Hemodialysis is the process of filtering waste products from the blood of a patient whose kidneys are not functioning properly. This process involves the separation of the waste substances from the blood by allowing the waste time to diffuse through a semipermeable membrane. A special solution, called Dialysate, must be used during hemodialysis. This solution is comprised of ultra pure water with electrolytes and minerals to balance with the patient’s needs. Serv-A-Pure is a 510(k) FDA Registered Medical Device Manufacturer that has an excellent hemodialysis system to ensure your company receives the ultrapure water you need.

                                   Serv-A-Pure’s Complete Hemodialysis Water System

1. Break Tank:   First, the water is drawn into the break tank.   The water feeding the break tank flows through a cold-water fail-safe tempering valve.   Using a break tank eliminates the possibility of back flow into the municipal water system and insures an even pressure entering the pure water system.   2. Booster Pump:   After the break tank the water flows into a dual booster pump repressurization system.   The dual booster pumps ensure the water is at a high enough pressure for the pre-treatment to complete its job properly.

3. Pretreatment Equipment:   1.Carbon Tank #1 : This is the worker carbon tank that takes the majority of the chlorine and chloramines out of your feed water.   2. Carbon Tank #2: This is the polisher carbon tank that ensures the necessary amount of chlorines and chloramines have been removed for patient safety.   3. Water Softener: The water softener removes calcium and magnesium to increase the longevity of the RO membranes.   4. Centralized Test Station:   A centralized test station is a convenient way to obtain pure water sample at one central location.   Our test station is able to obtain samples from five different locations throughout the system. Centralized Test Station.

5. Single/Dual Pass RO System:

RO #1: After the water is pretreated
it is purified through a single RO.

Water exiting the storage tank enters a distribution pump. This pump enables the pure water to make its way through the loop and back.

RO #2: Sending the water through a second RO ensure the water meets any stringent water requirements you have.

DI Tanks: To ensure you water is pure enough, the water is then sent through deionization tanks. DI water can exceed 18.0 MegOhm*cm.

No need for DI backup cause either RO #1 or RO #2 can be used as a standalone system.

UV Light: Next, a UV light is used to kill all bacteria that remains in the water.

No need for UV light since RO #2 continuously feeds the loop fresh water.

Ultrafilters: UV lights kill the bacteria, but do not remove it from the water. Ultrafilters remove any remaining bacteria, dead or alive.

No need for ultrafilters since RO #2’s membranes more thoroughly remove bacteria and endotoxins than an ultrafilter.

Resistivity Meter: Measures the water purity to ensure it meets all necessary water standards for patient safety.

No need for resistivity meter since RO #2 has an integrated final conductivity meter.

6. Loop:

After the purifying is completed, the water is then sent out to the patients through a pure water distribution loop.

7. Wall Box:

Each individual station in our hemodialysis installations has their own wall box. Each wall box has a connection for pure water, drain, and an optional bicarbonate solution and up to 3 different acidified solutions.
