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

Flotation Without Dissolved Air®: Charged microbubbles for enhanced removal of suspended solids in wastewater applications.

For over a century, various forms of Dissolved Air Flotation (DAF) systems have been employed for the removal of suspended solids, and fats, oils, and grease from wastewater. The amount of air that can be dissolved in DAF systems is limited by the laws of physics and...

80% shorter operation time & major OPEX savings—SAF at Sauk Centre delivers!
After replacing a 60 ft² DAF, the plant reduced thickening from 168 hr/week to just 32 hr, cut polymer use from 10.5 to 4.6 gallons/week, and increased sludge solids from 4.1% to 4.7%—all while capturing 99.7% of solids. Less time. Lower costs. Better results.

"The SAF operated... consistently at an influent flow rate of 150 gpm, though it was increased to 185 gpm to view the effect on the average solids loading rate was approximately 22 lb/sf/hr, with a high of 32 lbs/sf/hr without failure."
