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.

Qwik-Zyme L is the best option for speeding the breakdown of Fats, Oils, and Grease in anaerobic digesters. This customer operates a digester with feedstock composed of food waste and manure. The manure has a great stabilizing effect on the digester, but anytime the food waste fraction rises the digester begins to have issues like foaming.

The first thing they notice when too much fat has entered the digester is a rise in volatile acids.
To combat this jump, they meter in Qwik-Zyme L. The catalysts in Qwik-Zyme L speed the digestion of grease and fatty acids. This year they have begun adding Qwik-Zyme L 5 days per week as a preventative maintenance program.

The operator says “Anytime I see an increase in the VA:Alkinity ratio, I just increase the Qwik-Zyme L dose and watch the VA’s come back down.”

Qwik-Zyme L

WORKS FAST. Lipid-degrading biocatalysts that break down grease and long chain fatty acids that can build up in anaerobic digesters and cause foaming. Use whenever a load of high FOG feedstock is added, or whenever fatty acids are building up in the digester.
