How Sodium Bisulfite (SBS) Is Used in Water Treatment: Practical Application Guide

Sodium Bisulfite (SBS) (亚硫酸氢钠) is one of the most widely specified disinfection, sterilization & bleaching used across municipal and industrial facilities. As a SBS antioxidant, it delivers reliable performance in the scenarios our customers ask about most: Mainly used as bleach, preservatives, antioxidants and bacterial inhibitors.

What Sodium Bisulfite (SBS) Is and How It Works

Sodium Bisulfite (SBS) is supplied as White crystalline powder. Its molecular formula is NaHSO3 (CAS 7631-90-5). Because of this physical form it dissolves and disperses predictably, which makes dosing and process control straightforward for plant operators.

Primary Applications

Its key application areas include: Mainly used as bleach, preservatives, antioxidants and bacterial inhibitors. In practice this means SBS antioxidant is selected for both routine maintenance and shock-treatment programs, depending on the water matrix and treatment goal.

• Process reliability: stable active content and consistent granule/tablet size improve dosing accuracy.
• Compatibility: works within existing dosing and storage setups common to disinfection, sterilization & bleaching programs.
• Logistics: available in 25KG PP/paper/PE bag, 500/1000/1200kg large bag, simplifying import and warehouse planning.

Why Buyers Choose This Grade

When specifying Sodium Bisulfite (SBS), buyers typically compare active content, packaging and the applicable standard (-). Selecting the right grade reduces consumption and protects downstream equipment.

Operators who also run complementary programs often pair this product with Chlorine Dioxide to cover the full treatment chain from clarification to disinfection.
