It is vital for dialysis machines to be operated with pure water, free from contaminants that will cause negative side affects to patients after receiving treatment. It is also crucial for the machines to be kept in the best possible condition, reducing the chance of fault due to build up of particles or contaminants within the system. Softening feed water before reverse osmosis will contribute to the reduction of metal ions that cause a build up of scale, furthered by RO to produce ~99% reduction of all other remaining ions and salts within the water.
Reverse osmosis will also remove ~99% of bacteria and viruses present within source water, contaminants that are obviously mandatory to be removed. Due to the delicacy of this application, further protective measures are used such as our premium carbon cartridges. These will specially target chloramines and heavy metals present in water that, when levels are too high, can overload and degrade the reverse osmosis membrane. UV sterilisation acts as another guard layer to ensure no microorganisms can grow within treated water.
Central plant dialysis machines require the recirculation of the purified water through systems multiple times, increasing the risk of endotoxin build up. Fine particle filtration is required to remove the broken down bacteria from pipework to ensure a final, pure product for cleaning.
