Serim® GUARDIAN™ WATER HARDNESS Test Strips provide a convenient means for indicating the level of hardness in water at the post-softener stage of the water treatment process in dialysis clinics, hospitals, food production, etc. Hardness is described as the total concentration of calcium and magnesium, expressed as ppm or grains/gallon of calcium carbonate (CaCO3). According to the US Geological Survey (USGS) water hardness scale: Soft water = 0 – 60 mg/L or 0 – 3.5 GPG; Moderately hard water = 61 to 120 mg/L or 3.5 – 7 GPG; Hard water. Total chlorine tests measure the total of the amount of free chlorine and combined chlorine/chloramines in the water under test. Consequently, total chlorine tests do not measure chloramines separately. Per the AAMI RD62 Standard, free chlorine in dialysis feed water at levels above 0.5 mg/l (ppm) may also cause. Most people on hemodialysis are limited to approximately 32 to 50 fluid ounces per day, compared to a fluid intake of 100 ounces daily for someone who has working kidneys.
