Increase the pH of Acidic Water to Neutral

What Is Acid Water?

Acid water is water with a potential hydrogen (pH) of less than 7. pH refers to the amount of hydrogen ions mixed in with the water. pH is measured on a scale from 0 to 14, and 7 represents neutral where the water is neither alkaline nor acidic. Zero through 7 indicates acidity, the lower the number the higher the acidity. Seven through 14 indicates alkalinity, the higher the number the higher the alkalinity.

Like the Richter scale for measuring earthquake intensity, the pH scale is logarithmic. A solution with a pH of 8.0 is ten times more alkaline than a solution with a pH of 7.0. A solution with a pH of 9.0 is 100 times more alkaline than a solution with a pH of 7.0.

Why Is Acid Water Bad?

Although there are many beneficial uses of acidic water -- it is a natural astringent for washing your face, it can relieve dry and itchy skin, it can expedite the healing of skin problems, it can kill bacteria when washing produce, etc. -- a low pH of less than 6.5 can wreak havoc in your home.

The corrosive nature of acidic water causes metal ions such as iron, manganese, copper, lead and zinc to leach into the water, causing elevated levels of toxic metals in your water. Signs of acid water are corrosion of fixtures, blue staining (from copper pipes) or rust staining (from iron pipes). Acidic water can also cause pinhole leaks and pipe failure over time. It may also cause aesthetic problems, such as a metallic or sour taste.

How to Raise Water's pH

One of the most convenient methods to raise pH is to use a calcite, which is a crushed and screened white marble media which can inexpensively be used to neutralize acidic or low pH waters to a neutral, less corrosive effluent. A Calcite filter will typically raise the pH of the water to around 7.0 and add 1-3 grains of hardness (30 to 50 ppm of hardness) depending on the alkalinity level and the amount of calcium and magnesium (hardness) of the water. Calcite has the same properties of Himalayan rock salt in that when salt rocks are added to water, the rocks stop dissolving when the water pH hits 7.0. When all the calcite has been dissolved, that means it is time to add more calcite.

One of the advantages of Calcite is its self-limiting property. When properly applied, it corrects pH only enough to reach a non-corrosive equilibrium. It does not overcorrect under normal conditions. Upon contact with Calcite, acidic waters slowly dissolve the calcium carbonate to raise the pH, which reduces the pipe corrosion potential of leaching of copper, lead and other metals found in typical plumbing systems. Periodic backwashing will prevent packing, reclassify the bed and maintain high service rates. Depending on pH, water chemistry and service flow, the Calcite bed will have to be periodically replenished as the Calcite is depleted.

NOTE: How long the calcite media lasts depends entirely upon the level of water hardness, and can last from 6 months to 2 years.

Backwashing Frequently Asked Questions

Lots of folks have asked questions about the backwashing head on the whole house system. Here are the five most commonly asked questions and the answers.

What is backwashing?
Backwashing is the process of forcing water through the filter in the wrong direction to unclog the dirt and sediment which has blocked the filter. Auto-backwashing filters refresh (backwash) themselves periodically to insure an optimum level of performance and to prevent "channeling". Whole house auto-backwashing filters greatly enhance the performance of softener systems. Backwashing is a common practice for certain whole house and commercial units which are treating large volumes of water for utility purposes but it is not a recognized practice for small point of use drinking water systems.

How many gallons does it use in the backwash?
Around fifty gallons. It could be slightly more or less depending upon water pressure.

How long does the backwashing last?
It lasts approximately 10 minutes.

What is the flow rate of the backwash water?
5-7 gallons per minute flow rate

Does it have to backwash every day?
It's advisable to backwash daily but not mandatory. Often times systems on municipally treated water backwash once every three or four days. Systems on wells are urged to backwash daily. The frequency of backwash depends greatly upon the quality of water.
