Conventional hemodialysis (CHD) patients are typically exposed to more than 400 L of water each week, while for home hemodialysis (HHD) water exposure can vary from 150 L to significantly more than 400 L per week depending on the HD prescription and the dialysis system.1 There are many substances that must be removed from the water supply to make it safe for dialysis. Water purification systems consist of a series of components that remove contaminants via different mechanisms. Regular monitoring of its components and of the product water is essential for ensuring proper function of the water system.2 Failure to adequately treat the water supply can lead to serious adverse effects, including death.3,4 While water standards are the same for CHD and HHD, some of the dialysis systems used for HHD differ from conventional machines. Water treatment is reviewed in this chapter with a focus on issues specific to HHD.
