Background

A municipality faced high cleanout costs for a sewer line connected to a shopping center. Due to excessive FOG buildup, the line required cleaning every eight weeks, leading to frequent maintenance and increased expenses.

Application

To address this issue, the municipality implemented BioEase 4260 Slow Release Block. As a slow-dissolving solid block, BioEase 4260 Slow Release Block is easy to apply—provided in a mesh bag, it is lowered into the water and suspended in the flow, lasting up to one month.

To evaluate its effectiveness, a trial was conducted:

• The upstream section remained untreated.
• The downstream section was treated with BioEase 4260 Slow Release Block.

Results

After sewer jetting, a significant FOG hot spot was identified in the targeted section of the pipe. Within just five weeks, untreated areas experienced substantial grease buildup, confirming rapid reaccumulation. However, the sections treated with BioEase 4260 Slow Release Block showed significantly lower grease accumulation over the same period.

By continuously monitoring the treated area, the municipality determined that the cleanout cycle could be extended from two months to seven months—an improvement of five months. This reduction in FOG buildup directly lowered maintenance frequency and operational costs.

Conclusion

With easy application and measurable results, BioEase 4260 Slow Release Block proved to be the best bioaugmentation treatment option, delivering:

• Lower operating costs
• Improved system efficiency
• Simplified maintenance and operations
