Wastewater Treatment Clarifier Cleaning

Within your municipal wastewater treatment facility, you might have primary treatment clarifiers to help remove the solids from the wastewater. There might come a time when you’ll need to schedule a clarifier cleaning.

“We will either get hired direct by the municipality or by the sandblasting contractor to vacuum and dispose the sandblasting media,” shares Jeff Dean, Advanced Waste Services Milwaukee General Manager

At that point, you’ll probably contract someone to sandblast the clarifiers to remove any deposit build-up and prep for a new surface coating. But you’ll also need someone to quickly remove the sand blasting media.

If your sandblasting contractor intends to hire the vacuum truck company that will remove the sand blasting material, get more information.  Why? Because you might be legally considered the generator of the sand blasting waste, since the project is done on your site in your water treatment clarifiers.

At that point you’ll want to know the record of the vacuum truck company, where the waste is being disposed and the record of the waste disposal company.  (We’ve made this easier at Advanced Waste Services, by providing both the transportation and disposal).

"The SuperSucker vacuum truck combined with vac boxes is the ideal solution for quickly removing sandblasting media offsite for disposal," shares Derrick Lancour, AWS, Results Delivery Specialist.

Getting back to the “more information.” It comes down to eliminating unnecessary costs and keeping the project on schedule. So here’s what’s important for you to understand:

What kind of Vacuum trucks will be on site? Vacuum trucks are not the same. You’ll want a truck specifically designed for sand and dry material. When we are contracted to vacuum sandblast media and dispose off-site, we bring the SuperSucker. The most powerful truck in our fleet and designed for sand. Bring the wrong truck and you’ll significantly delay the cleanup process – which adds cost and extends your completion time. This video below explains the differences of 3 vacuum trucks.

What is the disposal process? Besides knowing what type of vacuum truck will be onsite, you’ll also want to understand the disposal process, so you can keep costs down and the project on-time. Let me explain.

The best feature of the SuperSucker vacuum truck is its powerful vacuum on a short, easy to navigate chassis. The unfortunate downside of this, is its legal hauling capacity, and here’s why this is important to your project.

If you filled a SuperSucker tank, completely with sand blasting media, you might be illegally transporting on the road, since you’d probably be overweight, which results in violations, increases cost, delays projects and cause headaches.  So the SuperSucker, to comply with legal road hauling limits, would have to take several trips a day, back and forth, to the disposal site, with only a small load. Which is expensive.

“Using the SuperSucker to fill the vac boxes allows zero interruption. This keeps the project on deadline and keeps transportation costs down,” shares AWS Transportation Manager Drew Acklam.

So what’s the best disposal option to keep sandblasting team on schedule without being delayed by the vacuum truck going back and forth to the disposal site?

Arrange to have frac tanks or vacuum boxes aka vac boxes onsite. The SuperSucker will pump the sandblasting material into the vac boxes, which allows the project to go non-stop. When the vac boxes to frac tanks are filled, arrange for the vac boxes to be delivered to the disposal site – its that easy.

"Our goal is to avoid any delays to the sandblasting operation, by providing continuous vacuum and removal of the sandblasting material within the clarifier," shares AWS Project Manager Tony Pankow.

If it turns out that you are responsible for hiring the vacuum truck company to remove the sand blasting media, the same rules apply: What kind of vacuum trucks and what’s the disposal process.

So you can see the goal of this project is keep the cleaning project running without interruptions while also eliminating excessive and unneccesary costs.
