Case Study: American Bottoms

Overview

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.

Challenges

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.

Solution

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.

Outcome

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.
