RECIRCULATING AQUACULTURE OVERVIEW

A Revolutionary Solution

The revolutionary, patented, VAL™ is the sole aquaculture technology that improves the rate and simplicity of impurity removal through water circulation, fine particulate extraction, and gas exchange in one reliable, energy-efficient device.

 

Hugely important, it is the only multi-function unit delivering consistent results in a wide range of land-based aquaculture environments (shellfish, finfish, hatcheries, etc.).

Challenges Faced in Intensified Rearing Conditions

The high density rearing conditions in Recirculating Aquaculture Systems (RAS) present numerous challenges for farmers. The fish rapidly deplete the O2 supply while producing CO2 and solid waste quickly creating an adverse environment if not properly addressed. If left untreated this contamination leads to off flavor, bio-security issues and risk human health.

VAL™'s Value Add

The VAL™ is a highly effective tool in addressing water circulation, particulate removal, degassing, aeration and other aquaculture water management as well as bio-security issues. It's simplicity and efficiency reduce costs while its performance increases yield resulting in high return on investment and profitability. The VAL™ continuously extracts fine particulates and pathogens through foam fractionation. In addition, the VAL extracts CO2, N2, H2S and other undesirable dissolved gases while replenishing the O2 consumed in the rearing and denitrification processes.
