Liquid oxygen source to combat odors & prevent D.O. filaments

  • Fight low D.O. filaments
  • Can be added to any low oxygen environments
  • Reduces odors related to septicity and increases oxygen reduction potential (ORP)
  • Improves poor settling related to poor oxygen levels


OxyFresh is a liquid source of oxygen that helps to eliminate the low DO (dissolved oxygen) conditions, odors, and septicity. These conditions can occur in collection systems as well as activated sludge plants and aeration basins. A lack of dissolved oxygen can lead to bulking filaments, like Thiothrix/Type 021N, H. hydrossis, Sphaerotilus natans/Type 1701, and other filaments with sulfur granules. Odors caused by low DO can occur in collection systems as well as in lagoons, especially during the warmest months.

OxyFresh helps to adjust the ORP, offsetting septicity and promoting metabolic activity of aerobic bacteria. Simply inject OxyFresh into the basin when you need it most (during periods of overloading or hot weather). The plant will recover from low DO faster and have fewer odors with OxyFresh. Blended into OxyFresh are odor neutralizers that knock out offensive odors.

OxyFresh is often used in lift stations as well. OxyFresh will prevent downstream odors.

Case Studies

6 Acre Lagoon


Dave and Mike operate a 6 acre pond system in a town noted for its famed Italian restaurants. They have a manufacturer in town that produces frozen dinners and the manufacturer’s discharge is about 110°F. These high temperatures create low D.O. conditions that cause odors in the collection system and lagoon. The Italian restaurant was also sending a lot of cheese waste to Dave and Mike.


VitaStim Sludge Reducer was added into the lagoons and OxyFresh was metered into their system.


VitaStim Sludge Reducer lowered sludge production and OxyFresh eliminated their odor problem.



A municipal wastewater treatment plant was having difficulty getting good dissolved oxygen levels, especially during the hot summers. The low dissolved oxygen was causing severe filaments, poor settling, and odor problems.


The plant added 10 ppm of OxyFresh into the aeration basin.


They immediately noticed a difference. There were fewer odors and the filaments gradually went away and the settling improved. This city has used this product since 2008 and every year during the peak of the summer they turn to OxyFresh. OxyFresh provides their plant with better settling and fewer filaments.

Rendering Facility


A rendering facility suffers from bad hydrogen sulfide odors coming out of the force main into their plant. The sulfide levels were 30 ppm to 40 ppm. In addition to the bad H2S odors they run very low dissolved oxygen levels in their wastewater plant in the summer.


They injected OxyFresh at a rate of 2 ppm. The unique formula in OxyFresh not only controls H₂S but improves dissolved oxygen transfer which then reduces filaments.


OxyFresh successfully removed the sulfide odors, lowered their sulfide levels to less than 5 ppm, and helped settle the plant during hot summer days. Graph in New Window
