Hemodialysis water systems

Of all the medically-related applications for Pure Water, hemodialysis and particularly HDF online are probably the most dynamic in terms of recent development.

The application is not purely concerned with removing bacteria from the water supply. As hemodialysis patients process extremely large quantities of water it is vital that trace impurities are removed from the water in the dialysate, otherwise they would accumulate hazardous levels of toxins in the bloodstream. The fact that large quantities of water are consumed also, inevitably, has consequences from the aspect of operating cost and efficiency.

Clearly, as hemodialysis becomes more widely available, the advantage of providing the necessary water quality using compact, on-site systems continues to grow. For Pure Water Group, providing solutions for hemodialysis and HDF online has become a specialist subject of expertise over the past 20 years.

Specifications – While all hemodialysis equipment and renewables, including water treatment systems, must be of high quality, these are governed by different standards around the world. In the Netherlands, the normal purification following pre-treatment is by 2-stage RO and UF, sometimes with EDI to ensure compliancy with EP WFI requirements. Typical variations for night time treatment (or even 24/7 dialysis treatment availability) include three pass RO with UF and two pass RO with EDI and UF.
