90-Tons Removed from Aeration Basin
RAG & GRIT REMOVAL IN SOUTHEAST, FL
An aeration basin at a Southeast Florida Water Reclamation Facility was experiencing reduced capacity and due for maintenance. Measuring 206-feet in length and divided into eight 24-foot by 24-foot cells, the cleaning of the tank was part of a rehabilitation plan to repair and replace key components of the structure.
U.S. Submergent Technologies’ (USST) Field Supervisor, Paul Del Favero, arrived with a team to the site prepared to perform rag and grit removal services. In order to effectively remove the large quantities of sand, grit and rag material from the aeration basin, a drain down was necessary. Once the tank was drained, the USST crew came in and vacuumed up the material and performed manual rag removal from the fine bubble diffusers.
“Our Combination3® truck sports a vacuum powered by a blower capable of delivering nearly double the CFM of a standard vacuum truck,” Denver Stutler, USST’s CEO, said, “allowing us to remove large amounts of dry material and complete the job quickly. It’s not your typical vac truck.”
Applying their confined space entry training and expertise, the USST crew removed more than 90-tons of total material from the aeration basin and disposed of the material offsite. Workers were then able to access, repair, and replace components on the bottom of the cleaned structure.
“I knew our reliable equipment and exceptional crew would be able to get the job done quickly and on schedule,” said Paul.
Specializing in hard-to-reach environments in wet or dry conditions, USST can build a plan to safely and efficiently remove material from tanks, pipes, lift stations, and more.
