The Scale Problem
What is Scale?
Many building owners and maintenance personnel are all too familiar with the troubles of scale. But, just what is it? Scale is an incrustation of calcium carbonate (CaCO3) that forms on imperfections on heating elements or within plumbing systems. It is primarily composed of calcium (Ca2+), magnesium (Mg2+) and bicarbonate (HCO3). Scale deposits grow over time and are highly insoluble, making scale extremely difficult to remove once formed and often leading to costly remediation efforts.
Why is Scale Harmful?
There are a number of issues associated with the growth of scale. First, as scale forms over time, it reduces the inner diameter of pipes and elbows, ultimately leading to restrictions in flow rate and pressure loss problems in systems. Second, scale often becomes encrusted on internal moving parts of valves & components, affecting their intended purpose or worse, causing safety failures. Lastly, in a boiler or hot water tank, heating elements can become coated with scale, reducing system efficiency and increasing operating costs for end users.
Scale Control Technologies
Before OneFlow®, the most common approach to dealing with scale was the installation of a water softener. The never-ending consumable cost of salt, required for system regeneration, is expensive and must be considered in the overall cost equation. Although effective in dealing with most scale, water softeners come with some significant drawbacks including:
- Harmful chloride discharge that negatively impacts the environment
- The removal of beneficial minerals (calcium & magnesium) from drinking water
- A backwashing and regeneration process that wastes water
- Large floor space requirements for operation and storage of salt bags
Scale Inhibitors or Sequestrates
Scale sequestering systems introduce phosphate-based chemicals to inhibit scale. These systems work better in cold water applications but have a tendency to break down or fail in hot water. Similar to softeners, scale sequestering systems require the constant introduction of a chemical resulting in ongoing monthly costs to end users.
Magnets and Other Devices
Magnets, electro-magnets, radio frequency devices, electrical current systems and other "black magic" inventions have failed to pass any scale control standards designed by internationally recognized 3rd party testing agencies. While the manufacturers of these products may have in-house data to support their amazing scale control claims, none of these products have ever passed any international protocol for scale prevention. "Buyer Beware" is the best advice one can take if considering this gadgetry.
The Catalyst for Change
Now there’s OneFlow®, the first physical water treatment technology to effectively control scale. Independent scientific testing has confirmed Template Assisted Crystallization (TAC) technology provides scale reduction of over 95+%. Testing was conducted under protocol based on DVGW W512 test to access control of scale formation.
