This water treatment plant in Ohio cleans its backwash settling basin twice a year. A sample of these iron and manganese residuals was sent to the WaterSolve, LLC lab where testing revealed it was a good fit for Geotube® dewatering. A 30′ circumference by 60′ long Geotube® was installed and the dry wt solids were 18% when they loaded and hauled them to the landfill.
