Mohneesh Kalwani a very good question and I can answer this by: BG 11 +N media is a nutrient-rich growth medium for microalgae, typically used in laboratory settings. When added to wastewater for microalgal growth, the following changes can occur:

1. Nutrient enrichment:

2. pH adjustment:

3. Increased turbidity:

4. Microalgal growth promotion:

5. Changes in wastewater composition: The media can alter the chemical composition of the wastewater by:

- Increasing nutrient concentrations (e.g., N, P, K)

- Introducing new ions or compounds (e.g., micronutrients)

- Potentially changing the carbon-to-nitrogen (C:N) ratio

Further I can ellobarate each n every point for better understanding if required as well

Thank you sir for your response could you please let me know how much does the nutrient concentration changes? What about its COD, BOD etc?

Awaiting for your response sir

Mohneesh Kalwani the change will dipend on the original wastewater compostion and on the wastewater:BG11+N volume ratio...
