350 Tons of Material Removed from Basins in Central Florida

Wastewater Visibility News

A Challenging Environment Calls for Skillful Pros In Central Florida, a 12 MGD reclamation facility was experiencing a loss of capacity in their north aeration and anoxic basins.  These tanks presented a challenge because they were lined with rows of diffusers that circulate oxygen feeding the microorganisms and bacteria residents that break down the waste.  This job required experienced professionals to access and remove the built-up material, so the customer called on U.S. Submergent Technologies (USST) for a solution.  USST has cleaned tanks, pipes, and lift stations on over 400 projects around the United States.  Our qualified crews know how to evaluate situations on the ground to get the job done safely and efficiently. “I am proud of our guys for navigating the hard-to-reach environment along the bottom of these tanks and capably removing large amounts of material,” said Eric Pace, Foreman at USST.  “Our patented equipment and thorough safety measures allowed us to get into these structures and complete the job safely without any incidents.” At USST, safety is our number one priority, and these structures were vast in size and 20-feet off the ground.  By executing a site-specific health and safety plan, our crews implemented confined space entry protocols, air quality monitoring, and other required safety measures to move in and out of these structures expeditiously.  USST’s versatile Combination3® Truck has a powerful vacuum that allowed the crew to reach and dispose of a total of 350 tons of sand and grit material.  To learn more about how USST can restore capacity and flow at your facility call 844-956-1129 or email info@ussubmergent.com.  If you’ve got grit, USST can Grit ‘Er Done!®.

63 Tons of Material Removed from Rural Treatment Plant

Florida Sand and Grit Grant Program Reimburses Restoration Costs A rural community located in Southeast Florida’s Treasure Coast was experiencing capacity issues with their wastewater treatment plant’s multi-tank.  Specifically, inside their chlorine contact chamber, which disinfects and treats the wastewater.  A considerable amount of debris was clogging up this structure and decreasing efficiency at the plant. This municipal wastewater treatment plant collects and treats more than 500,000 gallons of wastewater per day and met the qualifications for reimbursement through Florida’s Sand and Grit Grant Program, which makes it possible for publicly owned facilities averaging 3MGD or less to address the

977 Tons of Sand Removed From EQ Tank

A Massive Job Calls for USST’s Expert Knowledge A large primary clarifier serving as an equalization tank at a city’s wastewater treatment facility had accumulated 16-foot-high mounds of sand along the bottom, seriously reducing its capacity and potentially passing grit through the treatment process.  U.S. Submergent Technologies’ (USST) expertly trained crew set about to handle cleaning this massive 125-foot in diameter structure.  “Our knowledgeable crews have a proven keen ability to navigate obstacles on the ground and this job presented some unique challenges,” said Paul Del Favero, Operations Manager at USST.  “This tank was huge, it’s covered, and the walls

Probing vs Complete Visibility Inside Wastewater Tanks

SediVisionTM Reveals Over Three Times The Amount Of Material Than Estimated In central Florida, a wastewater treatment facility was experiencing loss of capacity and inefficiency with one of its aeration basins.  They probed this 140 by 40-foot digester from a few accessible spots along the walkway and hit concrete every time, indicating minimal material buildup.  However, the aeration basin was still using more energy than required and seemed to be suffering from a loss in capacity.  This facility could not logistically drain this tank down and wanted to know precisely what was occurring under all that dark water.  U.S. Submergent

364 Tons of Material Removed from Town’s Wastewater Plant

USST Crew Responds to Changed Conditions Adeptly In rural Northeast Florida, a municipal wastewater treatment plant operating at .4 MGD was reaching critical capacity loss with their surge tank.  This large multi-chamber tank, which is essential to the overall health and functionality of daily operations at the plant, required cleaning.  U.S. Submergent Technologies (USST) was called in to assess the structure and remove the buildup of sand and grit throughout this wastewater tank. “This project was estimated to have 36 tons of material in the tank, but once we got on-site, we were dealing with at least seven feet of

Case Study: 630-Tons of Sand & Grit Removed from Oxidation Ditches

Florida Sand and Grit Grant Program Covers Restoration Costs PROBLEM: Two oxidation ditches at two wastewater treatment plants serving the City of Mount Dora were due for cleaning, having accumulated a significant amount of sand, grit, and debris over 15-years. This loss of capacity was increasing energy costs and reducing efficiency at these treatment plants. U.S. Submergent Technologies’ (USST) knowledgeable crew was called-in with our versatile Combination3® Truck, able to handle multiple setups to complete these projects. SOLUTION: A large oxidation ditch measuring approximately 50-feet wide by 330-feet in length was the first structure our crew tackled. While this oxidation

You May Have a Sand Problem and Not Even Realize It

Identifying and Managing Annual I&I Issues Where does the sand in wastewater treatment plants come from?  The answer is the collection system.  Determining whether or not there is an I&I (inflow and infiltration) issue can be the real challenge.  Spring is just around the corner, and with it, the time of year when most of the country’s rainfall usually occurs.  Throughout the wet season, an increase in flow into a WWTP can be due to inflow and not an increase in domestic wastewater collected.  Increase in flow is also a potentially a reliable indicator that treatment capacity has been compromised and may

USST: Safer, Quicker, Cheaper, Stronger

  USST: Safer, Quicker, Cheaper, Stronger This week, U.S. Submergent Technologies is performing sand and grit removal from a wastewater treatment plant in Orlando, FL, which requires confined space entry. The USST crew is removing material from two clarifiers at the plant. Both are 120 feet in diameter and 16 feet deep. Approximately 120 tons of sand and grit has been removed from Clarifier 1. “We performed a confined space entry, which includes constant air quality monitoring,” said Paul Del Favero. “Fall protection is being used as well while on the catwalk inside the tank.” The crew began work on Clarifier
