Dialysis RO system
An RO water system for haemodialysis is a specialist engineering system: water quality, treatment configuration, wetted materials, storage and distribution, and operating control are reviewed together against the specialist requirements and the facility's actual conditions.
Treatment & distribution
A dialysis RO system is reviewed along the whole water path. Each segment has its own function but must match the others in capacity, hydraulics, materials, controls and operating conditions.
01
Source water
Source water data is the basis for pre-treatment, configuration and the treatment level required.
Source water data
The specific configuration, number of RO passes, storage, circulation and disinfection are set by each project's technical requirements, applicable standards and actual conditions; no single configuration is assumed for every facility.
More than pure water
In haemodialysis, water quality must hold across the whole system, from treatment to the point of use, not only at the RO outlet.
Water quality
Physico-chemical, microbial and related parameters are controlled to the applicable limits and regulations.
Whole-system configuration
Source water, pre-treatment, RO, storage, distribution and points of use belong to one technical configuration.
Wetted materials
Materials, piping, tanks and wetted parts must suit the system's function and requirements.
Sustained quality
A single test result is not enough; the system must help keep water within limits during operation.
Operation & disinfection
Circulation, cleaning/disinfection, monitoring and maintenance are considered from the design stage.
RO water for haemodialysis
For water systems serving haemodialysis. General and technical RO belong to the clean water treatment solution.
Segments integrated as one
Pre-treatment
Stages before RO are set by the source water quality and the protection the downstream system needs.
RO unit
Membranes, pumps, housings, piping, instrumentation and related parts are configured to the system requirements.
Tanks & storage
Reviewed together with material, volume, cleaning/disinfection and operating requirements.
Distribution loop
Piping, circulation pumps, hydraulics, materials and points of use are arranged to keep the distribution network in condition.
Disinfection
The disinfection method follows the system's configuration, materials and operating requirements.
Instrumentation & control
Monitoring of required parameters, equipment status, alarms, interlocks and protection.
04
Each segment is calculated for its own function and checked against the others.
01Capacity & flow
Define demand, usage pattern, design flow and the flow relations between segments.
02Pressure & hydraulics
Calculate pressure, losses, pump head, pipe sizes and circulation conditions.
03Equipment & materials
Selected by function, duty, water quality requirement and cleaning/disinfection method.
04Layout & maintainability
Space, equipment access, operation, consumable replacement and maintenance.
05Operating reliability
Interlocks, protection, redundancy and the conditions needed to limit interruptions, as the project requires.
06Technical documents
Configuration, parameters, diagrams, instructions and operating documents set out within scope.
