In industries where precision, consistency, and chemical reliability define success, sodium bisulphate stands out as a versatile and indispensable compound. At ATDM, we don’t just supply chemicals we deliver performance, backed by export expertise, rigorous quality control, and deep industry understanding.
Whether you are in water treatment, petrochemicals, textiles, or industrial cleaning, our sodium bisulphate is engineered to meet demanding operational standards across global markets.
Sodium bisulphate (NaHSO₄) is an acidic salt formed from the partial neutralization of sulfuric acid with sodium hydroxide or sodium chloride. It appears as a dry, granular or crystalline substance and is highly soluble in water.
Sodium bisulfate other name / common name:
Sodium hydrogen sulfate
Sodium acid sulfate
Dry acid (widely used in pool maintenance industries)
Despite the naming variations, all refer to the same functional compound widely used for pH control and industrial processing.
At ATDM, we approach chemical supply as a partnership, not just a transaction.
What sets us apart:
Consistent Purity Levels – Strict QC ensures uniform composition across batches
Export-Ready Packaging – Designed for long-distance logistics and safe handling
Bulk Availability – Including Sodium Bisulfate 25kg bags and custom packaging
Reliable Documentation – Full compliance with international shipping and safety standards
Application Support – Guidance tailored to your industry use case
We understand that in industrial environments, even minor inconsistencies can lead to major disruptions. That’s why reliability is built into every shipment.
Understanding product behavior is critical for industrial integration.

One of the biggest strengths of sodium bisulphate is its versatility. It plays a crucial role across multiple sectors:
1. Water Treatment & pH Adjustment
Sodium bisulfate is widely used to lower pH levels in water systems. Compared to liquid acids, it offers:
Safer handling
Easier storage
Precise dosing
Applications include:
Swimming pools
Industrial cooling systems
Wastewater treatment plants
2. Petrochemical Industry
In petrochemical processing, sodium bisulphate serves as:
A neutralizing agent
A cleaning compound for equipment
A component in chemical synthesis
Its controlled acidity makes it ideal for sensitive reactions where stronger acids may be too aggressive.
3. Industrial Cleaning & Descaling
Sodium bisulphate is highly effective in removing:
Rust
Limescale
Mineral deposits
It is commonly used in:
Boiler cleaning
Metal surface preparation
Equipment maintenance
4. Textile Industry
In textile processing, sodium bisulfate is used for:
pH control during dyeing
Neutralizing alkaline residues
Enhancing color consistency
5. Food Industry (Controlled Use)
In food-grade applications (where approved), sodium bisulphate acts as:
Acidifying agent
Preservative component
(Note: Industrial-grade product from ATDM is typically not intended for direct food use unless specifically certified.)
6. Leather Processing
Used for:
pH adjustment during tanning
Removing excess alkalinity
Sodium Bisulphate vs Sodium Bisulfite Formula
It’s important not to confuse sodium bisulfate (NaHSO₄) with sodium bisulfite (NaHSO₃).
Key Differences:
| Property | Sodium Bisulphate | Sodium Bisulfite |
|---|---|---|
| Formula | NaHSO₄ | NaHSO₃ |
| Nature | Acidic salt | Reducing agent |
| Main Use | pH reduction | Preservative, antioxidant |
| Industry Use | Water treatment, cleaning | Food, pulp & paper |
This distinction is critical when selecting the right chemical for your process.
