Mini-cores of activated carbon block simulate full-sized performance for removing organics and arsenate from drinking water^✰.

ABSTRACT: Activated carbon block (ACB) filters are widely used in point-of-use (POU) drinking technology to remove tastes, odors, and organic compounds from drinking water, and when modified can even remove inorganic pollutants (e.g., arsenate, lead, copper). To introduce ACB technologies to the POU market, thorough assessment and testing are required to meet the National Sanitary Foundation 53 certification. Testing to gain this certification can be costly and time-consuming and is usually only done on the final product before commercial distribution. We developed and explored how a cylindrical "plug" cored from an ACB can be used in a mini-core apparatus with low water volumes, to mimic full-sized ACB performance. These mini-cores allow the same outside-in radial flow conditions as the full-sized
