A Comprehensive Guide to Procurement, Synthesis, and High-Performance Applications
Aluminum Sulphate (formula: Al₂(SO₄)₃) is one of the most widely used chemical reagents across global manufacturing, municipal water infrastructure, and agricultural remediation projects. As a highly efficient coagulant, it acts by neutralizing colloidal charges, causing dissolved and suspended impurities to aggregate and precipitate out of aqueous solution. Shandong Pulisi Chemical Co., Ltd. supplies premium grade low-iron and non-iron Aluminum Sulphate to meet strict standards for water purification, paper sizing, and construction acceleration.
Aluminum Sulphate is synthesized through a controlled reaction between high-purity aluminum hydroxide or calcined bauxite and concentrated sulfuric acid. Depending on industrial requirements, Shandong Pulisi provides two primary grades designed for optimized efficiency and cost control:
| Specification Parameter | Non-Iron Grade (High Purity) | Low-Iron Grade (Standard Industrial) |
|---|---|---|
| Alumina ($Al_2O_3$) Content | ≥ 17.00% | ≥ 15.80% |
| Iron ($Fe$) Content | ≤ 0.005% | ≤ 0.50% |
| Water Insoluble Matter | ≤ 0.15% | ≤ 0.20% |
| pH Value (1% aqueous solution) | ≥ 3.0 | ≥ 3.0 |
| Physical Form | White crystalline powder, granules, or flakes | Light green or yellow flakes and granules |
When Aluminum Sulphate is dissolved in water, it hydrolyzes to form trivalent aluminum ions ($Al^{3+}$) and dynamic polymer hydroxyl complexes such as $[Al_8(OH)_{20}]^{4+}$ and $[Al_{13}(OH)_{32}]^{7+}$. These positively charged species exhibit a strong affinity for negatively charged colloidal particles (including silt, bacteria, and natural organic matter). Through a process of charge neutralization, adsorption, and sweep flocculation, the particles aggregate into heavy flocs that settle rapidly, clarifying the water column efficiently.
Why Global Enterprises Partner with Shandong Pulisi Chemical
Our strategic manufacturing location in Shandong's heavy industrial core ensures direct, pipeline-supported access to high-purity sulfuric acid and raw bauxite resources. This vertical integration buffers our partners from raw material market fluctuations, offering stable pricing pipelines.
We maintain highly secure and climate-controlled storage hubs at Qingdao Port, Tianjin Port, and major Western inland gateways (including Khorgos and Alashankou). This multi-modal logistical capability guarantees rapid maritime and overland rail shipment options to 100+ countries.
As a public company listed in 2023, Shandong Pulisi complies with strict regulatory transparency, comprehensive environmental control standards, and robust QC procedures audited by ISO 9001, German BV, and SGS. This guarantees secure financial and delivery compliance for major global tenders.
Note on Market Procurement: Industrial buyers often look for "cheap" pricing. While we offer highly competitive pricing lists due to massive scale economies and integrated production processes, we maintain strict quality thresholds that eliminate the risk of heavy-metal impurities commonly found in low-grade products from unregulated suppliers.
Optimizing Chemical Efficacy Across High-Demand Sectors
Utilized as a high-efficiency primary coagulant in municipal potable water production and wastewater systems. It successfully reduces Total Suspended Solids (TSS), biological oxygen demand (BOD), and dissolved phosphates to align effluent streams with modern regulatory discharge levels.
Acts as an essential sizing agent, facilitating rosin-alum sizing systems under acidic to neutral pH conditions. It secures rosin precipitates to wood fibers, optimizing paper printability, improving water resistance, and retaining pigments within the pulp suspension.
Engineered as an accelerator agent in industrial shotcrete and tunnel concrete blends. The sulfate ions catalyze early calcium aluminate crystallization phases, shortening setting times and increasing initial compressive strength for secure structural installations.
Applied to alkaline soils to lower structural soil pH by hydrolyzing and generating hydrogen ions ($H^+$). This improves crop absorption of essential micronutrients (like iron and phosphorus) and helps manage moisture in commercial farming operations.

B2B Procurement, Customization, Shipping & Quality Inquiries
Yes. We offer complete OEM services, including custom logo and label printing according to your specification documents. We provide multi-layer laminated woven bags, Kraft paper bags, and bulk ton bags configured with your branding and mandatory chemical handling codes.
Whether you are a mid-scale distributor or an industrial startup, we value your development. Our standard MOQ is designed for containerized safety, but we are open to negotiating smaller test trials or partial containers to help establish long-term partnership goals.
Our pricing is highly competitive as we optimize directly from our raw feedstock pipeline. Price structures are negotiable based on purchase volume, long-term supply agreements, and specific chemical grade requirements. Contact our representatives for a formal quotation matching the current market rate.
Yes. We provide free samples (typically 200g to 1kg) for client laboratory assays and pilot testing. Shipping costs can be discussed or arranged via your domestic express carrier account.
Absolutely. Backed by our warehousing facilities at Qingdao Port and Tianjin Port, and strategic rail corridors at Xinjiang border stations, we maintain stable shipping timelines. Our listed stock status ensures we carry healthy raw inventory safety margins to prevent delay risks.

The primary difference is the iron ($Fe$) impurity level. Non-Iron Aluminum Sulphate containing less than 0.005% Fe is white in color and critical for fine paper sizing, high-purity water clarification, and cosmetics manufacturing. Low-iron grades containing up to 0.5% Fe are yellowish/greenish and are commonly chosen for municipal raw water treatment, industrial effluent flocculation, and setting accelerators due to lower processing costs.
Aluminum Sulphate should be stored in dry, cool, well-ventilated warehouses away from alkaline chemicals, active metals, and moisture, as it is hygroscopic and exhibits a mildly acidic corrosive reaction when wet. We recommend using acid-resistant materials (such as plastics, FRP, or rubber-lined steel vessels) for storage containers and handling equipment.
