Supply Chain Phase


Next StcaleStop is an innovative and proven technology which is a credible alternative to ion exchange water softeners in the treatment of hard water to protect from limescale formation - CaC03. The technology employed is Template Assisted Crystillisation or TAC which functions at the molecular level by converting harmful CaC03 (the cause of limescale) into harmless microscopic crystals which remain suspended in the water and are unable to stick to surfaces. The invisible crystals are sub micron and easily pass through RO (reverse osmosis) membranes.
The technology has been demonstrated to be equal in efficiency to ion exchange water softeners in independent evaluations using the German DVGW-W512 testing protocol which is the Internationally recognised efficiency test for scale prevention.
TAC does not use electricity, salt or chemicals and unlike ion exchange water softeners, does not waste water in a backwash and regeneration process or discharge brine into the drains or wider environment.
TAC meets International drinking water standards including NSF61 and BS6920 

Potential Benefits

Food manufacturing and processing uses large quantities of water in production operations. The hotel and hospitality sectors can also make significant savings by switching from ion exchange water softeners to TAC systems.   This innovative approach to scale prevention, reduced water waste and zero brine discharge, has great potential to reduce primary water usage with a corresponding cost reduction in water charges, salt purchase, maintenance, and effluent charges.  Competitive advantage can be achieved from the significant cost reductions and an environmental benefit is also achieved.
The issue is not about the efficiency of ion exchange water softeners, rather the associated costs of operation, the waste of water, the addition of sodium to treated water and the discharge of harmful brine into the wider environment. TAC systems have none of these operational costs, they add nothing to the treated water, have zero water waste and zero discharge into the environment. Capital cost of TAC systems is lower than ion exchange water softeners of the same capacity. In commercial applications the return on investment with a switch from water softeners to TAC is typically one year or less.

Consultant View

This water treatment development has the potential to significantly reduce the usage of water in food processing operations and in the hotel and hospitality sectors. The concept would be transferable to other manufacturing and processing operations across a variety of industry sectors. The system is fully developed and is proprietary to Next Filtration. The potential savings demonstrated and rapid return on capital invested should encourage Facility Managers to investigate this innovative water saving technology and cost efficiency programme. Water savings deliver both commercial and environmental benefits.
