Introduction
The untreated water is pumped through the carbon-based,
Pre-treatment Module
(
TC001
) to trap larger
particles that are greater than 20 micron, as well as chemicals such as insecticides, pesticides, herbicides,
and chlorides. The pre-treatment module is essential to protecting the RO membranes and must be
replaced at the stated intervals to retain the integrity of the RO membranes as effectively and efficiently as
possible.
The water then passes through one or more
RO membranes
(
TC006/TC013/TC026
). The RO mem-
brane rejects almost all bacteria, viruses, heavy metal compounds and organics, as well as removing 98 per-
cent of the salt content from the water. A percentage of the rejected water, referred to as the
concentrate
, is
sent to the drain through a
Flow Restrictor
(
R1
), while the remaining water re-enters the system to pass
through the RO membrane again, conserving water.
The product water, referred to as permeate, is measured through the
Permeate Conductivity
Sensor
(
Q2
) as it leaves the membrane. When the water quality measure is within the set limits, the
Per-
meate Solenoid Valve
(
V4
) is opened and the permeate water is fed into a
Storage Tank
(
TANK
) where
it is held as Type 3 water. As another option, the water can be dispensed to a distribution system or other
equipment using Type 3 water.
Should the water quality measure outside of the set limits, the system will display a warning for the user to
recycle or flush the water to drain.
