What does calcite do for well water?
Calcite is a naturally occurring calcium carbonate media. One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to neutralize the water, raising its alkalinity until it reaches a non-corrosive equilibrium. It does not over-correct under normal conditions.
How does calcium carbonate filter water?
When acid water is passed through the APEX filter, the granular calcium carbonate neutralizes the acids and gives the water a neutral pH and eliminates the damaging, corrosive properties. Corrosion damage to pipes, faucets, dish washers and hot water heaters is eliminated.
Is lime good for well water?
Lime in all its forms – quicklime and hydrated lime, as well as calcined dolomite – are the most effective and cost efficient alkaline products used in the making of drinking water, as well as in the treatment of waste water and sludge.
How do you treat lime in well water?

Can you add calcite to a water softener?
If your water has an extremely low pH level or a high flow rate, you will need to mix four parts of calcite with one part Corosex and add the calcite mixture to the tank instead of pure calcite. Clean up any spilled water with a towel.
Are calcite filters safe?
Calcite is a naturally occurring calcium carbonate mineral which is often used to treat acidic water conditions and is completely safe for use with drinking water. These filters will make water less aggressive by increasing the alkalinity of soft water while improving the overall chemical balance and taste.
Is calcite safe to drink?
The hardness of a crystal will determine if it is safe to place in water. You can use Moh's Scale of Mineral Hardness to see how hard your crystals are but it isn't very comprehensive. Any crystal from the quartz family is safe to put in water, as are calcite stones.
How do you make calcium carbonate?
Pure calcium carbonate can be produced from marble, or it can be prepared by passing carbon dioxide into a solution of calcium hydroxide. In the later case calcium carbonate is derived from the mixture, forming a grade of product called "precipitated calcium carbonate,” or PCC.
Are carbon water filters worth it?
Whole-house systems with carbon filters are the most economical option, and they also require the least maintenance. These filters generally don't need to be replaced for at least three years, and they remove one of the most common contaminants: chlorine, which reduces the chance of poor-tasting water.
How long do activated carbon filters last?
What Is The Average Life Expectancy Of a Carbon Filter? Carbon filters should be replaced after 18-24 months of continuous (24/7) usage. Although this may vary depending on the company product, it has been shown that carbon filters can last for up to four years.
What is CCPP in water?
Carbonate calcium potential precipitation (CCPP) is an interesting parameter for quantifying what may be scale-forming or may have dissolving properties (pipes made from concrete) knowing that the CCPP is a level of concentration expressed in CaCO 3 (positive if water can cause scaling or negative if water is aggressive).
What is Table 44?

What is a hard water temperature?
For example, water that has a TH < 5 °F will be termed "soft", and "hard" from a TH of between 15 and 20°C.
What is natural water?
As discussed in the sections water’s chemistry, terms used by water analysts and natural water, it is the geological structure of the ground that collects, drains and stores water and that helps to determine the water’s "appearance".
Does mineralised water have a higher pH?
Note: later on, we shall see that the pHs value of water rises as its M-alk. (and, therefore, its mineralisation) decreases. E.g. (figure 99) for a pH that is systematically set to 8 (discharge into a mains system), lightly mineralised water will have a higher pHs and will, therefore, still be aggressive; on the other hand, a more mineralised water will have a lower pHs and will, therefore, be scale-forming; this explains the degree of "correlation" that links soft water with aggressive water, or hard water with scale-forming water, despite different meanings.
Is calcium bicarbonate soluble in water?
A particular feature of calcium bicarbonate is that it only exists in the dissolved form; when it precipitates, it does so in the calcium carbonate form, one that is only slightly soluble and it can only remain in water when it is balanced out by available CO 2:
How does calcite work?
The calcite and calcite-blend neutralizers work by adding calcium to the water, and it will increase the calcium hardness of the water, making the water ‘harder’. However, most acidic well water is soft to begin with and after passing through the neutralizer will be harder, but not hard enough to warrant a water softener.
How to raise pH in well water?
One of the most convenient methods to raise well water pH, hardness, and alkalinity is to use a calcite neutralizer filter. These filters will typically raise the pH of the well water from 7.0 to 8.0 and add 30 to 100 ppm of hardness depending on the alkalinity and water hardness.
What pH should a calcite tank be?
Calcite Neutralizer tanks with natural crushed and screened pure calcium carbonate easily neutralize acidic waters from 6.0 to 6.9. Below 6.0 a blend of calcite and ‘Corosex©” is recommended.
