At Aquafix, our eagerness for fixing every problem in the wide world of wastewater means we encounter some of the strangest situations water can offer. In this new series, Unique Applications, we look at some of our most stand out issues and most inventive solutions.

In Spring of 2019, the Denver Metro Area water district contacted Aquafix about products for controlling BOD and TSS in lift stations. The district’s collections system effluent was treated by a separate entity, which meant the district paid surcharges based on the strength and quantity of waste discharged. BOD and TSS made up a combined 56.5% of the surcharges paid.

Aquafix recommended our lift station bacterial products: Bug On A Rope and GreaseZilla . A trial began in June of 2019, comparing discharge parameters prior to the trial with parameters taken after 2 months of treatment. Pre-treatment BOD averaged 677 ppm. This was dropped to 510 ppm in the first sampling after treatment. Likewise, TSS averaged 681 before treatment, and was dropped to 225 after treatment.

The decrease in these two parameters dropped the water districts payments by $72,517 versus the average projected payment prior to treatment.

Featured Products


GreaseZilla is a revolutionary new grease-digesting bacteria complex. It softens and removes grease, degreades grease on the walls, lowers hydrogen sulfide, and lowers BOD in collection systems. GreaseZilla is highly effective year-round.

Bug On A Rope

SET IT AND FORGET IT. Slowly releases powerful bacteria and nutrients for grease control. This unique formula binds together bacteria and biocatalysts with a slow release oxygen-rich biostimulant base. Far more powerful than netted “soap on a rope”.

This trial and technical memorandum was completed by BAI Engineers on behalf of their customer, a municipal district. The full report includes: 

  • Detailed data on BOD, TKN, and TSS before and throughout the trial
  • A breakdown of costs and savings from the product trial
  • Third-party recommendations to the municipal district, based on the results of the trial
