Import 30%Yellow Poly Aluminium Chloride — Buy in wholesale FOB from Supplier in Hong Kong

30%Yellow Poly Aluminium Chloride from Henan Xinhuan Water Treatment Material Co., Ltd. is a coagulant-grade PAC with an aluminium oxide content of approximately 30%, supplied from Hong Kong. This inorganic polymeric compound functions through charge neutralisation and bridging mechanisms to aggregate suspended solids, colloidal matter, and dissolved organic contaminants in raw water matrices. The 30% designation refers to the Al₂O₃ equivalence by weight, placing this grade in the mid-to-high basicity category suitable for both potable and industrial water treatment circuits. Its yellow colouration indicates the presence of iron traces or lower-purity synthesis feedstock, distinguishing it from the white pharmaceutical-grade variant.

The material is manufactured via acid dissolution of aluminium-containing precursors followed by partial neutralisation and polymerisation, yielding a product with typical basicity between 40% and 70% (standard range for this colour class). Particle sizing is typically granular or fine powder, with dissolution rates optimised for turbid water conditions where rapid floc formation is critical. The 30% Al₂O₃ content offers a practical balance between chemical activity and handling safety, providing adequate coagulant dose without the hygroscopicity and dust hazards associated with higher-concentration powders. pH adjustment downstream is usually minimal compared with traditional alum or ferric salts, reducing lime or caustic consumption at the treatment plant.

Primary applications include municipal drinking water clarification, pulp-and-paper effluent treatment, textile dyehouse wastewater, and oil-field produced water conditioning. Buyers are typically municipal water authorities, industrial effluent treatment operators, and bulk chemical distributors serving Southeast Asian and African markets. The supplier is based in Zhengzhou, Henan Province, with the listing indicating a Hong Kong trade presence or registration. Importers should confirm the exact basicity range, bulk density, and insoluble residue percentage before finalising technical specifications, as these parameters affect dosing calculations and sludge volume projections.

Henan Xinhuan Water Treatment Material Co., Ltd. is headquartered at No.76, Science Avenue, Zhongyuan District, Zhengzhou, Henan Province, with this listing registered under a Hong Kong origin designation that likely reflects a trading subsidiary, export licence, or regional distribution arrangement. The company holds a Harbor trust tier on the platform, with a response rate of 0.00% and no recorded average response hours, indicating that direct communication channels may be unmonitored or that the supplier relies on alternative contact methods. The address structure places it in a central Chinese industrial zone with established chemical manufacturing infrastructure, though no specific plant accreditations, ISO certifications, or production capacity figures are provided in the source data.

The listing presents only the product description and basic supplier registration details; it does not disclose years in operation, annual output, export licence numbers, or client references. Buyers should verify company registration documents, hazardous chemical handling permits, and any drinking-water-grade approvals (such as NSF/ANSI 60 or equivalent Chinese GB standards) directly with the supplier before committing to volume orders. The absence of response metrics suggests that email or platform messaging may not yield rapid replies; telephone or WeChat contact during Chinese business hours is likely more effective for technical discussions and sample requests.
