Water Treatment & Dialysate – Questions/Answers
90 Correct Ans - Water makes up _____% of dialysate
Water, Acid, Bicarbonate (buffer) Correct Ans - Dialysate is made up
of
Pre-treatment, Water purification, Distribution Correct Ans - What
are the 3 processes that make up the water treatment system for
hemodialysis?
Backflow Preventer Device Correct Ans - Prevents pre-treated water
and disinfectants from backing up into the city water supplies.
Temperature Blending Valve Correct Ans - Mixes hot and cold water
to allow the Reverse Osmosis equipment to function at the most efficient
temperature which is 77 degrees F.
Booster pump Correct Ans - Increases incoming water flow and
pressure, maintains water pressure needed for components operation and
eliminates wide pressure fluctuations.
Multimedia Filter (Depth) Correct Ans - Filters out suspended
particles like silt and sand in water and traps solutes and other substances.
Water Softener Correct Ans - Softens hard water by removing
calcium and magnesium from incoming water. The water softener and
brine tank (salt) work together to prevent hard mineral deposits (scale)
from accumulating and potentially damaging the RO membranes.
Carbon tanks Correct Ans - Essential for removing
chlorine/chloramines from the city water.
2 (primary and secondary) Correct Ans - How many carbon tanks
are in the pre-treatment water system?
Reverse Osmosis Correct Ans - A way to remove solutes from a
solution using a membrane and pressure
, Deionization Correct Ans - Removes anions and cations from water.
(Does not remove non-charged particles)
anions Correct Ans - Negatively charged ions
cations Correct Ans - Positively charged ions
resin beads Correct Ans - What attracts cations and ions and
exchanges them for other ions in the deionization tank?
low Correct Ans - If water is acidic then it has a ____pH?
Alkaline Correct Ans - If the water has a high pH then it is?
product flow, waste flow, direct systems Correct Ans - What are the
3 flow meters in RO devices?
Product flow Correct Ans - This meter tells you how much purified
water is getting through the membrane.
Waste flow Correct Ans - This gauge tells you how much reject water
is being flushed down the drain
Direct systems Correct Ans - This gauge tells you how much product
water is recirculated through the system to blend with the incoming water.
total dissolved solids Correct Ans - What does TDM stand for?
parts per million Correct Ans - What does ppm stand for?
sepsis Correct Ans - blood poisoning
Chloramines Correct Ans - Made by mixing chlorine and ammonia.
They are used by cities when a long acting chlorine is needed.
Methemoglobinemia Correct Ans - If patients are exposed to high
levels of chloramines, or nitrates; red blood cells many not be able to can't
carry oxygen which is known as...
