SWT logo ProActive™ Acid-Washed 20 x 50 Carbon

ProActive™ Acid-Washed 20 x 50 Granular Activated Carbon is made from a superior quality anthracite and non-viscous coal with naturally low ash, low sulphur and phosphorous content. It is manufactured through high temperature steam activation under stringent quality control. It has a large surface area, high pore volume, high mechanical hardness and chemical stability, longer operating life, and it is easy to regenerate. It is used in liquid purification, filtration, and water treatment for the removal of organic contaminates, odor, taste, color, and turbidity. The product meets the standards of Food and Chemical Codex for activated carbon.

Warning
For safety and handling purposes, we recommend appropriate protective measures when entering a wet vessel containing granular activated carbon, because wet activated carbon depletes oxygen from air and therefore, dangerously low levels of oxygen may be encountered. In such a case, the oxygen level inside the vessel shall be determined before entering and appropriate protective equipment should be worn when entering, or leave the vessel open until the oxygen level in the vessel is normal.
