aluminum sulfate (alum)

Chameleon Industries manufactures and supplies the highest quality aluminum sulfate.  Our aluminum sulfate - more familiarly, alum - is produced by dissolving alumina tri-hydrate (ATH) into sulfuric acid and water to produce a superior quality, iron-free solution.


Aluminum sulfate is one of the most widely used industrial chemicals, playing an important role in the production of many essentials seen and used every day in homes and industry. Uses for aluminum sulfate include:

​

  1. Potable Water Treatment

  2. Waste Water Treatment

  3. Paper mills

  4. Dye 

  5. Fire Extinguisher Foam

  6. Soil Additive

  7. Synthetic catalyst production

Packaging and delivery

Chameleon Industries provides aluminum sulfate in bulk truckload quantities to municipalities and industry.  We utilize our dedicated truck fleet to ensure quality and responsiveness to our customers throughout Texas and surrounding regions.  



Waste WATER TREATMENT

Alum is also used by some municipalities for the treatment of waste water.  Its purpose is twofold:


  1. As in water purification, to coagulate the suspended and colloidal particles of the sewage.

  2. For conditioning of sewage sludge on sludge-drying beds.


When alum is added to waste water, it forms a floc which envelops and absorbs both the suspended particles and colloidal matter.  Coagulation is faster than in the purification of potable water because the concentration of solids is higher in sewage.


Pulp & paper

A majority of all alum produced is consumed by the pulp and paper industry.  The main functions of alum in papermaking are to precipitate the dissolved rosin in the size on the fibers of the paper and condition the water of the stock system.

POTABLE WATER TREATMENT

There are a variety of primary coagulants which can be used in a water treatment plant.  One of the earliest coagulants, and still the most extensively used, is aluminum sulfate.  When alum is added and mixed with the raw water, it reacts with the alkalinity to form gelatinous flocs of aluminum hydroxide which absorb and entangle the colloidal organic impurities present.  The floc settles out and the resulting water is often clear, colorless, and odorless.  Alum is an excellent primary coagulant for removing:


     • Turbidity

     • Total organic carbon (TOC)

     • Suspended solids

     • Biochemical oxygen demand (BOD)
