Lime is used in municipal waste water treatment to stabilize biosolids by killing pathogens, viruses and reducing vector attraction to produce high quality fertilizers for the agricultural industry.
- reducing biosolids odors and improving handling through drying.
- ensuring pH and alkalinity are correct to optimize biological treatment operations.
- adjusting pH and alkalinity to optimize coagulation and flocculation settling processes.
- Controlling nutrients like phosphorus, as lime precipitates phosphorous to very low levels without biological treatment.
