VACUUM AIRLIFT™

Searen's Vacuum AirLift™ (VAL™) is the only water treatment technology  that offers superior biomass management via water circulation, fine particulate extraction, and gas exchange while reducing capital expenditures and operational costs

“THE VAL™ IS THE ONLY SYSTEM I'VE SEEN YET TO ACCOMPLISH ALL THREE FUNCTIONS:

1. WATER CIRCULATION, 2. CO2, N2 & O2 MASS TRANSFER

AND 3. PARTICLE HARVESTING." 

Peter Lammers - Arizona State University Research Professor

 
 

VAL's™ efficiency, effectiveness, and capacity enable fish farms to operate at higher biomass throughput, with higher biosecurity.

A Dissolved Gas Stripping Tower  

Providing highly effective dissolved gas stripping via vacuum extraction. Per Henry's law of dissolved gas solubility the stripping power is amplified by the ratio of atmospheric over vacuum pressure. Undesirable dissolved gases such as carbon dioxide, nitrogen, hydrogen sulfide and volatile organic gases are readily extracted.

 

A Gas Dissolution Device

Providing highly effective replacement of desirable dissolved gases. The down coming tube provides a counterflow arrangement with long residence time ensuring desirable gases are completely dissolved. Desirable gases such as oxygen, ozone, or carbon dioxide, depending on the application, are readily injected and dissolved in the process water stream.

A Foam Fractionator

Providing unmatched fine particle removal. The rising air bubbles in the VAL™ collect fine particles and form a foam at the top of the VAL™. This foam is then continuously vacuum extracted and captured for use or disposal as appropriate.

An Airlift Pump

Providing efficient water circulation device in low head applications. At low head, airlift pumps are more efficient than other pumping technologies.  

THE VAL™ IS

 

The VAL™ based Recirculating Aquaculture System (RAS) is simple, reliable, efficient, and sustainable.

Traditional RAS systems require

substantial gas stripping, aeration, particle

extraction, and HVAC subsystems

with multiple prime movers.

VAL™ based RAS reduces or eliminates auxiliary subsystems reducing complexity, physical footprint, and cost.
