We offer solutions for renal dialysis, including compact systems for home use and high volume systems for multi-bed wards, plus advanced water purification systems for clinical analyser feed, decontamination and sterile services departments.

In addition, we supply wall mounted and benchtop reverse osmosis water purification units, low cost deionisation cartridges, and centralised, modular high volume water purification systems for feeding laboratory ring-mains.

Our proven technology produces purified and ultrapure water, to 18.2 MΩ.cm, and meets the requirements of BS EN ISO 3696 and ASTM D1193-06 standards.

We offer a full custom design and manufacture service, with all healthcare water purification systems complying with the Medical Device Directive (MDD) 93/42/EEC, and being fully assessed and CE marked as Class IIB Medical Devices.

The consulting engineer’s guide to pure water

High quality water is critical for many applications in the healthcare sector, in particular in renal dialysis units, sterile services departments and laboratories.

Ensuring that water quality meets the appropriate standards and that water purification equipment is specified, designed and installed correctly requires specialised knowledge and expertise.


Renal water purification systems 

Our water purification systems for renal dialysis use tried and tested reverse osmosis, with options including chemical and heat sanitisation technologies. These systems are backed by our knowledge, skills and expertise, to help you optimise water treatment processes for standard and high flux haemodialysis, in both single patient and multi-patient applications.

We are also an approved Medical Device Manufacturer. Our standalone and ring-main water purification systems are approved to Medical Device Directive 93/42/EEC and are certified by the German Association for Technical Inspection (TÜV).


We offer a wide range of standard and custom built water purification systems decontamination and sterilisation applications. These include Centralised Sterile Services Departments (CSSD), Standard Services Departments (SSD), Hospital Sterile Services Departments (HSD) and AER (automated endoscope reprocessing) departments.

Our systems comply with all the latest HTM and ISO requirements, including (S)HTM2030, and are available with single and double pass reverse osmosis (RO) options, plus a range of up and downstream technologies and chemicals to provide the widest possible choice for public and private healthcare provision.

Endoscope Washer Feed

Our range of water purification systems for single or multi chamber endoscope washer disinfectors and steam sterilisation cabinets is fully compliant with (S)HTM 2030, NHS MES C32 and the latest draft prEN ISO 15883.

Each system is fully integrated, making setup and configuration quick and simple, with low maintenance and operating costs. Features typically include comprehensive data logging features, for full traceability, stainless steel bio-sampling points, automated chemical sanitisation and automatic monitoring of all critical functions.

Clinical Analyser Feed

Our range of advanced water purification systems ensure the highest quality feed for clinical analysers, being capable of producing water quality to 18.2MΩ-cm, with bacterial levels less than 1cfu/ml and the rejection of ions down to 0.01mg/l.

Every system complies with the latest clinical water quality standards, including ASTM, CLRW and CLSI and is available with a choice of control, monitoring and diagnostic options. Standard and custom engineered systems are both available, in each case providing a reliable solution that is easy to install and use, with low operating costs.

Central Deioniser feed

Our centralised water purification units use advanced reverse osmosis technology, in conjunction with activated Carbon and particulate filtration as part of the first stage of purification.

Water from the first stage is stored in an integral stainless steel tank providing a continuous feed to a ring-main. To maintain microbiological purity, the circulating water is continually purified using UV and membrane filtration technology. As standard, all systems are equipped with sophisticated integral data logging technology providing a historic traceability for key operating parameters.

Service, maintenance & support

To support our extensive range of healthcare and life sciences water purification we offer a full range of technical, applications and after-sales support services.

These include extended warranty and 24/7 service contracts, including routine servicing and replacement of consumables, plus emergency cover to ensure continuity of supply. This support is available either direct or through our global network of specially trained sales partners.

What our customers say:

Opting to work alongside SUEZ on our project was simple because they have a strong track record of delivering first-rate water purification solutions to hospitals and offered the best value for money compared with competitors.
Alex Best, Project Manager, Hull and East Yorkshire Hospitals NHS Trust
We are very impressed with the whole installation, which was completed on time and on budget. By working with an experienced solution provider such as SUEZ we now have a system that delivers everything we need to give our dialysis patients the very best treatment in our new Renal Unit. This equipment is vital to our main objective of protecting the health of our patients, while also ensuring reliable and efficient operation in the facility.
John Moore, Renal team leader for the Clinical Technology department, University Hospitals of North Midlands
SUEZ units consistently deliver the high purity and volume of water that we require. They’ve been problem-free since installation and thanks to the reverse osmosis unit alarm feature we are confident that in the event that a problem were to occur we would be alerted prior to the sterilisation process being affected, bringing us and our customers peace of mind.
Sandy Sayandan, Divisional Engineering Manager, IHSS- outsourced Sterilisation Services
SUEZ has worked closely with Mid Staffs hospital for more than 10 years, providing very good aftersales service and advice on matters relating to purified water. SUEZ was the Estate Department’s first choice provider and we are very pleased with the work completed.
