The American Bottoms Wastewater Treatment Facility is a very large facility located in Sauget, Illinois. They can treat an average of 26-52 million gallons of wastewater a day of municipal and industrial water.
Heavy limescale formation on structures & equipment (from quicklime that is added to neutralize the water) were forming 8” – 10” thick. There were huge expenses from cleaning & disposal of the limescale on a weekly basis plus all of the downtime.
The SB-4000, SB-3600 and SB-2800 were installed on the two main water pipes (36” pipe) transferring the incoming wastewater to the process. One SB-2000 was installed on the lime recirculation line to treat the lime slurry.

Within the first month, scale formation slowed down dramatically, thus reducing the cleaning of the structures to a fraction of the time. The scale formation was much softer also. As an added bonus, they no longer needed to add polymers to the water saving more than $1,000 a month. The savings on cleaning, equipment repair, replacement, energy, water usage, manpower, downtime and use of a polymer is estimated at more than $100,000 a year.
