The technology uses two phase jet nozzles to supply atmospheric oxygen to recirculated liquid in a proprietary mixing system. Recirculated liquid is pumped through the inner, primary nozzle creating a high velocity liquid stream while air is fed into the secondary outer nozzle. The high velocity liquid stream shears the air into a turbulent, fine dispersion of gas and liquid.Mass Transfer SystemsFall River, MATel: 508-679-6770Web: www.mtsjets.com
