SuperCat™ Coconut Shell Carbon

ProActive™ 12 x 40 SuperCat™ Coconut Shell Carbon is a dual-function activated carbon. It offers a high activity for the removal of both chloramines or chlorine from water, while, at the same time, it retains the inherent superiority of coconut shell carbons for removing trace organics. Like other coconut carbons, it has a higher hardness, lower dust level, and lower levels of soluble ash than standard coal-based carbons. ProActive™ SuperCat™ Coconut Shell Carbon is a registered product under ANSI/NSF Standard 61.
   

Catalytic Chloramine Removal
Many municipalities now use chloramines instead of chlorine to disinfect water supplies; chloramines can also form after conventional chlorination via reaction with nitrogen containing organics. Because standard activated carbons do not remove chloramines well, SWT is introducing this surface-modified carbon, designed specifically to catalyze monochloramine (NH2Cl) decomposition.

Trace Organic Capacity
ProActive™ SuperCat™ Coconut Shell Carbon, a highly microporous carbon, also offers superior removal of chloroform, THM, and MTBE when compared to coal-based carbons.



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.

Performance Comparison
The left figure shows an accelerated test of ProActive™ SuperCat™ Coconut Carbon and a coal-based catalytic carbon. Standard 9 x 2.5 inch water filter cartridges containing granular carbon were tested at 1 gpm water flow (11 sec. empty bed contact time). At higher empty bed contact times (>2 min), ProActive™ SuperCat™ Coconut Carbon reduced monochloramine from 3 ppm to non-detect levels.
