Disinfect Alarm Monitor (DAM)
The Disinfect Alarm Monitor reduces the possibility of patient and equipment exposure
to disinfectants. The monitor provides a dependence requiring that Disinfect key
switches, located on the RO Controller and RO Status Monitor, are purposely engaged
prior to introducing disinfectants or cleaning agents into the loop piping. The key switch
dependency ensures that disinfect operations are an intentional and deliberate act.
A disinfect alarm timer controls the duration of the immutable audible disinfect alarm
and prevents RO use for a preset duration (set for 10 minutes upon shipment).
Softener
A water softener system removes calcium, magnesium, and other scale producing
contaminants from the feed water. It is an ion exchange device that substitutes sodium
for larger and more highly charged cations in the feed stream. Their removal reduces the
buildup of scale on the membrane surface. The control valve will initiate the
regeneration of the device and will extract the hardness ions with a brine solution and
rinse the ion exchange bed afterwards. The control valve is normally governed by a time
clock; alternate controls are available from the factory. Scale control by chemical
treatment is also available.
Storage Tank
A storage tank is used to collect RO product water and store it until needed. The reservoir
system has internal features that, with the distribution pump running, continuously wash
the sidewalls and top. Reservoir systems are available with level controls and low-level
alarm monitoring.
Distribution Pumps
Distribution pumps are used to pressurize the RO water for delivery to the point of use.
The pumps, available in both single and multi-staged centrifugals, run continuously to
prevent stagnation of the system. The moving water prevents planktonic microorganisms
from colonizing and results in increased efficiency of disinfection efforts.
Earthquake/Shock Restraints
Shock restraints are available for locations where they may be required by local codes.
Ultraviolet Sterilizers
UV sterilizers are used to kill planktonic (free floating) microorganisms without adding
chemicals to the water. UV Bulbs produce germicidal rays that are 99% efficient at
inactivating microorganisms.
