Aluminum Sulfate (Alum)

GAC's high performance iron free alum is used in papermaking, and is considered the industry standard. Its ultra clear grade is used in the photography industry as a fixer. The technical and NSF certified grades are used in the potable and wastewater municipal markets. GAC reacts sulfuric acid with aluminum trihydrate to produce the various grades of alum. Each of the grades has raw material specifications, processing parameters, and quality requirements including some "ultra" filtration.


GAC packages and ships alum in railroad tank cars, tank trucks, single and multi trip tote tanks, and drums. Custom packaging is available.


GAC has all products in bulk inventory and can ship 24/7*.
