Calcium scale is a hard, thick coating of calcium carbonate (CaCO₃) that forms on heating elements, in pipes, plumbing fixtures, water using appliances and R/O systems.
As calcium rich water enters the home, the carbonic acid/calcium equilibrium is interrupted within the pipes, plumbing fixtures, water heaters, appliances or water using devices. Because the Hydrogen Carbonate (Ca(HCO₃)₂) is a weak chemical compound, increases in temperature or water movement will cause the compound to breakdown, causing parts of the Calcium (Ca₂), Magnesium (Mg₂) and Bicarbonate (HCO₃) to attach to the surfaces of heating elements, the inside of pipes, water heaters, plumbing fixtures and water using devices. Over time the scale coating continually thickens and is very difficult and costly to remove.
What are the Effects of Calcium scale?
The negative effect of calcium is the scale it creates in or on pipe surfaces, water heaters, plumbing fixtures, heating elements, R/O systems and water using devices. The scale leads to higher energy, operating and maintenance costs for ice machines, coffee machines, reverse osmosis equipment, water heaters and other water using equipment. Scale will eventually lead to a reduction of water flow through restriction as the pipe gets more and more scale buildup. This is a common complaint from people who have been sold an inadequate system (too small) for the number of people in the home. The scale may also breed and harbor bacteria.
The photo below is from a home in Indian River County which, had a water softener but, was too small for the number of people in the home. Not only was the water softener too small but, the control valve was of poor quality and the control valve settings were incorrect. A water test would have been enough to shed light on the problem. The home owner told us, the water company they used never did any testing and kept telling her, nothing was wrong even though, she knew something was.
What Calcium Treatments are Available?
Water Softeners
The “classic” water softening unit operates on the basis of ion exchange; exchanging calcium and magnesium ions in the water for sodium ions. When a water softener is used, the result is not only soft water, but also increased sodium content in the water supply. Potassium chloride can be substituted for sodium chloride for those on extreme low sodium intake diets. However, sodium addition to one gallon of processed water, is less than a slice of bread.
Magnetic and Electric Systems for calcium scale control
Magnetic and electric systems are a relatively new invention and are considered by many in the industry as a gimmick. These systems only have a limited effectiveness at best, not a high enough percentage of effectiveness to prevent scale altogether. It is best to have a water test performed by a knowledgeable purification company for recommendations on the best course of action.
Polyphosphate for calcium scale control
The polyphosphate dissolves into the water and coats the iron, calcium and magnesium in it, making it difficult for these agents to precipitate and stick to the interior linings of pipes. This product has an ongoing expense and other solutions may be less of an expense.
Scale Prep SP3 Media for calcium scale control
The technologically advanced Scale Prep SP3 Media is an innovative solution that prevents all of the negative effects of calcium and magnesium, while allowing the positive health benefits to remain. Life span of the product media is worth investment.
How the Scale Prep System with SP3 Media Works
Scale Prep’s SP3 Anti-Scale Media was especially developed and manufactured to protect against the formation of scale and remove already existing scale from pipes and heat exchange surfaces.
The Scale Prep’s SP3 catalytic media prevents the formation of scale and eliminates existing scale by accelerating the transformation of the calcium and magnesium minerals into harmless “Nano” particles. As the nano particles flow through plumbing systems, they do not attach to pipes, fixtures, valves, or heating elements; the result is 99% scale prevention and removal!
Scale Prep’s SP3 is successfully used in a number of applications for both residential and commercial usage. Virtually maintenance free, chemical free, and salt free, Scale Prep’s SP3 media water conditioners are a cost effective alternative where benefits and overall performance surpasses our competitors.
The Scale Prep system, environmentally-friendly scale control:
- Commercial and Residential applications
- Preserves beneficial minerals
- Does not release harmful minerals or chemicals into our water system
- Maintenance free
- No electricity needed
- No wasted water
- Chemical and Salt free
- Eliminates existing scale
- Reduces soap and chemical consumption by 30-40%
- Reduces energy consumption
Scale Prep System Application Requirements
- Scale Prep System must be the last form of water treatment equipment installed with the exception of an RO unit or POU filter.
- Recommended to use a carbon pre-filter for municipal applications (carbon pre-filters reduces the negative effects of high chlorine on the media and lowest levels of iron .4ppm. Note: You must change out your carbon filter to keep proper flow rates).
- Recommended that you soak the media for 60-120 minutes before start up. This assures that the media is saturated with water and will not accumulate at the top of the housing when filled with water.
- Do not apply phosphates or any other anti-scalents either before or after the Scale Prep System.
- Scale Prep Systems are only partly filled with media; systems must have an adequate freeboard.
- Scale Prep Systems must use a Spider Flexible Hub and Lateral to ensure proper fluidization. (For larger tanks, use a hub and lateral with a garnet underbed.
Scale Prep System operates in the UPFLOW mode ONLY!!!! The tank connections are normally opposite from the standard down flow configuration. - Recommended to use a flow restrictor that is sized to the proper tank and water flow.
