Oxidising biosides
After reading this article you will..
- understand the difference between oxidising and non-oxidising biocides.
- learn that the oxidixing biocides are nowadays very common in paper machine microbe control.
- learn that hypochlorite is the most common oxidising biocide. In several applications its efficacy can be improved by use of a stabiliser. Performic acid is a new and environmentally sound option.
