Acid Alum


Acid alum can be used in municipal and industrial water treatment applications to remove turbidity, color, suspended solids and oil (emulsion breaking). 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.  It is commonly used in the paper industry for pitch control.  Acid Alum is also used in poultry houses as a litter amendment for ammonia control.

Benefit from Reduced Operating Costs

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. Another benefit of our 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.
