AOX (adsorbable organic halogens) are formed by a chemical reaction from the pulp bleaching processes which use chlorine or chlorine dioxide as bleaching agents. Jet aeration systems produce acceptable AOX levels in the effluent. Efficient mixing results in low AOX effluent.

With the jet aeration system, both mixing and oxygen transfer can be independently controlled. Mixing is regulated by the recirculation pump. The level of oxygen transfer is controlled by the amount of air the blower releases to the jet aeration system.

Efficient mixing and oxygen transfer will yield an effluent which is non-toxic. When the wastewater is properly treated, 100% fish survival will occur in 100% effluent.

Jet aerators have been used in over one hundred pulp and paper mills. Jet aeration is a prevailing, proven technology that achieves high oxygen transfer efficiencies with minimum maintenance and minimum operator attention.

Jet aeration systems are designed for a twenty year life. These systems are designed so there is no need to drain the tanks for maintenance purposes. The pumps and blowers, which are generally the only components that require maintenance, are placed outside the tanks.
