Everything you need to know about TAC

Total Alkalinity, or TAC, is a crucial parameter for understanding and optimizing the quality of your water. Often overlooked, it plays an essential role in water balance, directly impacting its comfort and flavor. Let's explore together the ins and outs of this important indicator.

What is TAC?

TAC measures the concentration of carbonate and bicarbonate ions present in water. These ions, commonly referred to as alkaline, give water its buffering capacity, meaning its ability to neutralize acids and bases.

In other words, TAC acts as a protective shield against sudden pH fluctuations, ensuring stable and pleasant-to-use water.

Balanced TAC for Optimal Water

An ideal TAC generally ranges between 8 and 12 French degrees (°f).

• Low TAC (below 8°f) makes water corrosive, potentially damaging pipes and appliances. It can also have an unpleasant metallic taste.

• High TAC (above 12°f) promotes scale formation, causing faucet and showerhead scaling and reducing detergent efficiency.
  

Maintaining Balanced TAC

To ensure optimal TAC, it's important to regularly monitor its value. Simple and affordable analysis kits are available in stores.

In case of imbalanced TAC, corrective solutions exist:

• For low TAC, it's possible to add an alkaline product, such as caustic soda or calcium carbonate.

• For high TAC, water can be diluted with distilled water or a water softener can be used.

Advantages of Balanced TAC

Balanced TAC offers numerous benefits:

• Stable and pleasant-to-use water

• Protection against corrosion and scaling

• Better taste and odor of water

• Increased detergent efficiency

• Extended lifespan of installations

TAC: An Ally for Your Well-being

In summary, TAC is an essential parameter for quality water. By monitoring and maintaining it within an optimal range, you not only preserve your installations but also your health and well-being.
