https://www.myronlproducts.com/index.php?main_page=page&id=3...Carbon adsorption is typically used for the removal of chlorine disinfectant present in the feed water. Both free chlorine and chloramine levels must be controlled. The presence of these contaminants in hemodialysis solution could lead to hemolysis, resulting in death to patients. Removal of chlorine and chlorine compounds also prevents degradation of reverse osmosis (RO) filters used downstream in the water treatment system. In hemodialysis clinics, two carbon tanks are required. Carbon adsorption must be checked at the beginning of each treatment day, before each patient shift or every 4 hours, with samples being drawn after at least 15 minutes of operation. Samples are taken from testing ports following each tank, with action required if the second testing port is positive. The accidental use of expired reagents or test strips or ones not sensitive enough to detect unsafe chlorine levels can create errors in detection. The D-6 Dialysate Meter ORP function does not require the use of reagents or test strips and generates extremely accurate objective digital results.
