Towards zero liquid discharge in hemodialysis. Possible issues.

Scarcity of water and energy, and legal requirements for discharge of waste and wastewater are forcing hemodialysis facilities to change their approach to a more integrated concept of connecting the residual output (in terms of waste, wastewater and energy loss) to the input (in terms of water and energy). Zero liquid discharge is an expanding water treatment philosophy in which hemodialysis wastewater is purified and recycled, leaving little to no effluent remaining when the process is complete, thereby saving money and being beneficial to the environment. This article explores the possible ways to treat hemodialysis wastewater, thus achieving ZLD conditions.

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.

Current understanding of ozone use for disinfecting hemodialysis water treatment systems.

Background: Water treatment systems are susceptible to microbial contaminations and periodical disinfection procedures are mandatory to obtain results requested from international standards. According to the Association for the Advancement of Medical Instrumentation, ozone is the most effective method to destroy microorganisms, and to prevent, reduce or remove the biofilm. This study aims to review the literature on the application of ozone in the disinfection of water treatment systems for hemodialysis.

Recycling wastewater after hemodialysis: an environmental analysis for alternative water sources in arid regions.

Water is a vital aspect of hemodialysis. During the procedure, large volumes of water are used to prepare dialysate and clean and reprocess machines. This report evaluates the technical and economic feasibility of recycling hemodialysis wastewater for irrigation uses, such as watering gardens and landscape plantings.
