Industrial wastewater often contains large amounts of organic matter (BOD, COD).This can be removed by a biological wastewater treatment process assuming, that there is the sufficient amount and the proper type of nutrients available, along with other factors that influence the process’ biology. If your biological wastewater treatment process is not performing, it is critical to target and fix the root cause: your system’s microbial community.
Industrial wastewater often lacks sufficient amount of nitrogen (N) and phosphorus (P) nutrients for microbial communities to achieve the biological activity level required for biological purification. It is therefore necessary to add extra nitrogen and phosphorous to get the process to work properly.
This depends on variable such as your purification process type, system size, system load compared to the dimensioning, dosing equipment available, etc.

Yara delivers the nutrients you need.
There are many factors that influence the optimal biology in a biological purification process. One of the most important factors is the availability of nutrients. What is the right amount of nutrients for your process? This depends on the amount of organic material that is biodegradable and on your system's operating conditions.
Biological wastewater treatment problems commonly related to:
|insufficient nutrients||too much nutrients|
Industrial wastewater can vary greatly in both ints composition and its need for the addition of external nutrients. Municipal wastewater usually contains more than enough nitrogen and phosphorus for optimal biology.
The following industry sectors produce effluents that may need the addition of external nutrients to a greater or lesser extent:
