The OSSI JET unit is an oxidation system comprised of a submergible electric pump, an air suction tube and a certain number of ejectors. The sewage that is pumped through a nozzle captures air at atmospheric pressure through a tube by the Venturi effect, generating a flow that is heavily mixed with air by means of the ejectors.
These appliances guarantee an elevated oxidation output, with the possibility of conveniently directing the flow to improve homogenisation of the sewage.
The primary liquid flow, generated by an electric submergible pump, passes through the calibrated nozzle, the suction area of the secondary air flow and exits through the mixing tube and the diffuser. The primary flow, passing through the nozzle, considerably increases its speed creating a stable vacuum condition in the suction area with the subsequent suction of air. The water (the primary flow) and the air (the secondary flow) are then completely mixed together by passing through the high turbulence areas of the ejector(s).
