A feasibility study of fluidized bed high rate - biological waste treatment was performed. Goals of the , investigation were to demonstrate possible advantages of higher treatment rates and compaction of effective reactor volume, and to compare this, system to conventional high rate treatment, in particular, activated sludge.

This system was found to be capable of achieving high rates of Boo 5 removal, producing a, consistent low concentration effluent. Such treatment could be realized in one-fifth the reactor volume required for conventional activated sludge, operating at an equivalent organic loading rate. Less sludge wasting occurred in this system operation than is common for activated sludge and the sludge exhibited good settling characteristics. Operation of the system was troublesome adding variability to the data obtained. Although the effects of shock loading per se were not observed the system stabilized rapidly to process upsets.

Thus, the fluidized bed system has demonstrated significant advantages in high rate treatment and should be considered seriously as the need for high rate systems becomes more critical.
