15 minutes - Answers length of time RO has to be running B4 water samples can be taken for RO water
sample and chlorine testing
AAMI - Answers association for the advancement of medical instrumentation, develops voluntary
standards for dialysis
action level - Answers level at which we must take corrective measures.
adsorption - Answers means to attract and hold on a surface. the binding of chlorine and chloramine
molecules to the granulated activated charcoal
alternative water supply plan - Answers approved by the medical director, provides instructions if city
water is interrupted, insures facility meets AAMI standards even if one or more components of the
locations system fail, posted in water treatment area
backflow prevention device - Answers to keep water from flowing backwards into incoming water
supply, installed at start of system
backwashing - Answers means forcing water backwards thru a filter, removes particles clogging filter
bicarbonate - Answers a buffer, neutralizes acids that form when the body breaks down proteins
bicarbonate mixer - Answers used to mix bicarbonate concentrate solutions for jugs
booster pump - Answers Boosts feed water pressure
breakthrough - Answers test results after the first carbon filter that are at or above the action level of
0.10 ppm
brine tank - Answers Holds salt pellets mixed with water for the softener
carbon tank - Answers contains granular activated carbon which absorbs low molecular weight particles
from water, chlorine, chloramines, pesticides, industrial solvents and trace organic substances
chemical feed system - Answers used to lower feed water pH in RO systems, acid injection corrects
alkalinity or pH >8.0.
chlorine and chloramines - Answers are harmful to patients, causing hemolysis, together chlorine and
chloramines form total chlorine
colony forming units - Answers a measure of the number of living bacteria
conductivity - Answers ability of a fluid to transfer electrical charge
, deionization tank - Answers DI is emergency backup for RO, rarely used as primary treatment, uses beds
of resin beads to remove ions, these are exchanged for hydrogen and hydroxide ions to form water
delta pressure - Answers Pressure difference pre and post filter, limit 10psi
direct feed - Answers water system design in a facility that does not have a holding tank
empty bed contact time (EBCT) - Answers period during which feed water must remain in contact with
the charcoal bed in a carbon tank, AAMI standard is 10 minutes total EBCT, fmc 12 minutes

water supply, due to break in main, flooding or bacterial contamination. GAC testing increased to hourly
HMIS - Answers hazardous materials identification system, this permanent labeling required on SDS
equipment uses colored bars, numbers and symbols to alert staff to chemical hazards
hydrometer - Answers used to measure specific gravity of an acid concentrate after mixing, must be +/-
2% of expected range
IFU - Answers instructions for use
indirect feed - Answers water system design in a facility that has a holding tank
initial volume - Answers the quantity of treated water in the mix tank prior to adding bicarbonate
concentrate powder
ion exchange - Answers the process that occurs inside a deionizer for water treatment. unwanted ions
are exchanged for hydrogen and hydroxyl ions to create pure water
