process requires that the aeration tanks be enclosed and gas-tight to
avoid loss of high purity oxygen to the atl~osphcre. For treatment
plants of the 60 NGD magnitude, it is necessary to provide on-site
oxygen production equipment.
While the process has been extensively tested in pilot plant and
full scale applications, it has not been operated on a long-term,
continuous basis. The process appears to be theoretically sound
but has not yet been conclusively proven for general application.

installation of 30 MCD UNOX aeration tanks in addition to the
