Anion exchange resin beads are commonly used in water filtration systems today. These resin beads work to remove metal ions from water, making hard water softer and safer.

What are Anion Beads?

Anion beads are a type of ion exchange resin beads. These beads are typically made of resin material, round in shape, and have a gel-like structure.

They are brown in color with an average size of about 0.5mm. Anion resin beads are widely used in water treatment applications. When introduced into water, these beads can replace mineral ions and metal ions in water with harmless and safe mineral ions.

Anion exchange beads carry a negative charge (-). Examples include OH-, Cl-.

These products work to reduce the concentration of harmful metal ions such as bicarbonates, sulfates, nitrates, effectively softening hard water.

Characteristics of Anion Beads

Anion resin beads are made from polymer material due to the polymerization of styrene. Therefore, the interior consists of resins. This acts as an intermediary between the non-soluble polymer part and the three-dimensional structure of the resin with many cavities.

Anion beads have a diameter ranging from 0.5 - 1mm.

The initial color of the beads is usually light brown or yellow. After a period of use, the beads will gradually darken.

Anion exchange resin beads are round and tend to swell and increase in size when immersed in water.

Under ideal temperature conditions ranging from 20 - 50 degrees Celsius, the beads are highly activated.

Types of Anion Exchange Resin Beads

Strong Base Anion Beads

These are beads with strong alkaline properties. The most typical example is a 4th-degree amine like N(CH2)3-OH to disperse OH- in water.

These beads have the ability to absorb positively charged ion groups.

Strong base anion resin beads can be widely used in various water environments with diverse pH levels. To regenerate, a strong alkaline solution can be used.

Weak Base Anion Resin Beads

These are ion exchange beads containing weak base groups. Therefore, the ideal operating conditions are in neutral pH or slightly acidic environments. Regeneration may require NH4OH or Na2CO3.

Dual-function Anion Resin Beads

These are ion exchange beads containing both positive and negative ions. Therefore, they have the ability to remove harmful ions and impurities in water.

Advantages of Anion Beads

Anion resin beads have outstanding advantages such as:

Anion resin beads effectively remove harmful minerals, metal ions in water, especially calcium, magnesium causing hard water. This softens water and provides clean, safe water for users' health.

Anion resin beads soften water, preventing direct water-use devices from rusting, yellowing, and scaling. This helps to increase the lifespan of the equipment.

After a period of use, anion resin beads can be regenerated multiple times and reused. This helps to extend the product's lifespan and contribute to cost savings in using ion exchange resin beads.

The cost of anion beads is relatively low. However, the effectiveness in treating hard water is very high.

These beads are insoluble in water, thus not affecting the quality of the water source, being environmentally friendly and user-friendly.

Applications of Anion Resin Beads

Anion beads have a wide range of applications in various fields, including:

Purified water treatment systems for bottling and packaging.

Water softening systems for residential areas, buildings, villas, etc.

Used in water treatment systems for industrial production.

Water softening for industries like metallurgy, electronics manufacturing, mineral extraction, pharmaceuticals, and food processing.

Applied in wastewater treatment and reuse.
