About Hydrogen Sulfide (HAbout Hydrogen Sulfide (H22S)S)About Hydrogen Sulfide (HAbout Hydrogen Sulfide (H22S)S)
H2SMost Common Sulfide in Wastewater: H2S
– Gaseous phase molecule– Soluble in water- carried by wastewater flow– Odorous- rotten eggs– Highly corrosive- precursor to H2SO4 (sulfuric acid) Highly corrosive precursor to H2SO4 (sulfuric acid)

• Anaerobic layers thrive with – low DO– low pH– warmer temperatures
Anaerobic (SRB): Desulfovibrio desulfericans bacteria
Sulfide CycleSulfide CycleSulfide CycleSulfide Cycle• Sulfate (SO4) commonly found in water where:
SO4 + organic matter S= + H2O + CO2 S= + 2H+ HH22SS• Sulfides are produced through anaerobic respiration:

Vapor Phase: Vapor Phase: Extraction ConsiderationsExtraction ConsiderationsVapor Phase: Vapor Phase: Extraction ConsiderationsExtraction Considerations
• Costs – Equipment Capital Costs
• Moderate to high procurement costsModerate to high procurement costs– Site Costs
• Engineering, permits & constructionR i t– Recurring costs
• Electrical, water, media, filters, maintenance
• Limitations– H2S peak concentrations can overwhelm
treatment– Capital & operating costs– Sites must accommodate large footprint
No H S source treatment– No H2S source treatment– No corrosion treatment

Vapor Phase: Vapor Phase: Infusion MethodsInfusion MethodsVapor Phase: Vapor Phase: Infusion MethodsInfusion Methods
• Ozone mist reaction– Treatment is an ozone, air and
water “mist”water “mist”– Highly effective oxidizer
• LimitationsLimitations – No H2S source treatment
• Treats head space not flowO i t– No corrosion control
• H2S dissolved in flow creates downstream
Ozone-air-water vapor form a mist in the head space
creates downstream corrosion potential
– Dosing control limitedg• Too much can damage
infrastructure
Liquid Phase: Liquid Phase: Biological MethodsBiological MethodsLiquid Phase: Liquid Phase: Biological MethodsBiological Methods• Two types of biological
treatmentsNew bacteria added– New bacteria added
– Bio-chemical additives to enhance resident “good” biology
• Advantages– Perceived as “green” versus chemicals– Fewer side effects than chemicals– Fewer side effects than chemicals
• Limitations– Treatment takes weeks/months to take
effect– Tests are prolonged & expensive– Sensitive to chemical changes inSensitive to chemical changes in
collections system– High cost compared to chemicals
Liquid Phase: Liquid Phase: Chemical TreatmentsChemical TreatmentsLiquid Phase: Liquid Phase: Chemical TreatmentsChemical Treatments• Sulfide scavengers- Ferric (Iron) Salts
– Ferric Chloride FeCl3 / Ferrous Chloride FeCl2Advantages• Advantages– Low cost per gallon $0.70 to $1.00/ gallon– Proven effective for H2S odor2
Limitations Highly corrosive to pipes and equipment
2FeCl3 + 3H2S ↔ Fe2S3(s) + 6HCl Fe2S3(s) forms precipitants & sediments Aggressively removes dissolved oxygen from the water
Ferric chloride treated line with signature black color- Oxygen depleted
gg y yg4Fe2+ + 3O2 ↔ Fe2O3(s) (rust)
Low DO and pH increases H2S production & release Does not treat non-sulfide odors i e VOC ammonia Does not treat non-sulfide odors i.e., VOC, ammonia
Liquid Phase: Liquid Phase: Chemical TreatmentsChemical TreatmentsLiquid Phase: Liquid Phase: Chemical TreatmentsChemical Treatments• Sulfide oxidizer- hydrogen peroxide
H2O2Powerful & effective oxidizer
H d
– Powerful & effective oxidizerH2O2 + H2S → 2H2O + S0 (Neutral to Acidic)
• AdvantagesHydrogen Peroxide
g– Oxidizes sulfides and…– Increases dissolved oxygen (DO)
Limitations• Limitations– Cost at $3.50 (35%) to $5.00 (50%) per
gallon (national average)– Worker must be protected – Needs special site containment– Requires site storage and regular q g g
deliveries
Liquid Phase: Liquid Phase: Chemical TreatmentsChemical TreatmentsLiquid Phase: Liquid Phase: Chemical TreatmentsChemical Treatments• pH control: Magnesium Hydroxide
Mg(OH)2– Magnesium hydroxide: g y
• “Milk of Magnesia”, “Thioguard” – Mechanism:
• pH of 9 “holds” H2S in solutionp 2
– ~$2.50 / gallon (national average)
• AdvantagesRelatively safe to handle– Relatively safe to handle
• Limitations– Does not react with H2S– Tanks must be mixed or even heated to avoid
hardening– Users report increased issues with pump
cloggingclogging– No effect on ammonias or VOCs

– Calcium nitrate Ca(NO3)2, saltpeter, “Bioxide” (Siemens)– ~$2.00 / gallon (national average)
• Advantages• Advantages– Safe for handling & low toxicity– Slower reaction helps with downstream treatment
“Bioxide” widely used & considered low risk decision– “Bioxide” widely used & considered low risk decision
• Limitations– Feeds the anaerobic layer & may require higher usage over
time– Increases nitrate levels that may impact WWTP– Increases grease mat formation rates in wet wells
