Dialysis
Puragen provides critical water purification technology for hemodialysis clinics. High purity carbon products efficiently remove chlorine, chloramine and other organic contaminants from water to protect dialysis membranes.
Puragen’s filtration media safeguard patient health and ensure compliance with stringent medical water quality standards including the British Standards Institute (BS EN 23500) and meet the Association for the Advancement of Medical Instrumentation (AAMI) standards.
Dialysis water purity requirements are among the most demanding of any water treatment application, and carbon selection must account for chloramine breakthrough, bed exhaustion rates, and the risk of carbon fines entering the water system. Puragen’s technical team works with clinic operators and equipment suppliers to specify the correct carbon grade, vessel configuration, and exchange schedule for each installation. All products are supplied with full documentation to support regulatory compliance and quality assurance processes.
Contaminants we remove
Puragen’s dialysis applications ensure the highest level of dialysis water purity by adsorbing harmful contaminants.
Activated carbon products for Dialysis
Puragen provides a comprehensive range of premium activated carbon solutions for dialysis purification, ensuring efficient contaminant removal and long-term cost savings. Dialysis water purity requirements are among the most demanding of any water treatment application, and carbon selection must account for chloramine breakthrough rates, bed exhaustion, and the risk of carbon fines entering the water system. Puragen’s technical team works with clinic operators and equipment suppliers to specify the correct carbon grade, vessel configuration, and exchange schedule for each installation. All products are supplied with full documentation to support regulatory compliance and quality assurance processes.
Granular Activated Carbon (GAC)
High-purity, high-capacity acid-washed carbons, for applications where water is passed through a fixed but refillable bed of carbon in granular form.
Mobile filters for Dialysis
Puragen’s range of mobile filters are optimised for a variety of liquid phase applications. We can adapt our filters to integrate with any specific site installation requirements.
Mobile filtration is particularly suited to dialysis applications requiring temporary capacity, clinic relocations, or bridging treatment during fixed system maintenance or carbon exchange. Puragen’s AquaSorber units are pre-commissioned and arrive ready to connect, minimizing disruption to clinic operations. Carbon loading, exchange scheduling, and spent carbon removal are all managed by Puragen, with no on-site waste handling required from clinic staff.
AquaSorber 2-SX
Maximum Flow Rate (m3/hr): 12
AquaSorber 5
Maximum Flow Rate (m3/hr): 20

Frequently Asked Questions
Activated carbon is the standard method for removing chlorine and chloramine from water before it enters a dialysis system, as both compounds can cause serious harm to patients if present in dialysate. GAC beds provide continuous, high-capacity adsorption at the flow rates typical of hemodialysis clinics, and are required as part of water treatment train designs that comply with AAMI and BS EN 23500 standards. Puragen supplies dialysis-grade carbons specifically selected for their purity, adsorption capacity, and low extractables profile.
Dialysis water quality in the US is governed by AAMI standards, which set maximum allowable levels for chemical contaminants, microbial content, and endotoxins in water used for hemodialysis. These standards require that chlorine and chloramine be reduced to non-detectable levels before water contacts the dialyzer membrane. Puragen’s GAC products are selected and documented to support compliance with these requirements.
Exchange frequency depends on the chloramine concentration in the incoming water supply, the flow rate through the carbon bed, and the bed volume specified for the installation. Most dialysis facilities monitor for chloramine breakthrough continuously and schedule carbon exchange based on measured bed exhaustion rather than fixed intervals. Puragen can assist with sizing calculations and exchange scheduling to ensure uninterrupted protection throughout the carbon service life.
Chloramine breakthrough occurs when the carbon bed becomes exhausted and can no longer adsorb incoming chloramine, allowing it to pass into the dialysis water system. Because chloramine cannot be removed by reverse osmosis membranes alone, a failure in the carbon stage poses a direct risk to patient safety. Redundant carbon vessels operated in series, combined with continuous online monitoring, are the standard safeguard against breakthrough events.
Yes. Puragen supports dialysis facilities at all stages, from initial carbon specification and vessel sizing through to scheduled exchange programs and emergency supply. Our integrated logistics network is designed to deliver carbon reliably against the exchange schedules that clinic operations depend on, with full documentation provided for quality and compliance records. Contact Puragen to discuss supply arrangements for your clinic or network of facilities.
