Q
What is Polyferric Sulfate (PFS) and what is its CAS number?
Polyferric Sulfate (PFS) is an inorganic flocculant used primarily for water treatment applications. Its CAS number is 10028-22-5. It appears as a brown solid and is available in 25 kg bags for industrial use.
Q
What industries can use Polyferric Sulfate?
PFS is widely applicable across multiple industries including drinking water purification, urban water supply, papermaking, textiles, chemical manufacturing, industrial effluent treatment, and municipal sewage systems.
Q
What is the minimum all-ferric content required for Polyferric Sulfate?
Both first-rate and qualified grades of PFS require a minimum all-ferric content of 19.5%. The reducing substance content (calculated as Fe²⁺) must not exceed 0.15% for both grades.
Q
What is the pH range of a Polyferric Sulfate water solution?
A 10 g/L water solution of PFS has a pH range of 1.5 to 3.0. Despite its acidic solution pH, PFS is effective across a wide range of source water pH levels and temperatures.
Q
Is Polyferric Sulfate environmentally friendly?
Yes. PFS is formulated to align with stringent environmental regulatory standards. Its low dosage requirements minimize chemical consumption, and its efficient flocculation process reduces contaminant levels with minimal ecological impact, supporting sustainable water management.
Q
Can Polyferric Sulfate be customized to meet special quality requirements?
Yes. Custom production is available for clients with special quality requirements. Products can be manufactured according to client-specified indicators, ensuring the product meets the precise technical needs of your application.
