Polston Applied Technologies removed more than 35 cubic yards of accumulated material (sand and grit) from the bottom of our wastewater treatment plant while it remained in operation...
— Public Works Supervisor | Branford, FL
I am very impressed with their [equipment]. I would say they removed about 90% of the grit without taking my plant out of service.
— Superintendent of Water & Wastewater | Starke, FL
The demo that was performed worked well and removed a lot of grit in a short period of time, without impacting our process.
