What Is Evolet Anti‑Scale Media?

n

Evolet anti-scale media uses a patented catalytic process to convert dissolved calcium and magnesium (hardness) into micro-crystals that remain suspended in the water. Unlike a water softener, Evolet anti-scale media does not remove the hardness minerals — it simply prevents them from forming sticky scale that clogs pipes or damages appliances. The Water Company

Because the media creates a “template” on its surface, it encourages stable crystal formation, which does not adhere to surfaces or plumbing fixtures. Rotea Australia

Key Features

n

n
• No salt, chemicals, or electricity needed.

n

• Long service life — the media does not require regeneration or backwashing.

n

• Upflow contact design maximises scale control efficiency.

n

• Maintains mineral content in water — calcium and magnesium remain in solution.

n

• Certified: WQA Gold Seal, tested for material safety.

n

• Nanostructured surface lowers the energy needed for crystal formation.

Benefits

n

n
1. Scale Prevention: Transforms hardness ions into stable micro-crystals, preventing scale deposit buildup.

n

2. Eco-Friendly: Since there’s no salt or chemical added, the media is more sustainable than traditional softeners.

n

3. Cost Saving: Without the need for regeneration, you save on salt, water, and maintenance.

n

4. Protects Appliances: Helps prevent scale in geysers, boilers, kettles, and plumbing.

n

5. Simple Operation: No power or backwash makes the system easy to maintain.

Ideal Applications

n

n
• Home plumbing systems (to protect pipes and water heaters)

n

• RO feed water (to reduce scale risk on membranes)

n

• Boiler systems and heat exchangers

n

• Aquaculture and industrial processes where scale buildup is costly

n

• Appliances such as kettles, coffee machines, or shower systems

How to Use / Install

n

n
• Install Evolet anti‑scale media in an appropriate media vessel or cartridge housing.

n

• Ensure an upflow water direction to maximise contact with the media.

n

• No regeneration needed — simply replace media when contact capacity is exhausted (based on manufacturer guidance).

n

• Check periodically for media condition, especially in high-hardness environments.

n

n

Safety & Maintenance

n

n
• Since it’s a non-chemical solution, Evolet media does not leach dangerous substances into drinking water.

n

• Store media in a dry place to avoid contamination before use.

n

• Flush the system after installation to remove any loose particles.

Physical Properties & Operational Conditions of Evolet Anti‑Scale Media

n

Based on the SC3 Evolet Media specification sheet from Rotek / RoteK Australia: Rotea Australia

n
n

n
• Bulk Weight / Density: ~ 750 kg/m³.

n

• Specific Surface Area: ~ 270 m²/g.

n

• Colour: Light yellow.

n

• Mesh Size / Particle Size: 0.5–0.8 mm.

n

• Moisture Content: ~ 24–28%.

n

• Freeboard (Up‑Flow): 60–70%. (Freeboard is the portion of the vessel not filled with media, allowing for expansion/contact)

n

• Operating Temperature Range: 5 °C to 70 °C.

n

• pH Range: 6‑9 (for effective operation, according to spec sheet).

n

• Volume Change in Water: Maximum ~ 60%. (This presumably refers to expansion or swelling when the media is in contact with water.)

n

• Media Lifetime: 2–3 years (as stated in the spec sheet) under normal usage.

“Exchange Capacity” / Scale-Crystallization Function

n

n
• Unlike traditional ion-exchange resins, Evolet doesn’t “exchange” ions in the sense of swapping Ca²⁺ or Mg²⁺ for Na⁺. Instead, it promotes the formation of stable micro-crystals of calcium and magnesium (hardness minerals), which remain suspended rather than forming scale that adheres to surfaces. Rotea Australia

n

• The media acts as a template: hardness minerals crystallize on the surface of the media, but once they reach a certain size, these particles detach and remain in the water as harmless, stable crystals. Rotea Australia

n

• Because of this mechanism, there is no classical “ion exchange capacity” (meq/g) listed — instead, the capacity is more about how much scale-precipitable hardness it can manage over time. The spec sheet does not provide a direct “exchange capacity” in meq/L.