What causes corrosion in water pipes?
On private water systems, one of the most common causes of pipe and fixture corrosion is from low pH, which can be defined as acidic water with a pH of less than 7.0 pH. Signs of acid water are corrosion of fixtures, blue staining (from copper pipes) or rust staining (from iron pipes). Common causes for acidic water are acid rainfall due ...
What does it mean when your toilet tank is blue?
If you see blue stains, or blue-green deposits this indicates copper pipe corrosion. If you see rust stains or rust deposits this can indicate iron pipe corrosion or there may be iron naturally occurring.
What does a negative number of 0 mean?
A negative number of less than 0 indicates the water is corrosive. Generally, the lower the pH, the lower the hardness and alkalinity, and the higher the total dissolved solids will mean the water is more corrosive .
What causes acidic water?
Common causes for acidic water are acid rainfall due to atmospheric carbon dioxide and other airborne pollutants, runoff from mining spoils and decomposition of plant materials. Corrosion is a natural process involving chemical or electrical degradation of metals in contact with water.
What is backwash system?
Backwash systems are the most common acid neutralizer units on the market today. These systems consist of a mineral tank and a control valve. The mineral tank contains a calcite media, or a combination of calcite and magnesium oxide.
What is a softpro neutralizer?
The SoftPro pH Neutralizer is a water filtration system that uses calcite to adjust the pH of water. Assembled in the USA, this unit uses an NSF-certified smart control valve to add the optimum concentration of calcite to water, preventing green stains and corrosive acid damage to your pipes.
What is the pH of Springwell Calcite?
The Springwell Calcite pH Neutralizer incapable of neutralizing water in the 6 to 6.5 pH range. The system uses calcite, which slowly dissolves into water. This boosts pH and reduces the risk of contamination from metals like lead and copper in plumbing.
How to increase pH in water?
To increase water pH, a calcite acid neutralizer will dissolve calcium carbonate into your water. Calcium, along with magnesium, is one of the minerals that is responsible for water hardness.
How long does an acid neutralizer last?
Most acid neutralizers last for at least 10 years. A good indication of how long a system will last is its warranty. You’re looking for a warranty of 10 years at least. A limited lifetime warranty is even better.
What is the best way to neutralize acidic water?
Calcite is the most available and affordable means of neutralizing acid water. Many neutralizing systems use calcite to raise water’s pH. The calcite is stored in a tank and used to treat water before it enters your home.
What happens when rain occurs?
When precipitation (rain) occurs, water is returned back to earth. Carbon dioxide in the air dissolves into the rainwater, and carbonic acid is formed. This results in a rainwater pH of around 5.6.
Why use chelating agents?
Chelating agents are especially useful in wells experiencing heavy iron or iron bacteria fouling where removal of iron deposition is important to improving flow and operation. Chelating agents are often added to dispersants and used in conjunction with acids in an effort to improve cleaning efforts.
What are the three aspects of well rehabilitation?
Before we go any further, let’s break down the three main aspects of well rehabilitation. First, there is disinfection. Disinfection occurs at the completion of construction of the well following modification or pump work, at the end of cleaning efforts, and periodically in an effort to target bacterial issues.
What is water scale analysis?
Water and scale analysis, coupled with pump tests and video surveys, can give us better insight into the condition of the well structure and the location of various fouling mechanisms. These advances have also impacted the way we respond to different problems.
Why do we use caustics in water wells?
Caustics are occasionally used in water well cleaning as the base chemistry to remove oil contamination and some heavily biological fouling. The use of caustics is limited though as they have almost no effect on mineral compounds, and in some cases can alter the water chemistry to form scale during treatment.
What is chemical cleaning?
Chemical cleaning is typically a combined chemical and mechanical effort that targets mineral scale, biomass, or combinations of both. Chemical cleaning is generally acid based, but may also include dispersants, surfactants, inhibitors, and in some rare cases, may use a caustic solution.
Why is it important to remove this material?
Why is it important we remove this material? Simply put, leaving the disrupted materials or introduced chemicals behind leaves the building blocks for future fouling. By leaving the dissolved material behind, we are continuing the chemical congestion that led to the formation of solids, enhancing the process, and reducing the time for the return of fouling.
How effective is corrosion inhibitor?
Corrosion inhibitors are typically used in conjunction with mineral and organic acids in an effort to reduce the acid’s attack on the metal structures downhole.
