Aluminum Sulfate Product Grades and Forms
Different wastewater treatment processes require distinct product forms and handling characteristics. Our aluminum sulfate range is organized by physical form to match your facility's dissolution and automated dosing systems.
Aluminum Sulfate Powder: Fine-particle structure engineered for rapid dissolution and preparation of treatment solutions. Ideal for systems requiring fast wetting and immediate coagulation response.
Aluminum Sulfate Flake: Solid flake material designed for bulk storage, heavy-duty transportation, and subsequent dissolution prior to feeding. Standard flake sizing ranges up to approximately 0 to 25 mm.
Aluminum Sulfate Granular: Controlled solid granular form optimized for specialized mechanical feeding and continuous dissolution setups, with typical sizing around 0 to 15 mm.
Water Treatment Grade: Formulated specifically for coagulation and clarification processes where consistent active aluminum content and controlled impurity profiles are critical.
Iron-Free Grade: Selected when sensitive industrial wastewater streams or downstream processes require minimal iron contribution from the coagulant.

Aluminum sulfate, commonly referred to as alum, functions as an aluminum-based inorganic coagulant. Upon introduction to wastewater, aluminum species formed via hydrolysis neutralize the surface charges of suspended and colloidal particles. This destabilization promotes the agglomeration of smaller particles into larger flocs, which are subsequently removed through sedimentation, clarification, or filtration.
Aluminum sulfate is also widely deployed for chemical phosphorus removal. Aluminum ions react with soluble orthophosphate to form solid precipitates, which are then cleared through downstream solids separation stages.
Effective deployment depends strictly on wastewater chemistry, including pH, alkalinity, mixing dynamics, and competing ions.
Typical Wastewater Treatment Applications
Suspended Solids Removal:
Acts as a primary coagulant to destabilize colloids, enhancing clarity prior to filtration.
01
Phosphorus Removal:
Facilitates chemical phosphorus precipitation to meet strict municipal discharge limits. Dosages are optimized via jar testing.
02
Industrial Wastewater Clarification:
Treats complex effluent streams across textile and dyeing, paper and pulp, and general chemical processing plants.
03
Color Reduction:
Destabilizes color-causing organic and colloidal compounds during the coagulation phase.
04
ludge Separation:
SDeployed alongside polymer flocculants, such as polyacrylamide, to improve overall floc structure and settling rates.

How to Select the Right Aluminum Sulfate
Define the Treatment Objective: Identify whether the primary goal is suspended solids reduction, phosphorus removal, color abatement, or general clarification.
Select the Physical Form: Match powder, flake, or granular options to your facility's storage silos, dissolving tanks, and feeding pumps.
Analyze Wastewater Characteristics: Review incoming pH, alkalinity, turbidity, temperature, and organic loading.
Finalize Chemical Specifications: Lock in parameters such as minimum active Al2O3, iron limits, and maximum insolubles.
Storage, Handling and Shelf Life
Solid aluminum sulfate products require proper warehouse management to maintain physical integrity:
Moisture Protection:
Solid forms are hygroscopic. Products should be stored in dry, well-ventilated indoor warehouses on pallets away from direct contact with concrete floors.
Packaging Integrity:
Standard deliveries use moisture-barrier lined bags, including 25 kg, 50 kg, or jumbo bags, to prevent caking.
Dissolution Handling:
Personnel handling solid dissolving operations should follow standard industrial safety protocols, utilizing appropriate personal protective equipment for dust and chemical handling.
Consistent coagulant performance relies on tightly monitored production parameters. Our manufacturing workflow follows a structured sequence:
Raw material preparation followed by reactor reaction, crystallization or drying, particle processing, automatic packaging, and final warehouse storage.
Rigorous testing protocols check active Al2O3 levels, iron content, insoluble residues, particle size distribution, and batch-to-batch consistency prior to release.
