How to Choose the Right Size of Aquavow Polyphosphate Antiscalant Balls

The size of Aquavow polyphosphate antiscalant balls should be selected based on your water treatment system type, flow rate, and installation location. The following guide helps you quickly choose the appropriate specification.

Antiscalant Ball Size Classification: 

Small Particles (1–2mm) have fast dissolution, ideal for small household water filters or pre-filters, and are best for systems with low flow rate and limited volume. 

Medium Particles (3–6mm) have moderate dissolution speed, suitable for whole-house water systems or medium-sized commercial systems, balancing lifespan and scale prevention performance. 

Large Particles (7–12mm) have slow dissolution, suitable for high-flow industrial or large commercial systems, providing long-term scale control and reducing maintenance frequency.

Practical Examples

1）Small Containers / Filter Cartridges:

Prefer small particles for even filling and complete dissolution

2）Large Tanks / Cylinder Systems:

Choose medium or large particles to ensure uniform dissolution and extend service life

3）Lifespan Considerations:

Small particles dissolve quickly, requiring more frequent replacement, Large particles dissolve slowly and last longer, but may dissolve insufficiently in low-flow systems. Regularly check the wear of antiscalant balls to maintain effective scale prevention

Surface Area and Dissolution Rate

Surface area refers to the area available per unit mass of material. Small particles have a larger surface area per unit volume, allowing more water to contact the ball surface. This enables polyphosphate to release faster, react with calcium and magnesium ions, and prevent scale formation more effectively.

Choosing the Optimal Size and Quantity

Different containers, flow positions, and system designs require different ball sizes and quantities to achieve optimal performance. While particle size and surface area provide a preliminary guide, the specific size and quantity should be determined based on your system characteristics.
