How To Raise pH In Well Water: Problems Caused By Acidic Water
Here are the problems caused by acidic water:
Exposure To Heavy Metals
Water with a low pH is more prone to containing elevated levels of heavy metals. Due to the lack of minerals in low-pH water, it tends to scavenge and accumulate various substances along its path to your faucet to restore a neutral pH level.
Consequently, when water flows through your pipes, it has the potential to collect metals that you subsequently consume.
Exposure to heavy metals can cause health effects, including symptoms like vomiting, diarrhea, shortness of breath, and potential organ damage. Additionally, consuming acidic water can harm your teeth and bones.
Corrosion
The presence of acidic water triggers a process known as corrosion, which gradually deteriorates materials over time. As your pipes begin to dissolve, they become more vulnerable to leakage. Moreover, the metals from these corroding pipes can detach and contaminate your drinking water supply.
How To Raise pH In Well Water: Ways To Fix Acidic Well Water
Here are the ways to raise pH in well water:
Neutralizing Filters
Neutralizing filters are an effective and straightforward way to increase the pH of well water. These filters use calcite, a naturally occurring calcium carbonate mineral, as the primary filter media. Calcite dissolves when it comes into contact with water, which helps increase the pH level of the water.
In some cases, Corosex (magnesium oxide) can be mixed with calcite to increase the pH-boosting effect. Neutralizing filters work like whole house filters, ensuring every tap delivers non-acidic water.
Neutralizing filters are easy to install and maintain. You can use a combination of calcite and Corosex for a stronger effect. This treats water for the entire home.
Soda Ash Feeders
Another method for raising the pH in well water is using a soda ash feeder, also known as a chemical feed pump. This device injects a pre-set amount of soda ash (sodium carbonate) solution into your water system. Soda ash is a pH-boosting compound that neutralizes acidity and acts as a water softener.
To use a soda ash feeder, you’ll need to:
- Mix a soda ash solution by dissolving soda ash in water
- Connect the feeder to your plumbing system
- Adjust the feeder settings to control the solution injection rate
Soda ash feeders are a more aggressive method for raising pH levels and are typically recommended for cases with extreme acidity.
Calcite Media
Water with a pH of 6 to 6.5 can be effectively treated using an acid neutralizer with calcite media. This particular treatment material, derived from crushed white marble, is designed to address the needs of acidic water.
Treating water with calcium carbonate leads to an elevation in its pH level. This process mirrors the natural environment, where water flowing through calcium-rich rock formations experiences a similar pH increase.
Typically, a neutralizing filter is supplied with a set of calcite media included in the initial purchase.
pH Adjusting Chemicals
If you’re looking for a simpler and more budget-friendly option, pH-adjusting chemicals like soda ash, sodium hydroxide, and calcium carbonate can be added directly to your water supply. These chemicals help neutralize acidic water and increase the pH level. However, this method may require frequent monitoring and adjustments to maintain the desired pH levels.
While using pH-adjusting chemicals might be affordable, it may not provide a comprehensive solution like neutralizing filters or soda ash feeders.
In summary, you can raise the pH of your well water using neutralizing filters, soda ash feeders, or directly adding pH-adjusting chemicals. Each method has benefits and drawbacks, so select the one that fits your needs & budget.
Calcite-Corosex Blend Media
Although calcite media is generally suitable for various situations, there may be instances where you encounter highly acidic water with a pH level lower than 6. In such cases, combining magnesium oxide and corosex can be more effective.
This combination can raise water’s pH by up to 1.5 units, surpassing the typical 1-unit increase achieved with calcite media.
For the combined use of calcite and corosex, adding approximately 10% to 20% magnesium oxide and 80% to 90% calcite media is recommended. This composition ratio ensures the desired effectiveness and pH adjustment when treating acidic water.
It is essential to consider that using calcite and magnesium oxide to treat acidic water will increase the hardness of calcium and magnesium minerals.
How To Raise pH In Well Water: Alternative Solutions
Here are the alternative solutions and best practices for raising pH in well water:
Reverse Osmosis Systems
Reverse osmosis systems are an effective solution for treating acidic well water. These systems force water through a semipermeable membrane, removing impurities and acidic particles.
As a result, reverse osmosis systems provide cleaner, mineral-balanced water with a more neutral pH. However, choose a system with a remineralization stage to add essential minerals to the purified water and increase alkalinity.
Water Softeners
Water softeners can address hard water issues, which often coexist with acidic well water. While they do not directly raise pH levels, water softeners prevent scale build-up, prolonging the life of your appliances and plumbing system.
By removing calcium & magnesium ions and replacing them with sodium or potassium ions, water softeners produce softer water, reducing hard water spots and soap scum.
Alkaline Water Filters
Alkaline water filters are specifically designed to increase the pH of water, making them an excellent solution for well water. These filters typically use calcite or other pH-boosting media to neutralize acidity while adding essential minerals like calcium carbonate. As a result, alkaline water filters provide healthier and better-tasting water with a more balanced pH.
Some popular alkaline water filters include:
- Calcite-based neutralizer filters: Raise well water pH from 7.0 to 8.0 & add 30 to 100 ppm of hardness.
- Acid-neutralizing filters: Attach to your plumbing system to increase alkalinity and provide pH-balanced water throughout your home.
