3 Innovation 3
4 Fundamentals of Nutrient Removal 4
5 Nutrient Removal Basics Nitrogen Removal Nitrification requires oxygen = energy for blowers/aerators Denitrification requires carbon = organics needed; organics that could have been used for energy production Phosphorus Removal Phosphorus Accumulating Organisms (PAO) require soluble carbon = competition with denitrification for organics; organics could have been used for energy production 5
6 Required and Available Energy for Wastewater Treatment, Exclusive of Heat Energy Energy required for secondary wastewater treatment 1,200 to 2,400 MJ/1000 m3 Energy available in wastewater for treatment 5,850 MJ/1000 m3 COD = 500 mg/l) Energy available in wastewater is 2 to 4 times the amount required for treatment 6
7 Organic Carbon vs. Energy 1.3 MJ/person per day ($0.01/person/day) Can be readily recovered as energy Can also be recovered as value added carbon ($0.05-$0.5/person/day) methane generated from anaerobic digestion bioplastics (i.e., PHA) via activated sludge alginate/biogels via granular sludge soluble organics via fermentation 7

9 Nitrogen Removal Processes 9
10 Carbon Requirements for Mainstream Biological Nitrogen Removal Processes Constituent Carbon required for nitrogen removal (mg COD /mg N) Net Process Oxygen Requirement (mg O2/mg N Converted to N2) Nitrification denitrification Nitritationdenitritation Partial nitritationdeammonification Influent COD:N Ratio often mgcod/ mgn Opportunities available to divert COD out of the plant and use it for energy generation The conundrum of aerobic treatment is that electrical energy is needed to destroy chemical energy (COD) Process units available to redirect Carbon for energy generation 10
11 Conventional Nitrogen Removal Processes TN 8-10 mg/l TN 3-5 mg/l Electricity ( e.g., aeration, pumping) Infrastructure (facility footprint) Chemicals (e.g., external carbon, alkalinity, polymers) 11
12 Conventional Nitrification-Denitrification Autotrophic Bacteria Aerobic Environment Heterotrophic Bacteria Anoxic Environment 75% O 2 (energy) ~100% Alkalinity 25% O 2 (energy) 1 mole Ammonia (NH 3 / NH 4 + ) 1 mole Nitrite (NO 2- ) Ammonia Oxidizing Bacteria (AOB) 1 mole Nitrate (NO 3- ) Nitrite Oxidizing. Bacteria (NOB) 40% Carbon (BOD) 1 mole Nitrite (NO 2- ) 60% Carbon (BOD) ½ mol Nitrogen Gas (N 2 ) 12
13 Advances in Nitrogen Removal 13
14 Recent Advances in N Removal started with Sidestream Treatment 14
15 Anammox Bacteria Very Slow Growth 10 day doubling time at 20 C SRT (30-50 days) Sensitive to: Nitrite causes irreversible loss of activity toxicity based on concentration & exposure time NH 4 + : NO 2 - ratio 1 : 1.3 DO - reversible inhibition Free ammonia (<10 mg/l) Temperature >30 C preferred ph (neutral range) Bernhard Wett, Gallon 80 Gallons 635 Gallons 132,000 Gallons
16 Coupled Aerobic-Anoxic Nitrous Decomposition Operation (CANDO) Couples nitritation (NH3 conversion to NO2) followed be incomplete denitrification (NO2 conversion to N2O) N2O is captured and can be used for combustion (e.g., biogas engine or boiler) Increase power output making the net energy recovery much more favorable Gao, Scherson and Wells

18 From Green House Gas to Green Biofuel CARBON RECOVERY? CH 4 CH 3 OH NH 3 AOB NH 2 OH ANAEROBIC DIGESTION NO 2 - BNR Process NITRIFICATION NO 3 - Su et. al., 2015
19 Wastewater C:N Ratio C:N ratio into the bioreactor may be a key control factor in defining predominant pathway for TN removal Control denitrification by heterotrophic organisms Higher C:N ratio 6-10 :1 range? Heterotrophs Outcompete Medium C:N 3-5 :1 range? Lower C:N ratio 1-3 :1 range? Anammox Outcompete Conventional Nitrification / Denitrification Nitrite Shunt Deammonification If C/N ratio is sufficient for conventional nitrification/denitrification, opportunity to: Reduce C:N ratio by CEPT and HRAS and reduce Energy needed for nitrogen removed Divert carbon to anaerobic digestion to both recover energy (CHP system) 19
