Independent Lab Study Shows TIGG Activated Carbon Removes TTHMs


A recent study conducted by an independent environmental laboratory proves that TIGG’s 5DC 1230 activated carbon is effective at removing TTHMs from municipal drinking water. The test was sponsored by a municipality that needed to come into compliance with the EPA’s DPB Stage 2 regulations.

The study sponsor historically had high levels of TTHM in its water that ranged between 105 and 171 µg/L. The municipality talked to TIGG about a water purification adsorption system. While some in the industry insist that coal-based activated carbon is the most effective means of removing disinfection byproducts from municipal drinking water, TIGG experts recommended their 5DC 1230 virgin coconut activated carbon.

The municipality had an independent laboratory run a pilot study using a rapid small-scale column test. They used TIGG’s 5DC 12 x 30 NSF activated carbon, which is designed to remove low concentrations of contaminants from potable water. The laboratory found that initial TTHM concentrations of 138 µg/L were reduced to < 1.0 µg/L following treatment with virgin coconut activated carbon. Based on the scale-up of the testing, it was determined that a full scale carbon adsorber would effectively treat TTHMs for 325 days before the bed needed a changeout.

Not only is coconut-based activated carbon effective, it is typically more economical than coal-based activated carbon. The report shows the laboratory’s results over a 24-day period.
