An oxidation ditch at a Central Florida Wastewater Treatment Plant was in need of cleaning, having built up a significant amount of sand and grit.  The facility’s treatment process is comprised of a Type 1 Oxidation Ditch operating as a conventional activated sludge treatment facility measuring 320-feet by 70-feet.

USST Foreman, Michael Kisling, led the USST crew through the project from start to finish, utilizing the powerful Combination Truck and GritGone Process® to tackle the job. The truck’s extended boom and downhole pump were used to reach and remove sand and grit from the tank without having to perform a drain down.

“One of the advantages of our equipment that makes it so unique is that we can remove very large amounts of material while the whole facility remains in operation,” said Michael. “Plants don’t have to shut down or alter treatment flow, and we can reach and remove material quickly.”

Another advantage of using the Combination Truck to perform the cleaning is that confined space entry was not needed. The facility saves time and money by avoiding confined space work and crew members benefit from a lower risk jobsite.

With the GritGone Process®, the sand and grit is separated from the slurry for disposal while the water is returned to the oxidation ditch for treatment. USST can dispose of more material at a higher production rate without the added weight of water.

In total, approximately 402-tons were removed from the structure, the equivalent of 141 fully-loaded F-150 trucks!  The material was disposed of offsite, restoring much needed capacity to the facility.
