How Do Resin Water Filter Cartridges Work?

A water softener removes minerals that create water hardness, one of the most common water quality problems.

What Is A Water Softener?

A water softener is a type of whole house filtration system which functions to remove calcium and magnesium minerals from the water supply via a process known as ion exchange. Water softeners help to mitigate one of the most common and destructive issues in the modern home – hard water.

What is Water Hardness?

Water hardness is related to the measurement of concentrations of magnesium and calcium minerals in the water supply. This is further divided into alkalinity, or temporary hardness, which refers to calcium and magnesium bicarbonate concentrations, and permanent hardness relating to concentrations of other calcium and magnesium minerals – such as sulphates and chlorides. The total concentration of the minerals in the water is known as the total hardness.

How Does A Resin Water Softener Work?

Our resin water softener systems contain a combination of different filters, each with different purposes.

Resin Cartridge

Our resin water filter contains a 10” column, filled with beads of polymer resin. The small beads create a large surface area in contact with water as it flows past.

The resin is made of polymer that binds positively charged ions. Initially the polymer surface is saturated with sodium ions, meaning that there are sodium ions available on the surface of each bead, ready for exchange. These ions are weaker than calcium & magnesium ions. The polymer is designed specifically to bind more strongly to the calcium & magnesium ions, than to the sodium ions.

When the hard water flows past the 1000’s of resin polymer beads, the calcium & magnesium ions will bind to the polymer, displacing the sodium ions into the water.

Kinetic Degradation Fluxion (KDF)

It’s a filter media that contains high-purity copper-zinc granules to reduce contaminants in water through a redox reaction – oxidation or reduction. The KDF process media reduces heavy metals, hydrogen sulphide, and chlorine. Once again, the technology of ion exchange is used here. Being a one-micron cartridge, it removes any contaminants larger than one micron, including the displaced salt ions from the Resin cartridge.

Sediment Filter

To maintain efficiency of the Resin & KDF filters, we have found in Western Australia that more frequent changing of the sediment filter is required, to remove increasing large particles before going through the other two filters. If this is not done, the work load is increased in the second two filters, reducing their efficiency for what they are designed to do: remove calcium, chlorine & heavy metals.

Benefits of Installing A Resin Water Softener System

Homeowners who install a resin water softener system to help combat water hardness will experience a range of benefits.

Saves You Money

Filtered water doesn’t carry the same calcium and magnesium ions that cause build up in your pipes and appliances, reducing the likelihood of having to front costly repair bills. Mineral build up in a pipe decreases the area that water can pass through, requiring higher pump pressure. This can also lead to an increase in energy requirements for managing the temperature of the water during heating or cooling. Your appliances also suffer from this build up leading to frequent repair or replacement of appliances such as hot water systems, dishwashers, washing machines and coffee machines.

Cleaner Hair & Softer Skin

Soft water also carries a range of benefits for the health of your skin and hair when bathing or showering. The mineral ions in hard water negatively affect the solubility of soap products, producing soap scum opposed to a smooth lather. Homes with water softeners will experience a deeper lather when compared to those without. A water softener can also lessen the effects hard water has on the natural oils found on our skin and in our hair.

Brighter & Cleaner Clothes

Hard water can also have harmful effects on your clothes during the washing process due to the presence of minerals that leave deposits. Over time, these minerals will cause fading of colours and may even stain whites. A water softener can assist in preserving the softness and fresh look of clothing which in turn results in savings as there is no longer a need for the use of fabric softeners.

Water that has passed through a filtration system also cleans clothes more effectively. This is due to the ease in which the water can dissolve into the clothes when compared with hard water.

Cleaner Dishes

Homes in hard water areas often experience a cloudy appearance on their clean glass and silverware after doing the dishes. No matter how many times you scrub those glasses, or what dishwashing products you use, the shine doesn’t seem to last. By installing a water softener for your home, you can rid the water supply of the minerals that cause this cloudiness before it enters your sink or dishwasher. Similarly to the shower products mentioned above, soft water fuses with dishwashing products more effectively, leading to a deeper lather and essentially a deeper clean.
