How Aluminium Sulphate (Non-Fe) Is Used in Water Treatment: Practical Application Guide

Aluminium Sulphate (Non-Fe) (无铁硫酸铝) is one of the most widely specified industrial water plant treatment chemicals used across municipal and industrial facilities. As a non-ferric alum, it delivers reliable performance in the scenarios our customers ask about most: Water treatment agent for drinking water; sizing agent for paper industry; raw material for alkali-free accelerator; flame retardant and soil improvement.

What Aluminium Sulphate (Non-Fe) Is and How It Works

Aluminium Sulphate (Non-Fe) is supplied as White solid, block, flake, granule or powder. Its molecular formula is Al2(SO4)3 (CAS 10043-01-3). 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: Water treatment agent for drinking water; sizing agent for paper industry; raw material for alkali-free accelerator; flame retardant and soil improvement. In practice this means non-ferric alum 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 industrial water plant treatment chemicals programs.
• Logistics: available in 25/50/1000kg inner plastic outer woven bag, simplifying import and warehouse planning.

Why Buyers Choose This Grade

When specifying Aluminium Sulphate (Non-Fe), buyers typically compare active content, packaging and the applicable standard (HG/T2225-2018). Selecting the right grade reduces consumption and protects downstream equipment.

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