During dialysis, a patient's blood is separated from more than 100 litres of dialysis fluid by only a thin membrane. Any germs, toxins or metals in that water can reach the patient. That is why dialysis water must be much cleaner than drinking water.
Why it costs so much
Many centres buy imported water systems. Spare parts are imported too, and repairs can take weeks. The real cost is not the price of the machine. It is the running cost, and the days the plant is down. When the water plant stops, patients are sent away.
Options made in India
- Dialysis water plant. Makes very pure water at 100 to 500 litres an hour, built to replace imported units.
- Pure water without acid and alkali. Removes the last traces of salt using an electric current, so no chemicals are needed to recharge it.
- Small pure water units. 25 to 60 litres an hour for labs.
What a good dialysis water system has
- Filters before the RO that suit your water: a softener, carbon to remove chlorine, and fine filters.
- RO, often two stages, to clean the water.
- Pipes that loop back with no dead ends, so germs cannot settle.
- Regular tests for purity, germs and toxins, with written records.
Testing is part of the system
A purity meter on the plant tells only part of the story. Regular lab tests for germs and toxins prove the water is safe. Plan the testing and the lab from day one.
Setting up or upgrading a dialysis unit?
We design the water system, and our NABL-accredited lab does the regular germ testing. See the options in our technology showcase.
Request a consultationFrequently asked questions
Is a normal RO plant enough for dialysis?
No. Dialysis water needs the right filters before the RO, often a second RO stage, pipes that can be cleaned, and regular germ testing.
What is electrodeionisation?
It is a final cleaning step. It uses an electric current and special membranes to remove the last traces of salt, without any chemicals.
How often should dialysis water be tested?
Purity is checked all the time by a meter. Germs and toxins are tested on a fixed schedule, often every month, as the standard and the doctor require.
