Understanding Water Hardness

Water hardness is a key factor in maintaining skin health and is determined by the concentration of certain minerals in your water supply.

Origins of Hard Water

Hard water is the result of water percolating through deposits of limestone and chalk which are largely made up of calcium and magnesium carbonates. The level of water hardness increases as the concentration of these minerals becomes higher. Generally, water hardness is classified as follows:

Soft: 0 to 60 mg/L calcium carbonate
Moderately hard: 61 to 120 mg/L calcium carbonate
Hard: 121 to 180 mg/L calcium carbonate
Very hard: Over 180 mg/L calcium carbonate

Effects on Skin Health

Your skin may feel the impact of hard water due to the high levels of calcium and magnesium. These minerals can leave your skin feeling dry and can exacerbate conditions like eczema by:

Stripping natural oils: Hard water can remove the skin’s natural oils, leading to dryness.
Residue: It can leave a residual film on your skin, which might clog pores and cause irritation or breakouts.

Principles of Water Softening

Water softening is a crucial process that transforms hard water into soft water by removing minerals like calcium and magnesium, which are responsible for water hardness. This section explains the underlying principles of water softening to help you better understand how it benefits your household.

Ion Exchange Process

Ion exchange is the most common method for softening water. At the core of this technology is an ion exchange resin where hard water passes through a tank containing negatively charged beads. These beads are usually saturated with sodium ions. As hard water flows through the resin, calcium and magnesium ions, which carry a positive charge, cling to the beads, displacing the sodium ions into the water. This process effectively removes the hardness from the water, leaving you with soft water that is gentler on your skin.

Steps of Ion Exchange:

Hard Water Entry: Hard water enters the ion exchange tank.
Mineral Exchange: Calcium and magnesium ions swap places with sodium ions in the resin.
Service Cycle: Softened water exits the tank for usage in your household.
Regeneration: Once the resin beads are saturated with hardness ions, a high concentration of sodium chloride solution flushes through the resin, allowing the beads to release the hardness ions and recharge with sodium ions.

Alternative Softening Technologies

While ion exchange is widely used, there are other technologies you might consider for water softening. These alternative methods include:

Salt-Free Systems: Instead of sodium, these systems use a template-assisted crystallization (TAC) process, which transforms the minerals in hard water into a crystalline form that prevents them from binding and forming scale.
Magnetic or Electronic Softeners: These devices claim to alter the electromagnetic properties of the minerals through a magnetic field or electrical charge, reducing scaling without removing the minerals from the water.

Each technology offers different benefits and may be suitable for different needs. Understanding the specific mechanics behind each method allows you to make an informed decision for your home.
