Biocides in Food Processing Wastewater
- Increased TSS in effluent
- Poor settling
- Poor removal of nutrients
A common concern among the operators of food processing wastewater plants is upsets from something in the influent. Biocides like Quaternary Ammonium compounds (Quats) are a common cleaning component used to disinfect the equipment at the facility. Cleaning crews washing these compounds down the drain and can cause upsets to the treatment plant down stream. These upsets can take the form of poor settling, increased TSS in effluent, or inability to build mixed liquor and subsequent poor removal of BOD and nutrients.
