USALCO provides Acid Alum in bulk truckload quantities for municipalities and industrial users. We use dedicated trucks to insure quality and have multiple plants to meet your needs.
USALCO Acid Alum, Aluminum Sulfate acidized with 7% free acid, is a high quality, iron-free, clear solution that meets or exceeds the specifications of the American Water Works Association Standard B403-09 and complies with the requirements of NSF/ANSI Standard 60: Drinking Water Treatment Chemicals – Health Effects at a maximum dosage of 150 mg/L.
Acid alum can be used in municipal and industrial water treatment applications to remove turbidity, color, suspended solids and oil (emulsion breaking). It is commonly used in the paper industry for pitch control. USALCO Acid Alum is especially effective in water treatment applications where TOC (total organic carbon) removal is important. It produces a more dense and settleable floc than water treated with a comparable amount of standard alum. Acidified alum also reduces the residual soluble aluminum in treated water.
One benefit typical with the acid alum product is a marked improvement in the settled water filterability as less sludge is typically produced. The result is higher quality water at a reduced operating cost.
USALCO Aluminum Sulfate is widely used because it is a cost-effective, clear solution that mixes well in water treatment. It does not add color to the water treatment process.
The USALCO manufactures iron free Alum by dissolving alumina tri-hydrate (ATH) into water and sulfuric acid.
