ACUMER™ 4300

Acumer™ 4300 is manufactured by DOW Chemical (Mid South Chemical is a “certified” repackager of Acumer™ products)

 

Scale Inhibitor and Dispersant Superior scale inhibitor and dispersant for calcium carbonate and sulfate control in water systems

Description

ACUMER™ 4300 is a high performance scale inhibitor, specifically developed to prevent both calcium carbonate and calcium sulfate salt deposits in water systems. The unique feature of ACUMER 4300 is the improved overall performance for inhibiting these calcium scales over conventional polymaleic acids, acrylate polymers and phosphonates. This product, a maleic multipolymer, will also prevent the formation of other scales such as calcium oxalate. ACUMER 4300 will also disperse colloids and fine particles such as clay.

Mechanisms of Action

Maleic polymers are known to be excellent calcium carbonate inhibitors and crystal modifiers but many exhibit only fair calcium sulfate deposit control. A new polymer, ACUMER 4300, has been developed to overcome this problem. ACUMER 4300 contains maleic and a unique combination of other functionalities to provide both superior calcium carbonate and calcium sulfate inhibition, also outperforming HEDP. Preventing calcium sulfate scale is important in water systems treated with sulfuric acid for pH control or if using seawater or briny waters. Also removing sulfur oxide gases in scrubbing systems can result in sulfur containing calcium deposits.

ACUMER 4300 polymer inhibits scale buildup on surfaces through at least three mechanisms:

  • Solubility enhancement or threshold effect, which reduces precipitation of low solubility inorganic salts.
  • Crystal modification, which deforms the growing inorganic salt crystals to give small, irregular, readily fractured crystal that do not adhere well to surfaces.
  • Dispersing activity, which prevents precipitated crystals or other inorganic particles from agglomerating and depositing on surfaces.
