SAF® Drinking Water Treatment

Potable Water Treatment with Suspended Air® Flotation

Clear Water Starts with Better Pretreatment

Heron Innovators’ patent pending Suspended Air® Flotation (SAF®) is redefining potable water pretreatment. Engineered for efficiency and reliability, SAF® delivers high-performance clarification of surface waters by removing algae, silt, and other solids—before they reach downstream filters.

Why SAF® for Drinking Water?

✔ Enhanced Filter Performance
By removing problematic solids early in the process, SAF® extends filter cycle times and improves overall plant efficiency, lowering operational costs.

✔ Algae and Silt Removal
Whether you’re dealing with seasonal algae blooms or high turbidity events, SAF® delivers consistent removal of surface water contaminants that can overload traditional systems.

✔ Closed-Loop Treatment
SAF® is also ideal for treating filter backwash / reject water, enabling greater water recovery and overall system efficiency.

✔ NSF/ANSI – 60/61 Certified
SAF® is certified safe for drinking water contact.

SAF® Applications Include:

• Surface water pretreatment
• Algae bloom mitigation
• Silt and sediment removal
• Clarification of filter reject / backwash streams

With a small footprint, low chemical demand, and unmatched solids capture, Suspended Air® Flotation is the sustainable solution for municipalities and private utilities aiming to deliver clean, safe drinking water—while optimizing treatment performance from start to finish.
