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.

Clean UV Disinfection Room
Secondary Clarifiers

This covered UV Disinfection room looks beautiful now, but for a long time it was always covered in midge flies. The flies started their life cycle farther up stream of the UV process, primarily developing in the plants secondary clarifiers. There the redworms would feed on the mixed liquor, and grow in size and strength. As the redworm life cycle continues, the larva pupates into the midge fly. Many of these flies were coming up in the UV room. The operators were constantly cleaning the room, and had installed bug zappers and bug bombs to try to control them. Unfortunately killing the adult flies did no good as new ones were constantly developing in the clarifiers.

One day their local Rural Water Association circuit rider recommended they call Aquafix. We discussed their situation, and the configuration of their 6.5 MGD daily average flow treatment plant. They began using AQUABACxt , and Bug JuiceAQUABACxt is a biolarvicide that is very specific in its targets.They liked that it doesn’t harm the good bacteria, and doesn’t result in any effluent toxicity issues. Bug Juice is used to help degrade the protective cocoons that some redworms use to protect themselves. The combination was extremely effective and now they have a UV building that’s not a nightmare to spend time in.
