Choosing a tank
What to Look for in a Aluminum Sulfate (Alum) Tank
Weight
48% liquid alum weighs about 1.3 times as much as water. The tanks on this page are rated 1.5 SG or higher.
Cold weather
Alum solution freezes at about 4°F, and concentrated alum held cold can form crystals. Outdoor tanks in cold climates may need insulation.
Containment
Its low pH makes a spill a cleanup problem. Plan secondary containment.
Compatibility
Tank Materials for Aluminum Sulfate (Alum)
Ratings from our chemical compatibility database: A = excellent, B = good, C = fair. Ratings assume room temperature; send us your concentration, temperature and SDS to confirm. Compare resins in our tank resin guide.
| Tank resin | Rating | Notes |
|---|---|---|
| HDPE | A | The economical choice. |
| Polypropylene | A | Also suitable. |
| PVDF | A | More than alum usually needs. |
Fittings
Liquid alum is acidic (pH around 2), so plastic fittings are the usual choice. Tell us your fitting needs and we will specify them. See our fittings and options.
Gaskets

SG (specific gravity) is the heaviest liquid a tank is built to hold. Water is 1.0, so a 1.9 SG tank is made for liquids up to 1.9 times as heavy as water. Choose an SG rating at or above the specific gravity of your liquid. See our specific gravity chart.
Bailiff-molded HDPE vertical tanks of 500 gallons and larger meet or exceed ASTM D1998-21 wall thickness requirements.

Safety data
Aluminum Sulfate (Alum) Hazards at a Glance
Liquid alum is acidic and causes serious eye damage; avoid skin contact. It is often shipped as a corrosive liquid (DOT Class 8).
This is a short summary, not a safety data sheet. Always follow the SDS from your chemical supplier for handling, protective equipment and first aid.

FAQ
Aluminum Sulfate (Alum) Tank Questions
What tank is used for liquid alum?
HDPE, polypropylene and PVDF are all rated A for aluminum sulfate in our compatibility database. HDPE is the most economical. Because 48% alum has a specific gravity of about 1.3, choose a tank rated 1.5 SG or higher.
Does liquid alum freeze?
Aluminum sulfate solution freezes at about 4°F, and concentrated alum held cold can crystallize. Outdoor tanks in cold climates may need insulation.
