1 PRODUCT DESCRIPTION AND CHARACTERISTICS
2 METHODS OF SUPPLY AND DELIVERY
1.3.3 Crystallisation Temperature
1.1 Description
Liquid Aluminium Sulphate is supplied as a saturated
solution with the empirical formula:
Al (SO ) .51.8 H O2 4 3 2
This may be alternatively expressed as :
Al O .3SO .51.8 H O2 3 3 2
The Al O content of the product is 8% w/w – hence the 2 3
Industry Standard description of the product as ‘8%
Aluminium Sulphate’.
In Aluminium terms the product contains 4.2% w/w,
and as Aluminium Sulphate it contains 26.8% w/w.2.1 Bulk Tanker
Normal supply is by articulated bulk air pressure road 1.2 Characteristics
