Avoid problems and ensure your wastewater treatment is performing optimally by creating the right microbial community.
Industrial wastewater often contains organic matter that needs to be removed. Biological wastewater treatment processes use bacteria to degrade and decompose these materials.
Biological treatment processes work efficiently as long as the right nutrients are available in adequate quantities to deal with the levels of BOD and COD (biochemical oxygen demand and chemical oxygen demand) in the wastewater – alongside the other factors that influence the process' biology.
Typical biological wastewater treatment problems commonly related to insufficient nutrients include:
Biological wastewater treatment problems commonly related to too-high nutrient levels include:
If your biological wastewater treatment process is not performing, it's critical to target and fix the root cause: your system's microbial community.
You are likely to find that your wastewater lacks sufficient nitrogen (N) and phosphorus (P) nutrients for the microbial community to achieve the biological activity level required for biological purification.
Adding nitrogen and phosphorous will get the process working properly – but avoiding over-dosing is crucial.
Achieving peak performance will depend on variables such as:
If you need help resolving the issues, you can rely on Yara's expertise, gained from over 100 years of pioneering nitrogen chemistry and more than 20 years' working with the wastewater treatment sector.
Our experts will work with you to find the best possible solution for your process and supply quality bio-nutrients reliably.
The right nutrient selection and correct dosage offer economic and process optimization benefits.
A wide variety of industry sectors produce effluents that may need the addition of external nutrients:
Municipal wastewater usually contains more than enough nitrogen and phosphorus for optimal biology.
