How Polyferric Sulphate (Solid) SPFS Is Used in Water Treatment: Practical Application Guide

Polyferric Sulphate (Solid) SPFS (聚合硫酸铁(固体)) is one of the most widely specified industrial water plant treatment chemicals used across municipal and industrial facilities. As a PFS coagulant, it delivers reliable performance in the scenarios our customers ask about most: High quality polymer flocculant for industrial wastewater (printing & dyeing), also casting, paper making, medicine, leather.

What Polyferric Sulphate (Solid) SPFS Is and How It Works

Polyferric Sulphate (Solid) SPFS is supplied as Yellow or bronzing powder or granules. Its molecular formula is [Fe2(OH)n(SO4)3-n/2]m (CAS 1327-41-9). 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: High quality polymer flocculant for industrial wastewater (printing & dyeing), also casting, paper making, medicine, leather. In practice this means PFS coagulant 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 25/50kg bags, simplifying import and warehouse planning.

Why Buyers Choose This Grade

When specifying Polyferric Sulphate (Solid) SPFS, buyers typically compare active content, packaging and the applicable standard (GB14591-2006(II)). Selecting the right grade reduces consumption and protects downstream equipment.

Operators who also run complementary programs often pair this product with Aluminium Sulphate (Non-Fe) to cover the full treatment chain from clarification to disinfection.
