Robert Potwora writes article in Water Quality Products Magazine

The March issue of Water Quality Products magazine contains an article written by Robert Potwora titled, “The ABCs of Activated Carbon”.  The characteristics of activated carbons produced from coconut shell, bituminous coal, sub-bituminous coal and lignite coal are covered in detail.  The ash content is a very important parameter for activated carbons.  Some coal based activated carbons may contain ash greater than 30%.  Selecting a purer coal and/or washing the coal based activated carbon can reduce ash levels to 10 – 15%.  Whereas coconut shell activated carbons like Sabre series® C grade have an ash content of 2 – 3 % without washing.  The lower ash content and washing helps minimize impurities that may leach off the activated carbon into the water being treated.   Selecting the right particle size is also critical for proper performance of point-of-use (POU) and point-of- entry (POE) carbon systems.
