Invitation to Attend "Impact of Naturally Occurring Radioactive Materials in Water on Your Carbon Filters" Seminar

You are invited to a free educational seminar on how treating drinking water with naturally occurring radioactive materials (NORM) can lead to activated carbon landfill disposal problems in as little as 7 months.

The seminar will be held March 6 at 9:00 AM at the Res-Kem-Aston, PA facility.

Why should you attend?

If your company uses activated carbon for the treatment of private well ground water for your plant's needs, remediation of ground water for VOC contamination, sulfur removal, radon reduction, this seminar has critical information that may impact the way you conduct your carbon exchange program.


Do you have is this problem? It depends.  There is a rock formation found in the region from central Pennsylvania through New England. Carbon filters can "Technically Enhance" the naturally occurring radioactive materials (TENORM) to a level exceeding landfill allowable radiation levels.

Activated Carbon-"That Old Black Magic"

Activated carbon is an amazing product. Its ability to purify and remove contaminants seems limitless. However, few people know what activated carbon really is or how it's manufactured. One of my go to articles on the subject, written by Calgon Carbon, is "Activated Carbon. What is it, How Does it Work".

What is activated carbon made from?
Just about anything organic can be reduced to its elemental carbon. We use the term activated because the organic material must be changed or carbonized to gain necessary pour structure to make it adsorb. Carbon manufacturers who serve the potable water and waste water markets found that coal, wood, and coconut char are the most suitable for the activation process.


How is activated carbon "activated"?
After the base material is selected an graded, it is sent to a huge furnace or "kiln" where it is blasted with 800 to 1000 degree heat. Through the miracle of science, and closely held cooking secrets, out pops the wonderful product known as activated carbon. Depending on the raw material used, finished carbon has a dry packed density from 27.5 to 33 pounds per cubic foot.


What should I look out for?
When purchasing activated carbon please remember quality can vary greatly. Garbage in, garbage out. Stick with a manufacturer or distributor you can trust. Also, since coal and coconut char are a commodity product, they are subject to to market supply and demand forces. Recently supply shortages have driven the price of coconut carbon up 35%.
