Efficient Air Saturation for Superior Flotation Performance
The Pan America Environmental RSS (Recycle Saturation System) is a proven, reliable recycle saturation solution designed specifically for Dissolved Air Flotation (DAF) systems. It delivers highly effective removal of solids, oils, fuels, FOG, and other contaminants across a wide range of industrial wastewater applications.
Recycle Saturation System Product Overview
The RSS series provides pressurized recycle water saturated with air (or nitrogen) for integration with new or existing DAF systems. It is ideal for retrofit applications or new builds where high-efficiency flotation is required.
By recycling treated effluent, pressurizing it, and supersaturating it with air, the RSS releases microscopic bubbles that attach to contaminants, causing them to float rapidly for easy skimming. This results in clearer effluent, higher contaminant removal rates, and optimized DAF performance.
Key Features & Benefits
- Proven advanced recycle design for maximum reliability and ease of maintenance
- Wide flow range: 5 to 2500+ GPM (custom multiples available for higher flows)
- Durable construction: Coated carbon steel, 304 or 316 stainless steel
- High-efficiency saturation: Higher pressure with optimized air transfer for excellent mass transfer and bubble formation
- Compact footprint with small saturation vessels
- No air compressor required in standard configurations (uses pressurized air source)
- Highly customizable: Numerous integrated options, controls, and configurations
- Easy integration: Ideal for retrofitting existing DAFs or API separators
- Robust components: High-head recycle pumps, NEMA 4 controls, pressure gauges, rotameters, safety valves, and more
Additional Standard Features
- Automatic equalization controls (Auto-Q)
- Inlet mixing chamber
- Pressure relief, vent valves, and isolation valves
- TEFC motors
- Lifting lugs and more
How the Recycle Saturation System Works
- Treated effluent is drawn from the DAF tank outlet.
- A high-pressure recycle pump sends it through a saturation vessel where air is injected and dissolved under pressure.
- The supersaturated water is released into the DAF inlet mixing zone.
- Pressure drop creates millions of tiny air bubbles that attach to contaminants (solids, oils, FOG).
- The aerated mass rises quickly in the quiescent flotation chamber for removal by skimming.
This process achieves superior flotation with lower air volumes and higher efficiency compared to traditional methods.
