How Scale Stop Plus Works

THE MAN BEHIND THE VISION
ROBERT SLOVAK

Robert Slovak, a degreed Mechanical and Astronautical Engineer, has over 30 years of experience in the water treatment industry, specializing in membrane separation technology and products.  His career included a “significant contribution” to the POU (Point-of-Use) and commercial/institutional RO (Reverse Osmosis) industry, especially in the area of system design, application knowledge, and technical training.
Robert and his brother Jack co-founded Water Factory Systems in the early 1970’s.  After gaining valuable research and field experience, they joined forces with Doug Horn of Pro Water Systems.  The combination rapidly became one of the industry leaders in POU and commercial RO water treatment.  As the field was so new, Robert was required to contribute in areas of research, engineering, product development, manufacturing, installation, marketing and sales.
Water factory Systems was purchased by the publicly traded Commercial Intertech/CUNO Group in 1989.
It subsequently became solely part of CUNO Incorporated, a global leader in fluid purification, which was spun-off as an independent, publicly traded company in 1996.
CUNO Incorporated has recently been acquired by the 3-M Group and the Water Factory Systems division was an integral part of this acquisition.
Of his contributions to the water treatment industry, Robert is perhaps best known for his articles, technical writing, and training seminars, through private industry and numerous Water Quality Association functions.  Today, Robert lives in the Lake Tahoe area of Nevada where he does international consulting and specialized water treatment projects on a limited basis, leaving enough time for other more adventurous activities of the mind, body and spirit.
Robert is the Principle Officer of NEXT™ Filtration Technologies, Inc. whose products include:  NextRO®; NextScaleStop®, and NextSand®, all of which are State-of-the-Art technologies all of which are incorporated into products sold by H2O Profesionales Internacionales, S.A. de C.V.

Scale Stop Plus®
Physical
Vs.
Chemical
Treatment

Scale Stop Plus® 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. Scale Stop Plus® 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. Scale Stop Plus® 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), Scale Stop Plus® 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 Scale Stop Plus® Work?

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 Scale Stop Plus® 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.

  • In untreated water, the scale forms on the inside walls of pipe, exterior of fixtures and all heating surfaces.
  • In ScaleStop treated water, the seed crystals themselves provide a far greater surface area for new scale formation. Therefore, new scale preferentially deposits on this continuously replenished stream of suspended crystals rather than on the water contact surfaces – especially those surfaces that are at elevated temperatures.
  • Since scale formation is not static (it is constantly forming and dissolving),the existence of continuously generated seed crystals not only eliminates further deposition of scale on water contact surfaces, but in fact will cause deposited scale to gradually dissolve back into the water and deposit on passing seed crystals in the water (from contact surfaces to solution to seed crystals).

Atomic sized nucleation sites on the surface of small polymer beads convert dissolved hardness into microscopic crystals.

Once the Crystals grow up to a certain size they are released from the bead. The crystals in solution keep the hardness out of the water so that it can’t form scale or interfere with soap.

Water
Softeners

  • The calcium and magnesium removed by traditional salt-using softeners are essential nutrients, while the sodium added is suspected to aggravate certain cardiovascular health problems and contribute to weight gain.
  • Scale Stop Plus® systems do not add anything or remove anything from the water, retaining the important naturally occurring minerals, especially calcium and magnesium.
  • Salt-using softeners must be regularly recharged by adding more salt and back-flushing with fresh water, which is costly, inconvenient, corrosive to pipes and water heaters, harmful to the environment and wasteful of a precious resource.
