• AQUA BELLA quality, with sizing and installation support

Technical Specifications

How It Works: Treatment Stages

Water passes through the following stages in order. Each stage is arranged to protect the next one:

1. String-wound filter: Its layered winding traps sediment in depth; used as the first stage under heavy particle load.
2. 1 micron fine sediment filter: Captures fine particles that pass the previous stage, reducing turbidity and giving clearer water.
3. 5 micron sediment filter: Removes sand, rust, silt and particles larger than 5 microns, preventing early clogging of the following cartridges and tanks.
4. CTO carbon block filter: Compressed carbon block reduces chlorine, chemical residues, taste and odour, and also acts as an extra mechanical filter for fine particles.

When Is It the Right Choice?

• Periodic maintenance of 10″ four-cartridge well water systems.
• When cartridges change colour or pressure drops.

Choosing for Well Water

Besides hardness, well water may contain iron, manganese, turbidity and microbiological contamination. To choose the right stages, first measure your water hardness (how to measure water hardness) and ideally have a laboratory analysis done. If iron and manganese are high, suitable pre-treatment must be added before softening, as they foul the resin. Compare all options on our well water treatment systems page.

Installation and Maintenance

• Cartridges are usually replaced every 3–12 months depending on water quality and consumption; washable cartridges are cleaned periodically (when to replace a limescale filter).
• The AQUA BELLA team can support you with sizing, installation and commissioning.
