What is the acceptable range of post hardness in water used for dialysis?

The acceptable range of post hardness in the water used for dialysis is critical to ensure the safety and effectiveness of the treatment. Water hardness is primarily a measure of the concentration of calcium and magnesium ions in the water. In hemodialysis, excessive hardness can lead to complications, such as scaling in the dialysis equipment and potentially impacting patient care.

The value of 0.8 grain per gallon is recognized as the maximum acceptable level for post hardness in dialysis water. This specific threshold is established to minimize the risk of any adverse effects associated with harder water while still allowing for sufficient processing and proper functioning of dialysis equipment. Keeping the hardness within this limit helps maintain the integrity of the dialysis machines and ensures patient safety by preventing mineral build-up that could compromise the filtration and treatment process.

Values above this threshold could introduce problems that are best avoided, which is why 0.8 grain per gallon is considered optimal for post-treatment hardness in dialysis water.
