INNOVATIVE WATER & WASTEWATER TREATMENT

Heron Innovators, Inc. manufactures Suspended Air® Flotation (SAF®) water treatment systems. SAF® is flotation without dissolved air®. Performance is not limited by changing conditions (e.g. gas solubility, pressure, temperature, etc.) and the physics that constrain traditional process systems, such as dissolved air flotation (DAF), induced air flotation (IAF), Induced Gas Flotation (IGF), enhanced clarification, cavitation air flotation (CAF), and other micro-bubble generators. As Heron customers say, “It just always works.”

Common Uses For SAF®:

  • Algae and Silt Removal
  • Biosolids Removal & Thickening
  • Enhanced Clarification
  • Filtrate Clarification
  • Oil/Water Separation
  • Primary/Secondary Treatment
  • Surface Water Treatment
  • Wastewater Reclamation

Suspended Air® Flotation (SAF®) uses charged micro-bubbles, called Aphrons, that attract, attach to, and encapsulate solids to make them buoyant.

SAF® consistently achieves higher Total Suspended Solids (TSS) removal than conventional flotation systems, even under variable influent conditions.

SAF® systems handle high loading rates in a smaller space, reducing OP/EX and enabling easy integration into existing flotation water treatment systems. These systems are known as conversions.

The Model EWP is a heavy-duty spiral press engineered to wash, dewater, compact, and transport screenings—delivering material to a conveyor, container, or other discharge point with dependable performance day in, day out.

It features a stainless steel press body with separate washing and dewatering zones. A hollow-shaft spiral, complete with internal perforations and a trailing nylon brush, injects wash water from the inside out and scrubs debris clean. A gasket-sealed, latch-ready stainless drain pan ensures easy access and hassle-free maintenance.

Through a cycle of forward and reverse spiral motion—repeated at least four times—the press removes up to 90% of organic content from screenings. The result? A dramatic 70–85% reduction in material volume from inlet to discharge.
