Water softener resin

Water softener resin is an important component of the water softener system. For water softener systems to fucntion effectively, one requires to understand the importance of the water softener resin bed. The resin bed, resin media, and resin beads are important components that carry out the ion exchange process in the water softener system.

If your hard water supply is becoming an inconvenience, you can rest assured that there is an efficient water to settle the issue. Resin beads are designed to carry out an ion exchange process to remove the hard minerals and hardness ions from the hard water. In this article, we will take a brief look at water softener resin, its nature, types, the best resin for water softeners, and more.

3 Key Takeaways:

๐Ÿ”ธ Water softeners are designed to carry out an ion exchange process to remove the water hardness ions from hard water.

๐Ÿ”ธ Resin beads are of different types depending on their fucntion and purpose.

๐Ÿ”ธ General Technologies Premium Grade Resin is the best resin for water softeners that offers exceptional kinetic behavior, good physical, chemical and thermal stability, and more.

What resin is used in water softener?

The ion exchange process that takes place inside the water softener is handled by the resin beads. The exchange of hardness ions, calcium and magnesium, for sodium ions, takes place in the resin bed.

Polystyrene-type gel resin beads is the common type of resin beads using in water softeners. The size of each resin bead of this type ranges from 0.3-1.2mm. It is very porous skeletal structure that contains approximately 45% moisture. Polystyrene and Divinylbenzene (DVB) are the building blocks of this type of resin beads.

What is the best resin for water softeners?

Premium Grade Strong Acid Cation Exchange Resin from General Technologies is the best water softener resin available in the market. Although most cation exchange is 8% cross linked, the Premium Grade Strong Acid Cation Exchange Resin is 10% cross linked. This ensures longer lifespan, chemical, and chlorine resistance. This high capacity and high grade resin beads complies with the U.S. Food & Drug Administration. This makes it safe or use in the treatment of foods for human consumption.

If you are looking to replace the resin beads in your water softener, the General Technologies C110DQ cation resin is indeed the best choice. Its excellent hydraulic characteristics for optimal flow rate and backwash flow rates, makes it a reliable choice. The exceptional kinetic behavior, good physical, chemical and thermal stability of the General Technologies C110DQ cation resin comes from its high capacity and porosity. This also has the ability to fucntion in a wide range of temperature and pH conditions.

Where to buy water softener resin?

You can purchase water softener resin from any outlet of a reputable manufacturer or from online stores. Ensure the brand has a history of manufacturing high capacity and high quality resin beads.

How to drain a water softener resin tank?

Draining a water softener resin tank is simple. it consists of just a few steps and requires very less items to complete the task.

Step 1: Make use of a bucket

The first steps requires a bucket. You simply have to place the bucket under the resin tank to collect the water.

Step 2: Make use of a wet-dry vaccum

Another effective alternative tok the bucket is a wet-dry vacuum that can collect the water. Ensure the vacuum type is suitable to handle wetness.

Step 3: Shut off water supply

The next step is to turn off the resin tank’s water supply. The water supply to the resin tank is via a valve on the pipe. Turn off this valve to stop the water flow to the tank.

Step 4: Drain valve

Located at the bottom of the resin tank, you will find the drain valve. This valve must be opened to drain the water out. The drain valve can be closed once all the water has been drained out of the tank.

Does non-salt water softener have resin?

Yes, a non-salt water softener system will also have a tank of resin in them. It is quite similar in design and fucntion to a regular water softener tank.

How long do water softener resin beads last?

On an average, water softener resin beads are designed to last upto 10 years. However, one must remember that the lifespan and durability of resin beads in the water softener system depends on the nature of water and its quality.

If your water supply has high levels of chlorine, iron, and hardness ions; the ion exchange process and removals of hard minerals from the hard water is going to wear out the resin media and resin beads. In such cases, the resin beads or resin media in the water softener system might require a filling sooner than 10 years. One might have to replace the old resin beads with new water softener resins once in every 5 years if the chlorine and iron content in water are quite high.

Frequently Asked Questions:

1. What happens when water softener resin goes bad?

A damaged resin med or resin bed can be easily identified. If your high capacity water softener system that was performing well has stopping putting out soft water as it used it, it denotes that your water softener resin beads have gone bad. If you notice that your water softener system has started to run out of soft water quickly, it is time to for a regeneration process.

2. What are different types of water softener resin?

There are different types of water softener resins. The common 4 types are:

  • Strong Acid Cations โ€“ (SAC)
  • Weak Acid Cations โ€“ (WAC)
  • Strong Base Anions โ€“ (SBA)
  • Weak Base Anions โ€“ (WBA)

3. Is water softener resin biodegradable?

No. water softener resin beads are not biodegradable. As time goes by, water softener resin beads might break down, but they will not dissolve or degrade. Although resin beads are non toxic, they consist of several chemicals that require safe disposal. Therfore the exchangeable ion of the functional groups must be opted for safe disposable due to the insoluble and non-biodegradeable nature of the water softener resin.

4. How to dispose of water softener resin?

Resin beads that have been subject to the ion exchange process must be disposed of safely. They cannot be dumped as landfill, owing tot the strong chemical content and non-biodegradable nature. Inorder to dispose them, they can be sent to government approved Common Incineration facility that is in compliance with the Incinerator norms as per government environment protection Rule.


That’s a wrap on the article. We trust this brief discussion on water softener resins served helpful. Remeber to inspect the resin bed and quality of the water softener installed to keep track of its performance and efficiency. Replace resin beads in your water softener tank or initiate a regeneration process when necessary to enjoy seamless supply of soft water.
