Water treatment for hemodialysis
Hemodialysis is a purification process used in acute or chronic kidney failure to remove harmful substances from patients' blood. In hemodialysis, up to 25,000 litres of dialysis fluid are used per patient per year. This dialysate consists of over 97 % pure water.
Water treatment therefore plays a central role in hemodialysis treatment. A suitable dialysate preparation system must guarantee maximum safety for the patient, enable reliable operation of the dialysis centre and be economical with resources by minimising water and energy consumption.
Our complete system for dialysis water treatment is designed to meet the highest hygiene requirements and ensure operational safety as well as minimal operating costs.
From pre-treatment to single-pass and double-pass reverse osmosis systems to dead-zone-free loop systems and state-of-the-art single or double dialysis stations – we can supply you with the best possible technology based on our many years of experience in the field of dialysis water treatment.
In order to meet the highest hygiene requirements, we offer systems with thermal disinfection of the complete reverse osmosis unit including the feed tank, the membrane modules, the loop and the dead-zone-free feed hoses for dialysis machines.
Herco's most efficient dialysis water treatment complies with MDR requirements. The MDR certificate valid since February 17, 2023, was issued by TÜV SÜD Product Service GmbH.
“We have been working with our reliable partner Herco Medical since 2016; with them we have realised two of our largest and most state-of-the-art dialysis centres in Ilion and Patra. Both are equipped with the latest technologies and thus offer the most widely known and most reliable dialysis treatments currently available. As always, collaborating with Herco was great.”

Example RO series:
Dead zone-free ultrapure water system for haemodialysis
Our hot-sanitisable double-stage RO units of the "HP5500D" series are compatible with dialysis machines of all well-known manufacturers. The units of this series reduce operating costs through a triple water saving strategy and high energy efficiency.
Advantages of the RO series "HP5500D"
+ Reduction of water consumption up to 35%*
Recirculation of the permeate from the circuit, adjustment of the concentrate flow in the 1st stage according to the current permeate consumption, and the return of concentrate from the 2nd stage to the break tank.
+ Disinfection at the push of a button
The complete RO system including the modules can be sanitised at a temperature of up to 90°C. Optionally, the entire dialysis water system can be hot-cleaned in the same step. Herco confirms the quality as a medical product and hereby guarantees absolute safety for the treatment of patients.
+ Long lifetime
The stainless steel piping and a robust stainless steel base frame, as well as a leakage detection system and process-related alarm messages, ensure a long service life for the system.
+ Excellent ultrapure water quality
The double-stage design, the dead space-free construction and the possibility of thermal (chemical-free) disinfection result in excellent dialysis water quality.
+ Operating safety through monitoring
The storage and display of all relevant operating data, support and maintenance by the Herco service team and, last but not least, tested quality through the 'MDR Certificate' issued by TÜV SÜD Product Service GmbH.
