Why It Matters
Collection systems, lift stations and headworks dose nitrate, iron salts or oxidants in bulk to suppress hydrogen sulfide that drives odor complaints and concrete corrosion. Demand is recurring and tied to municipal odor-abatement and asset-protection programs
Solution Approach
Collection systems, lift stations and headworks dose nitrate, iron salts or oxidants in bulk to suppress hydrogen sulfide that drives odor complaints and concrete corrosion. Demand is recurring and tied to municipal odor-abatement and asset-protection programs RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (6)
Calcium Nitrate
CAS 13477-34-4
Acids & Salts
pH Adjustment
In catalog. Supplies nitrate as a preferred electron acceptor so bacteria respire on nitrate instead of generating sulfide; prevents H2S formation rather than treating it afterward
Physical Description: Colorless hygroscopic crystals
Full Details
Ferric Chloride
CAS 7705-08-0
Acids & Salts
High-performance coagulant
1773 (FERRIC CHLORIDE) · Class In catalog. Ferric iron precipitates dissolved sulfide as insoluble iron sulfide, removing it from the liquid and vapor phase
Melting Point: 306 °C Boiling Point: 315 °C at 760 mmHg (Decomposes) Density: 2.8 at 20 °C (anhydrous solid)
Full Details
Ferrous Sulfate
CAS 7720-78-7
Acids & Salts
pH Adjustment
In catalog. Iron(II) reacts with sulfide to form FeS precipitate; a lower-cost iron source for sulfide binding
Physical Description: Ferrous sulfate appears as a greenish or yellow… Appearance: White orthorhombic crystals, hygroscopic Boiling Point: > 300 °C
Full Details
Magnesium Hydroxide
CAS 1309-42-8
Specialty Additives
pH Adjustment
In catalog. Raises and buffers pH, shifting the sulfide equilibrium toward non-volatile bisulfide ion and suppressing H2S off-gassing without overshoot
Physical Description: White odorless solid; Colorless or white solid;… Appearance: White, hexagonal crystals Odor: Odorless
Full Details
Hydrogen Peroxide (Leaching / Process Oxidant)
CAS 7722-84-1
Polymers & Resins
Peroxide-based oxidizer
2015 (HYDROGEN PEROXIDE, AQUEOUS SOLUTION, STABILIZED, WITH MORE THAN 60% HYDROGEN PEROXIDE) · Class Oxidizes dissolved sulfide to sulfate or elemental sulfur for fast odor knockdown at problem points
Melting Point: 0 °C Boiling Point: 150 °C at 760 mmHg Density: 1.11 at 20 °C
Full Details
