Product Water Treatment
Aluminum Sulfate (Alum)
A classic inorganic coagulant used to reduce turbidity and color, destabilize colloids, and improve clarification in water and wastewater treatment. Also used in paper processes and various industrial clarification steps where reliable, economical coagulation performance is required.
Formats: solid (lumps/granular/powder) or liquid solution (grade dependent)
Documentation: SDS / COA / TDS on request
Packaging: bags / drums / IBC / bulk (as applicable)
Why Alum is frequently selected
Alum is widely used because it provides dependable coagulation at practical cost-in-use, with broad availability and proven performance for turbidity/color reduction and general clarification. It is often evaluated alongside PAC and ferric salts depending on raw-water characteristics, sludge strategy, and plant constraints.
- Proven, widely adopted coagulant for municipal and industrial treatment
- Effective for many turbidity and color reduction scenarios (jar tests confirm)
- Solid or liquid formats to match your storage and dosing setup

Typical buying scenarios
Alum is commonly purchased for clarification and treatment systems where turbidity/color reduction and stable operation are required. Share your water source, treatment step, and constraints so we can propose an appropriate grade and supply format.
- Municipal or industrial water treatment (clarification and filtration support)
- Wastewater and effluent treatment (solids removal and clarification)
- Paper/process operations where alum is used for process control (system dependent)
Availability, lead time, and the best supply format depend on your grade selection, packaging, and destination lane. We quote against your exact requirements.
Applications
Aluminum Sulfate is used to destabilize colloids and promote floc formation, enabling separation of suspended solids and improved clarification. It is applied in water treatment, wastewater treatment, and certain process industries where clarification and solids removal are required.
- Coagulation and clarification (turbidity/color reduction)
- Pretreatment ahead of filtration (process dependent)
- Wastewater and industrial effluent treatment (solids removal support)
- Paper process applications (process control use cases, system dependent)
- Clarification steps in compatible industrial processes
Key performance drivers
Alum performance depends on raw-water chemistry, alkalinity, pH, temperature, mixing/flocculation conditions, and solids load. Plants typically confirm dose and operating window via jar testing and then set routine controls for stable performance.
- pH and alkalinity control (impacts coagulation efficiency)
- Mixing energy and flocculation time (impacts floc size/settling)
- Sludge volume/handling strategy (affects total treatment cost)
Technical overview
Aluminum Sulfate hydrolyzes in water to form aluminum hydroxide species that help neutralize particle charges and form flocs, improving clarification and solids separation. It can consume alkalinity and influence pH, so process control typically considers alkalinity, pH setpoints, and downstream filtration performance.
Core function
Coagulation and floc formation for turbidity/color reduction and clarification.
Process integration
Typically used with rapid mix + flocculation + settling/DAF + filtration (system dependent).
Operational notes
Dose optimization via jar tests; monitor pH/alkalinity and manage sludge output and handling.
Typical dosing ranges (starting points)
Actual dosing depends on water chemistry and treatment targets. The ranges below are indicative only and should be confirmed by your treatment team via jar testing and plant trials.
| Application | Typical role | Typical range* | Notes |
|---|---|---|---|
| Drinking water clarification | Primary coagulant | ~5–80 mg/L (as product basis) | Varies with turbidity/color and temperature |
| Wastewater / industrial effluent | Coagulant / clarification support | ~20–300 mg/L (as product basis) | Confirm with jar tests; solids load drives dose |
| Paper/process water | Process control use cases | Case dependent | Confirm compatibility with your process chemistry |
*Illustrative starting ranges only. Final dosing should be set by jar testing, trials, and your internal operating standards.
Typical specifications & formats

Storage & handling (summary)
Store in a dry, well-ventilated area. Keep solid product sealed to prevent moisture pickup and caking. For liquid grades, confirm material compatibility for tanks/pumps and use appropriate spill containment. Follow SDS guidance for safe handling and PPE.
- Keep containers sealed; protect from moisture and contamination
- Use compatible materials for liquid storage and dosing equipment
- Follow local safety practices for acidic inorganic salts and solutions
Specifications may vary depending on batch, origin, and packaging selection. The offer and COA are the controlling documents.
FAQ
Quick answers to common procurement and technical questions.
Alum vs. PAC — what’s the difference?
PAC is a pre-hydrolyzed aluminum coagulant that can offer different performance windows and operating behavior depending on the water. Many plants compare both via jar tests and select based on dose, sludge, pH impact, and total operating cost.
Solid vs. liquid Alum?
Liquid grades simplify dosing and reduce make-down steps, while solids can be economical for certain supply lanes and storage setups. The best choice depends on your infrastructure, labor, and logistics.
Can you provide SDS/COA/TDS?
Yes—SDS and COA are available on request and can be provided per shipment/grade. TDS and extended QC parameters can also be requested.
Why does pH matter?
Coagulation performance depends strongly on pH and alkalinity. Alum can consume alkalinity and shift pH, so many systems monitor and adjust operating conditions to maintain stable results.
How do I estimate monthly usage?
Share your treated flow rate, typical dose range, operating hours, and product strength (solid vs. liquid). We can help convert this into monthly procurement volume.
Any storage concerns?
Keep solids dry and sealed to prevent caking. For liquids, use compatible tanks/pumps and good containment practices. Follow SDS guidance for safe handling.
