Aluminum Sulfate (Alum)

Aluminum Sulfate (Alum) is a widely-used and versatile industrial chemical, playing an important role in the production of many essentials seen and used every day in the home and industry.

Most of the alum produced today is used in the pulp & paper industry as well as water and wastewater treatment.  It is inexpensive and effective for a broad range of treatment problems because it can function as a coagulant, flocculant, precipitant and emulsion breaker. As a coagulant and flocculant, alum removes turbidity, total organic carbon (TOC) which can be disinfection byproduct precursors, suspended solids and colloidal color, reduces biochemical oxygen demand (BOD) and clarifies potable, process and wastewater.

Alum is widely used for lake restoration, treatment and nutrient inactivation.  It also is used in the production of aluminum chemicals, fire extinguisher compounds, soil additives and fertilizer, soaps, greases, drugs and cosmetics.  It even enters into the sports arena, as an additive to give major league baseball covers their hard, tough hides.

In short, alum touches the lives of just about everyone in many ways.
