Oxidant removal
Specified to reduce free residual chlorine and other oxidants before sensitive equipment or chemical steps.
Product Water Treatment
Sodium Bisulfite (Dechlorination)
Reducing agent supplied to specification for dechlorination (residual oxidant removal) and dissolved oxygen reduction support in water systems—often specified to protect downstream equipment and processes.
✓ NaHSO3
✓ Dechlorination
✓ Reducing agent
✓ Drum / IBC / bulk
✓ SDS/COA/TDS on request
Packaging: drums / IBC / bulk (as applicable)
Documentation: SDS / COA / TDS on request
Lead time depends on lane, seasonality & volume
For accurate dosing support and quotation alignment, include your oxidant type (free chlorine / chloramine), target residual after treatment, flow rate, and the point of injection.
Applications
Sodium bisulfite is commonly applied where residual oxidants must be removed before sensitive downstream steps. It can also support dissolved oxygen reduction programs where a reducing agent is specified.
- Dechlorination prior to membrane/RO and other oxidation-sensitive processes
- Residual oxidant quenching in utility and industrial water systems
- Dissolved oxygen reduction support in selected programs (process-dependent)
Program control
Supports measurable control points (residual oxidant after injection) under your operating procedures.
Procurement repeatability
Strength, impurities, and packaging can be standardized for repeat ordering and receiving QA checks.
Exact dosing and suitability depend on water chemistry and oxidant type (free chlorine vs. chloramine) and must be validated by your program and testing.
Why dechlorination programs specify sodium bisulfite
In many systems, the procurement goal is reliable residual oxidant removal with predictable logistics. Controls focus on product strength, compatibility with dosing equipment, and documentation readiness.
Fast oxidant quench
Used to reduce residual oxidants to meet downstream process protection or discharge requirements (program dependent).
Liquid handling
Typically supplied as a solution suitable for metered dosing and bulk handling under appropriate materials compatibility.
Spec-driven buying
Concentration and impurity limits can be defined for repeat procurement and QA acceptance.
Documentation pack
SDS/COA/TDS can be aligned to receiving procedures and audits.
Specification & grade selection framework
For sodium bisulfite, selection usually comes down to required active strength, any impurity limits (application-dependent), and packaging/handling requirements.
Active concentration
Define the desired concentration and acceptance criteria on COA (where applicable).
Impurities
Specify limits if needed for sensitive equipment or compliance requirements.
Stability & logistics
Share storage conditions, consumption rate, and preferred packaging for best-fit lane selection.
If you currently use sodium metabisulfite (SMBS) and dissolve on-site, tell us—some programs prefer bisulfite solution to simplify handling.
Typical specifications & formats
Values depend on grade and customer requirements. Confirm final values on quotation (SDS/TDS/COA as applicable).

Indicative COA/TDS fields (example)
Typical procurement fields for sodium bisulfite solution can include (lane-dependent):
| Property | Typical description | Why it matters |
|---|---|---|
| Assay / active content | Reported per spec | Primary control for dosing and dechlorination performance. |
| Density / specific gravity | Reported (as applicable) | Used for volume-to-mass conversions and receiving checks. |
| pH | Reported range (as applicable) | Compatibility and handling indicator for system design and QA. |
| Sulfite/sulfate profile (by spec) | Optional reporting | May matter for certain discharge limits or downstream chemistry. |
| Metals / impurities | Optional limits | Important for sensitive equipment or strict specifications. |
| Appearance | Clear to pale yellow | Basic receiving and identity check. |
Specifications may vary depending on batch, origin, and packaging selection. For critical applications, request documentation in advance and validate under your site procedures.
Handling & storage guidance
Sodium bisulfite is a reducing agent. Safe handling depends on concentration, ventilation, and compatibility with your equipment. Always follow the supplied SDS and your site EHS procedures.
PPE (typical)
Eye/face protection and chemical-resistant gloves; additional PPE as required by your risk assessment and transfer method.
Storage
Store in suitable containers, keep closed, and follow temperature/ventilation guidance in the SDS.
Compatibility
Use compatible pumps/hoses/tanks for bisulfite service; avoid unintended mixing with oxidizers.
For dechlorination applications, share your injection point materials (pipes, seals, pumps) and any restrictions so the correct lane and packaging can be proposed.
Supply & procurement details
Structured for repeat buying: specification alignment, documentation readiness, and practical packaging lanes.
Packaging lanes
Drums, IBC, and bulk options depending on destination, volume, and handling constraints.
Documentation set
SDS/TDS on request. COA availability and fields depend on lane and order structure.
Lead time
Depends on origin lane, packaging, route constraints, and order size. Confirmed on quotation.
FAQ
Common technical and procurement questions for sodium bisulfite (dechlorination).
Is sodium bisulfite the same as sodium metabisulfite?
They are related reducing agents used in similar programs. Some sites prefer bisulfite solution to simplify handling; others use metabisulfite solids and dissolve on-site. Tell us your current setup and we’ll align the appropriate option.
What information helps you quote accurately?
Oxidant type, target residual, flow rate, injection point, product concentration requirement, packaging, destination, and documentation needs.
Do you provide SDS/COA/TDS?
Yes—documentation is available on request and depends on grade and supply lane.
Which packaging is typical?
Drums and IBC are common; bulk may be available depending on destination and volume. Confirm on quotation.
Any important compatibility notes?
Segregate from oxidizers unless your program explicitly controls the reaction. Always follow SDS and your site EHS procedures.
Can you match impurity limits?
Often yes—if you specify required limits and COA fields in your inquiry, we’ll route to the best lane.
