1.1 Advanced Biological Nutrient Removal (BNR) Systems:

UII's BNR systems utilize a multi-step approach to break down organic matter and remove nitrogen and phosphorus. Key components include:

• Aerobic Processes: This stage involves introducing oxygen to promote the growth of beneficial bacteria that oxidize organic matter and convert ammonia to nitrite and nitrate.
• Anaerobic Processes: In this stage, the absence of oxygen fosters the growth of denitrifying bacteria that convert nitrate to nitrogen gas, effectively removing it from the water.
• Phosphate Removal: Specialized bacteria can be utilized to remove phosphorus from the wastewater, leading to a significant reduction in nutrient levels.

1.2 Key Technologies Employed in BNR Systems:

• Moving Bed Biofilm Reactors (MBBRs): These systems contain plastic media with a high surface area that supports microbial growth, enhancing biological activity for nutrient removal.
