A recent development, Template Assisted Crystallisation (TAC), has produced the first effective chemical-free scale prevention method. Based on TAC technology, Next Scale Stop converts hardness minerals into harmless, inactive microscopic crystals.

• Technology introduced in 2004 - Relatively new to water treatment
• A reaction is carried out on a honeycomb structure template
• Used to make well ordered micrometric and nanometric structures
• ZnO nanosheets, Photonic Balls
• Uses Polymeric Beads with nucleation sites to convert dissolved hardness into microscopic crystals
• Once crystals grow to the template size, the crystals are released and remain in the water without forming scale
• Operates as a fluidized bed to maximize surface area and effectiveness
• Commercially available for a variety of flow rates

The graph above and the table below are taken from 2013 independent evaluation using the German DVGW-W512 testing protocol. It is clear that Next Scale Stop 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 had the highest effiency, with TAC performing better than IX.

At the lowest challenge (TDS 479 and CaC0₃ 180) TAC had an effiency of 99.6% and at the highest challenge (TDS 1200 and CaC0₃ 500) 90% effiency. In all water samples, other alternative devices (water conditioners) only achieved 50% and below, with electro/magnetic being the worst.

TAC is exceptionally efficient, it saves money, saves water and does not harm the enviroment.
The evidence shows that Next Scale Stop TAC is equally as efficient as ion exchange water softners at preventing the formation of scale, and has the added benifits of no salt use, no water waste from regeneration, and importantly, no harmfull brine discharge into drains, groundwater and the wider enviroment.

Parameter	TDS (mg/l)	Hardness (mg/l as CaCO3)
Salt River Water (Tempe Tap Water)	479	180
Central Arizona Project (CAP) Canal Water	666	150-250
Scottsdale Groundwater	1200	450-500
Santa Clara Valley Water District (SCVWD) Groundwater	420	210

Each water quality has a unique make up of a total dissoved solids and hardness levels.
