Typical Chemical Specifications
Active Alumina Content:
Typical Al2O3 concentration ranging from 15% to 17% depending on the industrial or water-treatment grade.
Iron Content (Fe2O3):
Strict thresholds maintained, ranging from ultra-low iron (<0.005%) for iron-free and non-ferric grades to standard industrial levels.
Water Insoluble Matter:
Minimized levels (<0.1%) to prevent clogging in automated dosing systems and storage tanks.
PH Value:
Controlled acidic baseline, typically ranging from 3.0 to 4.0 in a 1% aqueous solution to optimize coagulation kinetics.
Application Dosage and Operational Guidelines
Jar Testing Protocol:
Step-by-step recommendation for performing preliminary jar tests to determine the precise coagulant dosage required for varying raw water turbidity and organic loads.
Optimal pH Range:
Guidance on maintaining operational pH windows, typically between 6.5 and 7.5, to achieve maximum flocculation efficiency and residual aluminum control.
Co-Alumant Synergy:
Compatibility notes regarding the combined use of solid aluminum sulfate with polymeric flocculants (polyelectrolytes) to accelerate sedimentation velocity.
Core Water Treatment Applications
Drinking Water Treatment
Solid aluminum sulfate acts as an effective coagulant in potable water clarification, reducing turbidity and removing suspended colloidal particles. Procurement teams must verify that the selected grade satisfies local regulatory standards and drinking water certifications before purchase.
Industrial Wastewater Treatment
In wastewater management, aluminum sulfate promotes the destabilization of suspended solids and colloids, facilitating efficient flocculation, sedimentation, and filtration. Optimal dosage levels should be determined via jar testing or pilot plant evaluation.
Phosphorus Removal
Aluminum-based coagulants are widely utilized for chemical phosphorus precipitation in wastewater effluent streams. Performance depends heavily on influent chemistry, pH balance, alkalinity, and reactor configuration.
Safety and Environmental Compliance
Regulatory Standards:
Conforms to major international standards including NSF/ANSI Standard 60 for drinking water treatment additives where applicable.
Personal Protective Equipment (PPE):
Operational guidelines require chemical-resistant gloves, safety goggles, dust masks, and protective aprons during handling and dissolution to prevent skin and respiratory irritation.
Spill and Waste Management:
Containment protocols detail dry sweep procedures, avoidance of water runoff into natural water bodies, and neutralization guidelines for aqueous spills.
Because solid aluminum sulfate is moisture-sensitive, proper warehouse management directly impacts operational performance:
Storage Conditions: Store in a cool, dry, and well-ventilated covered warehouse. Keep bags elevated off the floor and away from direct moisture or humidity.
Caking Prevention: Avoid high stacking pressures that can induce caking in fine powder or flake formats during extended storage.
Dissolution Practice: When preparing stock solutions, use corrosion-resistant dissolution equipment (such as rubber-lined or plastic tanks) since aqueous aluminum sulfate solutions are weakly acidic.
Packaging, Logistics, and Quality Documentation
Solid aluminum sulfate is packed in moisture-resistant woven bags designed to protect product integrity during international transit.
Available Packaging: 25 kg bags, 50 kg bags, and heavy-duty ton bags.
Shipping Methods: Sea freight, rail, and multimodal transport options based on destination port requirements.
Quality Assurance Package: Every dispatch is supported by complete technical documents, including a Technical Data Sheet (TDS), Safety Data Sheet (SDS), and a batch-specific Certificate of Analysis (COA).
FAQ
Q: What is solid aluminum sulfate used for?
A: Solid aluminum sulfate is primarily utilized as an aluminum-based coagulant in water and wastewater treatment, alongside specialized industrial applications such as paper sizing and textile processing.
Q: What is the difference between flake and powder forms?
A: The main distinction lies in particle size and dissolution dynamics. Flake products feature larger particles suited for conventional dissolving tanks, whereas powder offers a high surface area for rapid dissolution.
Q: What particle size ranges are currently available?
A: Standard stock configurations include 0 to 3 mm for powder, 0 to 15 mm for granular, and up to 0 to 25 mm for flake variants. Exact distributions can be verified for specific orders.
Q: What is the standard minimum order quantity (MOQ)?
A: The standard listed MOQ for bulk solid aluminum sulfate specifications is 25 MT.
Q: What documents are provided with each shipment?
A: Shipments include a Technical Data Sheet (TDS), Safety Data Sheet (SDS), and a batch-specific Certificate of Analysis (COA). Additional compliance certificates can be arranged depending on destination market requirements.
