Ultraviolet (UV) dechlorination technology from Hanovia is assisting in the ongoing treatment of patients with kidney disease at the Hospital of St Cross in Rugby, Warwickshire, UK.

Hanovia’s PharmaLine DC UV system helps to purify the water used in dialysate fluid for renal dialysis, by lowering the amount of chlorine present.

Purified water plays a fundamental role in the provision of renal dialysis for patients with chronic kidney disease. More than 99% of the dialysate fluid used in the procedure is composed of purified water, and the key purification process in this application is reverse osmosis (RO).

Treatment barrier

The renal water treatment system at the hospital was previously using activated carbon filtration (ACF) for chlorine removal prior to the RO process. However, the water’s high total organic carbon (TOC) concentration challenged the capacity of the ACF to remove chlorine,

However, Hanovia's s PharmaLine DC UV system not only helps control the level of chlorine, but also provides a treatment barrier for any microbial contamination. The UV dechlorinated the renal dialysis water and delivered the desired < 0.1 ppm of total chlorine in the feed water to the ACF and RO units.
