of the water system and are carried downstream in colloidal suspension in the water system.
2013 Evaluation Using DVGW-W512 Test Protocol
TAC=Template Assisted Chrystallisation IX=Ion Exchange EIP=Electrically Induced Precipitation
MAG=Electromagnetics CDI=Captive De Ionisation
TAC Technology was the most efficient at reducing scale over the whole range of water qualities tested. In this evaluation, ion exchange (IX) was also tested, which gives a true comparison of IX to alternative devices and technologies under exactly the same conditions. The graph shows that both TAC and IX have the highest efficiency, with TAC performing better than IX.
At the lowest challenge (TDS 479 and CaC03 180) TAC had an efficiency of 99.6% and at the highest challenge (TDS 1200 and CaC03 500) 90% efficiency. In all water samples other alternative devices such as water conditioners only achieved 50% and below, with electro-magnetic being the worst.
TAC is exceptionally efficient, saves money, saves water and does not harm the environment.
The evidence shows that TAC is equally as efficient as ion exchange water softeners at preventing the formation of scale and has the added benefits of no salt use, no water waste from regeneration and importantly no harmful salt discharge into drains, groundwater and the wider environment.
