Plant - Water Treatment
The Plant - Water Treatment is a lockable room for water treatment systems, including particle filters, water softeners, carbon filters and reverse osmosis (RO) water plant/systems, for the provision of safe water for patients receiving haemodialysis therapy.
The Water Treatment Plant Room should be located in close
proximity to the Renal Dialysis Unit to permit short tubing runs to each Treatment Bay, and permit staff to
monitor and service the water treatment systems.
Refer to manufacturer's specifications for details of RO water treatment plant equipment. In particular, this
equipment will incorporate a heat disinfection function, and water saving features. The final components of
the system will be determined by the quality of feed water and the ability of the overall system to produce
and maintain appropriate water quality. Water treatment requirements to be confirmed by a dialysis water
Special Design Requirements:
- High level sound isolation is required to ensure noise generated from this room does not invade treatment spaces.
- Structural engineer's assessment must be sought for floor load bearing capacity with respect to water treatment and pre-treatment plant equipment.
- Ventilation, exhaust and/or air-conditioning must be designed to accommodate the heat loads of the specified equipment.
- Light is to be minimised; there are to be no windows provided.
- Service access will be required around the perimeter of plant equipment, clearances will be determined by manufacturer's specifications.
- A second door may be provided for separate deliveries and maintenance access if located in the patient treatment area.
- Pipework and components installed after the water inlet in this room shall not contain brass or copper.
- Options for cooling of high temperature (circa 90°C) waste water discharged from RO plant is to be considered.
- Where chilled water is not available, a chiller may be required outside the plant room. The maximum temperature of the feed water to be assessed to allow determination of any requirement for a heat exchanger or chiller design as determined by expert. The intent of this is ensure the temperature at the dialysis point for patient care is between 30-37°C.
- Redundancy within the pre-treatment and treatment devices/filters should be considered based on the hospitals service criticality level, the feed water quality or risk around quality, and the hospital location where supply of replacement equipment is difficult.
