Why is it so important to control fats, oils and grease?

Qwik-Zyme L was tested against a control for a customer with COD issues. This testing showed a sharp decrease in COD when using Qwik-Zyme L, while the control was essentially at the same level after 4 hours. The control did see an initial increase in COD due to COD chains separating but not degrading and giving the appearance of more COD.
In the winter months, when water temperatures are colder, the naturally occurring bacteria cannot completely break down FOG and the fatty acids that build up in the wastewater plant. These fatty acids are then taken up by filaments like Microthrix Parvicella and Nocardia which allows them to float and foam. Qwik-Zyme L breaks up these fatty acids and cuts off the filament’s food source. It’s fascinating science for wastewater operators.
Qwik-Zyme L – Grease Degrader works well with VitaStim Low F:M and Foam Buster and is used in all types of municipal and industrial applications. For especially tough issues, use the synergistic combination of Qwik-Zyme L and Foam Buster. Foam Buster alters the bacteria populations so the foam will not return while Qwik-Zyme L helps to get the grease under control.
This product is either metered or poured into the front end of the wastewater process. Do not spray this product into the air.

Recipe for Nocardia Removal |
1.) Waste solids 20-30% (Example: if MLSS is 3000, waste to 2100-2400 ppm) |
2.) Add Qwik-Zyme L to the head of the plant (Double dosage if possible). This will heavily break down FOG for the bacteria to easily digest. |
3.) Add Foam Buster to the head of the plant or aeration basin (Double dosage if possible). This will activate and stimulate the bacteria to specifically break down FOG that is feeding the Nocardia. |
4.) Keep MLSS low for 2-3 sludge ages |
5.) After, rebuild the biomass |
(Optional: Add Bug On A Rope to lift stations to start the FOG degradation process sooner) |

We had a bad Nocardia break out in our SBR and it was hard to control. We heard about the Qwik-Zyme L biocatalyst, and it worked. It was like Wow the foam went right down. Potent stuff.
Joe –
The cheese plant really dumped on us and the plant foamed up. We used a bit of Qwik-Zyme L and it ate it up. Incredible.
