The Vacuum Airlift™ or VAL™ is a patented technology that simplifies and enhances water management in nearly every water treatment application.
The VAL™ utilizes a vacuum to power an airlift pump resulting in a highly efficient and effective device. It is the only aquaculture technology that improves water treatment through combined water circulation, fine particulate extraction, and gas exchange in a single device.
Sustainable Aquaculture, a water treatment solution utilizing Searen's VAL™, was attributed the “Solar Impulse Efficient Solution” Label - Validating high standards in profitability and sustainability.
To receive this Label, The Vacuum AirLift™ was thoroughly assessed by a pool of independent experts according to 5 criteria covering the three main topics of Feasibility, Environmental Benefits, and Profitability. All labelled solutions are part of the #1000 solutions portfolio that will be presented to decision-makers in business and government by Bertrand Piccard, Chairman of the Solar Impulse Foundation. The aim of this initiative is to encourage the adoption of more ambitious environmental targets and fast-track the implementation of these solutions on a large scale.
Innovative RAS Water Treatment
The intense rearing conditions in Recirculating Aquaculture Systems (RAS) present numerous challenges. Water quality management is paramount. Livestock rapidly deplete the Oxygen supply, while producing Carbon Dioxide and solid waste. These actions quickly create an adverse environment. If not properly addressed, it can result in poor flavor, not to mention illness and death of livestock.
Challenges in Intensified Rearing Conditions
The essential elements of RAS water management are water circulation, clarification, biofiltration, degassing, and aeration. They create an environment conducive to livestock health and growth by removing unwanted fine particulates, dissolved solids and waste gases produced by fish, while replenishing the Oxygen they consume in respiration.

HOW VAL™ WORKS
VAL™ is a multi-function technology that outperforms other systems by combining four functions that otherwise require separate sub-systems into a single, powerful device.
VAL™ is a Foam Fractionator
VAL™ provides unmatched removal of fine particles and pathogens.
Rising air bubbles in the VAL’s™ inner tube collect fine particles and form a foam at the top.
VAL™ collects this foam, which is then continuously vacuum extracted and captured for appropriate use or disposal.
VAL’s™ multifunction performance capabilities make it uniquely powerful for sustainable RAS water management. Use the links below for an overview of how VAL™ specifically applies to Aquaculture, Technical Papers, or to view the full video.
