The Superior Water Softener Alternative

Summary of Commercial Water Filtration Systems

Next ScaleStop systems are available in a range of sizes in single tanks with continuous flow capacities of up to 75 gallons per minute for the NSS-1665. For higher flow demand, multiple tanks are installed in parallel. Installation is quick and easy with only inlet and outlet connections. No need for a potable water bypass, no need for a drain, no electrical connections, no controller to set.

For years, water softeners have been virtually the only means of treating hard water. Other alternatives including magnets, electromagnets, RF devices and catalysts have been available but few have proven to be effective.

Technology Breakthrough

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

Tested and Proven

Tested by an independent laboratory against the international protocol for scale prevention, Next ScaleStop achieved a 99.6% effectiveness rating - the only technology to do so and far more effective than the other water softener alternative. Proven on over many years of successful use in homes and business.


Next ScaleStop Science and Technology Overview

ScaleStop Physical Treatment Versus Chemical Treatment

ScaleStop does not require chemicals such as sodium, potassium, acids or phosphates to produce a scale-free effect in water distributions systems and especially water heating equipment. ScaleStop is a far simpler "physical water treatment" and does not extract or sequester the water hardness constituents of calcium and magnesium, but rather consistently influences the crystal structures of these minerals in such a manner that no scale is formed on interior surfaces. ScaleStop neither adds chemicals nor removes chemicals from the water.

To be more specific, rather than attempting to prevent the natural tendency of hard water to form scale (by removing or adding chemicals), ScaleStop treatment actually promotes and redirects scale formation in such a manner that the scale remains suspended in the water rather than forming on surfaces within the water system.

How Does ScaleStop Work?

In cold water, calcium ions (Ca2+), magnesium ions (Mg+2) and bicarbonate ions (HC03-) 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 ScaleStop media act 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 Crystallization (TAC) results in the creation of microscopic crystals of scale (seed crystals), which rapidly form in the treated water, not on the contact surfaces of the water system, and are carried downstream in colloidal suspension through the water system.

Next ScaleStop Plus Versus Saline Water Softeners

Each of our ScaleStop Plus Template Assisted Crystallization water filtration systems is exceptionally efficient, saves money, saves water, and does not harm the enviroment. The evidence from independent testing shows that ScaleStop Plus Template Assisted Crystallization 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, no electricity use, and importantly, no harmfull brine discharge into drains, groundwater and the wider enviroment.

Next ScaleStop Plus Water Softeners
Technology Template Assisted Crystallization: physical process of combining hard water mineral ions (calcium and magnesium) into microscopic crystals which do not bind to materials to form scale. Salt Ion Exchange: Chemical process involving replacing and removing hard water mineral ions (calcium and magnesium) which cause scale with sodium ions from salt.
Method Salt-free water filtration Salt-based water softener
Scale Prevention 99% scale prevention 41% to 96% efficient, depending on owner maintenance
Health Retains healthy minerals while adding nothing to water Removes healthy minerals (calcium, magnesium, copper, and iron). Adds sodium to water
Maintenance Virtually no maintenance Constant salt replenishment
Water Use None additional Regeneration and backwashing wastes thousands of gallons of water annually
Electrical Use Uses no electricity Constant use of electricity
Environment Adds nothing to waste water Brine discharge contaminates ground water and increases total dissolved solids (TDS) in sewage.
Physical Size Compact, easy to fit in Bulky, must accommodate salt storage
Operating Cost Very economical Substantial cost for salt, electricity, and water
Regulatory No legal restrictions Use is legally prohibited in some areas
