  1. Water Conservation: An Emerging but Vital Issue in Hemodialysis Therapy

    Water conservation refers to reducing the usage of water and recycling of wastewater for different purposes such as irrigation, laundry and sanitation. As water scarcity increases worldwide, dialysis facilities should be focused on salvaging water. However, most of them still ignorantly discard to the sewer huge volumes of this reusable resource. This article reviews the current water conservation techniques in hemodialysis and the potential benefits drawn when using this technology. Tarrass F, Benjelloun M, Benjelloun O, Bensaha T. Water Conservation: An Emerging but Vital Issue in Hemodialysis Therapy. Blood Purif. 2010 Oct 6;30(3):181-185. PMID: 20924173

  2. Toward greener dialysis: a case study to illustrate and encourage the salvage of reject water

    A Connor, S Milne, A Owen, G Boyle, F Mortimer (2010). Journal of Renal Care, 36(2), 68-72. Climate change is now considered to be a major global public health concern. However, the very provision of health care itself has a significant impact upon the environment. Action must be taken to reduce this impact. Water is a precious and finite natural resource. Vast quantities of high-grade water are required to provide haemodialysis. The reverse osmosis systems used in the purification process reject approximately two-thirds of the water presented to them. Therefore, around 250 litres of 'reject water' result from the production of the dialysate required for one treatment. This good quality reject water is lost-to-drain in the vast majority of centres worldwide. Simple methodologies exist to recycle this water for alternative purposes. We describe here a case study of the only UK renal service we know to have implemented such water-saving methodologies.

  3. Case study and how-to guide: conserving water in haemodialysis

    When the Canterbury dialysis unit updated its water purification system with the installation of a new reverse osmosis plant in 1997, it was soon apparent that large volumes of reject water were being ‘lost to drain’. Within two years, and with the help of the hospital’s Estates Department, a simple system capable of recycling 800 litres of this water per hour was installed at a cost of £15,000. The system has now been running for over ten years, saving the Trust £7,500 each year on mains water and sewerage costs. Green Nephrology programme, 2009-2010
