Description:
Aluminum Chlorohydrate Solution (ACH) is a highly concentrated solution of polyaluminum hydroxychloride. It is characterized by having the highest aluminum concentration (23% Al2O3) of any commercially available aluminum based solution. The basicity of ACH at 83% is also the highest available for any polyaluminum based solution. Basicity refers to the degree of acid neutralization and also represents a measure of how highly polymerized the aluminum in ACH is.

The highly polymerized aluminum species in ACH have much higher cationic charges than the aluminum in standard salts such as alum or aluminum chloride, and even other polyaluminum products. Therefore, ACH can offer both a higher level of performance and lower overall dosages. The high degree of acid neutralization (basicity) also means that the effect on pH when applying ACH will be negligible. ACH also effectively coagulates over a broader pH range (as high as 9.5) versus traditional metal salts and lower basicity Pacl.

Applications and Benefits:

• Municipal and Industrial Water Treatment
  Aluminum Chlorohydrate Solution is generally employed as the primary coagulant in potable water and industrial water treatment plants, replacing the need for other coagulants such as alum, and in many cases also eliminating or at least greatly reducing the need for pH adjustment chemicals, coagulant aids and filter aids. ACH is often employed in an environment where the pH of the receiving stream is higher than 7.5.

  Consistently recognized benefits of converting to Aluminum Chlorohydrate Solution are:
  - Improved turbidity removal
  - Improved color removal
  - Increased TOC (Total Organic Carbon) removal
  - Lower filter turbidities
  - Increased filter run length
  - Sludge reduction of over 50%
  - Simplified operations by eliminating pH and secondary polyelectrolyte feed
  - Lower overall treatment costs

• Municipal and Industrial Wastewater Treatment
  Aluminum Chlorohydrate Solution is also used in wastewater treatment applications for:
  - TSS (Total Suspended Solids) removal
  -Metals removal
  -Phosphate removal
  - COD (Chemical Oxygen Demand) reduction in industrial wastewater treatment
  - BOD (Biological Oxygen Demand) and TOC (Total Organic Carbon) removal in municipal wastewater treatment
• Pulp and Paper - On Machine
  Aluminum Chlorohydrate Solution is also used in several on machine applications as a:
  - Size bonding agent
  - Anionic trash scavenger
  - Retention and drainage aid
  - Pitch control additive

Safety:
Aluminum Chlorohydrate Solution is a slightly corrosive mineral acid that has the following ratings:
Health Rating: 1-Slight
Flammability Rating: 0-None
Reactivity Rating: 1-Slight
Contact Rating: 1-Slight
Protective Equipment: Goggles, Long Sleeves and Gloves

Thoroughly read and understand the information presented in the Material Safety Data Sheet prior to using Aluminum Chlorohydrate Solution in laboratory, pilot plant and/or full plant applications.

Storage and Handling:
Storage tanks and piping for Aluminum Chlorohydrate Solutions should be constructed of materials recommended for corrosive products. FRP, PVC, HDPE and/or rubber are the materials of choice for piping and storage tanks. Metering pumps and other equipment that comes in contact with concentrated solutions of Aluminum Chlorohydrate must also be constructed of acid resistant materials such as PVC, rubber, Teflon, ceramic and Hastolly C. No wetted parts should contain any metals such as carbon steel, stainless steel, brass or aluminum.
