The city hired a consulting...

An over-all improvement in the basin’s flow pattern is evident . Problem This southern pulp and board mill faced the problem of an aging aeration system in its wastewater treatment lagoon. Maintenance was getting prohibitive on the 50 hp (37 kW) & 100 hp (75 kW) slow speed surface aerators, totaling 1,200 hp. `New slow speed aerators were very expensive and maintenance was expensive,` said the technical superintendent. `We looked at high speeds because of price, but they didn’t have the agitation....

The zero effluent goal required the highest quality aerators Problem When designing its new mill and wastewater treatment system in 1992, this Canadian Company had planned to discharge into a nearby creek. But, sensitive to the region’s pristine environment, they decided to design the most advanced effluent treatment system conceivable: a chlorine-free, closed loop, zero effluent treatment system using evaporation. The mill needed a quality aeration system to match its superior standards. Solution The...

The AIRE-O2® aerators maintain good effluent dissolved oxygen residuals Problem In December of 1987, this paper and board mill developed a load problem requiring immediate action: improve wastewater treatment efficiencies fast or slow down mill production to prevent a discharge violation. A slow down would result in significant revenue loss. The southern USA mill’s superintendent said, `we needed installed oxygen quickly.` Solution The AIRE-O2® aspirator aeration system was chosen to boost the...

Problem In 1986, this southern USA fine paper mill developed problems on start-up from a Christmas shut-down, requiring quick action to add efficient aeration to its 38 MGD (143,830 m 3) flow. Poor winter treatment, channeling throught the system, and high solids had also been problems. Since the company was committed to preserving the environment, it searched for the best aerators to meet its needs.
