Import Best Selling Polyferric Sulfate(Pfs) — Buy in wholesale FOB from Supplier in Hong Kong

Polyferric sulfate (PFS) is an iron-based inorganic polymer coagulant used extensively in wastewater treatment and drinking water purification. The solid form presents as a light yellow powder with strong hygroscopic properties, dissolving readily in water to produce a reddish-brown transparent solution. Henan Xinhuan Water Treatment Material Co., Ltd. supplies this material with extremely high flocculation capacity and rapid sedimentation characteristics, making it suitable for a broad spectrum of industrial and municipal applications where suspended solids removal is critical.

The powder form of PFS typically contains ferric iron in polymeric complexes that bridge and neutralise colloidal particles more efficiently than conventional iron salts. Standard grades for water treatment applications typically assay 21-22% as Fe3+ with a basicity range of 8.0-16.0%, though buyers should request the specific certificate of analysis for this batch. The material's hygroscopic nature demands sealed packaging with moisture barriers; standard industry packaging uses double-layer polyethylene liners within woven polypropylene bags. Storage in dry, ventilated conditions away from alkaline substances prevents caking and preserves reactivity.

Municipal water works, industrial effluent plants, and paper mills represent the primary procurement segments for PFS from Henan Xinhuan. The coagulant performs across pH ranges of 4-11, though optimal dosing typically falls between 6.5-8.5 depending on target contaminant profiles. Buyers should confirm minimum order quantities, available Incoterms, and lead times directly with the supplier, as these transaction terms are not stated in the available listing data. Sample testing against specific water matrices is advisable before bulk commitment, given variability in raw water composition and treatment objectives.

Henan Xinhuan Water Treatment Material Co., Ltd. maintains its registered address at No.76, Science Avenue, Zhongyuan District, Zhengzhou, within Henan province, with the listing origin indicated as Hong Kong. The supplier holds a harbor trust tier classification, which represents a baseline verification level within the platform's trust framework. Notably, the response rate displays as 0.00% with zero average response hours recorded, indicating no response history is currently available for this supplier profile. Buyers should factor this communication uncertainty into their sourcing timeline and consider proactive follow-up methods.

The listing provides no stated information regarding production capacity, warehouse locations beyond the Zhengzhou address, specific quality management certifications, or established client references. What the source description does confirm is the supplier's focus on polyferric sulfate as a core water treatment chemical, with explicit emphasis on its hygroscopic properties, flocculation performance, and application breadth. Prospective buyers should request documentation covering ISO certification status, material safety data sheets, and batch consistency records before placing orders. The absence of response metrics suggests direct engagement through multiple channels may prove necessary to establish reliable communication.
