Grant

• Expand the applicability of densification strategies to plants of varied size and process configurations without anaerobic selectors, with a goal of stable performance across diverse plant designs, by:
  • Refining design parameters to optimize biological selection, such as food-to-microorganism (F/M) ratios, carbon to nitrogen ratios (C/N), selector sizing, hydraulic retention times (HRT), solids retention times (SRT), selective wasting schedules, and aeration and mixing
  • Investigating the impact of floc size, granule-to-floc ratio, and dissolved oxygen (DO) control on simultaneous nitrification-denitrification (SND) in densified systems.
• Bridge research findings with practical implementation by developing a “recipe book” for densification, ensuring findings translate into actionable strategies for wastewater utilities.
