4Description
4.1 INTRODUCTION
The MICRO/2000® and DEOX/2000® Residual
Analyser utilises the same robust measure-
ment system with different set of chemical
reagents to cover the full range of analytical
measurements. The unit consists of a peristal-
tic pump, which delivers sample and reagents,
a measuring cell and probe. The system is
designed to continually measure the level of
free or total chlorine residual present in a
flow of water and, by control of the chlorine
dosage rate, maintain a predetermined chlo-
rine residual level in the treated water. The
MICRO/2000® and DEOX/2000® can also be
used to control levels of chlorine dioxide or
potassium permanganate in a flow of water.
In a MICRO/2000® configuration, the peristal-
tic pump ensures a consistent flow of sample
water to the cell where the residual is measu-
red. Where required for pH buffering and/or
total residual measurement, the pump also
delivers liquid reagents in fixed proportion to
the sample. Potassium iodide liquid reagent
must be added to the analyser sample for the
measurement of total chlorine residual and
acetate buffer to ensure that the sample pH is
maintained at pH 4. See Appendix A for further
information on the reagents. The system can
be used for residuals in potable water, primary
or secondary wastewater or cooling water
In a DEOX/2000® system it operates as a centre
zero analyser capable of measuring oxidants
(Chlorine and Ozone) and reductants (Sulphur
Dioxide). Potassium Iodide and Potassium
Iodate are mixed with Acetic acid to form
Iodine in a mixing coil. This is then injected
into the sample stream and subsequently
measured as a reduction current by the probe.
The presence of oxidant in the sample stream
causes excess Potassium Iodide to be oxidised
to Iodine resulting in an increase in the measu-
red reduction current, whilst the presence of
a reductant in the sample stream results in the
removal of Iodine and hence a reduction in the
measured current.
Simply, changes above or below the measured
Iodine baseline enable the unit to detect both
oxidants and reductants. See Appendix B for
further information on the reagents. The sys-
tem can be used for all dechlorination applica-
tions.
This manual has been produced to enable the
user to obtain maximum service from the
equipment and comprises installation, opera-
tion, maintenance and spare parts informa-
tion. Minor changes may be made to the
equipment that are not immediately reflected
in the manual - if such a change appears to
have been made, contact Evoqua Water Tech-
nologies for information. Our guarantee is
conditional upon the equipment being used in
accordance with the instructions herein and
we therefore recommend that they be read

5.4.4 Installing reagent hardware (See
Dwg. 50.505.020.010)
Before attaching the reagent bottle mounting
brackets to mounting surface, install the
retaining strap through the slots in the bra-
cket. The brackets should be located within
1.2m (4 feet) of the analyser.
• Install the reagent tubing as follows:
Uncoil the reagent tubing segment(s) (one
per liquid reagent) and remove the rigid
tubing segments (1/32-inch O.D., 330mm
long (13-inch long)) from the protective
packaging. Using two of the three tubing
segments, firmly insert one rigid tube into
one end of each piece of flexible tubing.
Then insert the exposed rigid end into the
small hole in the cap of each of the
reagent bottles mounted in the bottle
brackets. Route the tubing under the
facade and connect to the pump reagent
tubes.
• For information on installing or replacing
reagent tube units, refer to section 8.2.4,
"Pump tubing units replacement".
•TubingConnections:
Cut the excess reagent tubing and con-
nect to the reagent fittings at the inlet to
the reagent tube units.
Install the "T" fitting provided in the
tubing at the inlet to (bottom of) the ana-
lyser metering pump. To do this, cut the
tubing about 25mm from the entrance to
the pump and reconnect the tubing using
the "T" fitting. This will leave the middle
(small) end of the fitting unused.
• If two reagent tube units (two liquid rea-
gents) are used:
Install two, one-inch segments of the
reagent tubing, cut from the 2.4m (8 foot)
segment of reagent tube, on the fittings
at the discharge (upper) end of the
reagent tube units and join the two seg-
ments with the "Y" fitting provided.
Using approximately 175mm (7 inches) of
reagent tubing, connect the reagent
discharge fitting to the tee fitting at the
pump sample intake.
WARNING
To avoid possible severe personal injury or
equipment damage, do not service the
metering pump while power is applied to the
pump. The motor has enough torque to
cause severe pain and injury if fingers are
caught in the pumping mechanism.
WARNING
To avoid possible severe personal injury or
equipment damage, do not remove the
pump occlusion ring while there is any water
pressure at the inlet to the analyser. If the
pump occlusion ring is removed while pres-
sure is applied to the pump, water (possibly
containing acid reagents) can be sprayed
from the discharge side of the pump.
Sprayed water may result in damage to the
equipment or personal injury as it may con-
tain some reagent or may be contaminated.
NOTICE
It is recommended that water-flow to the
wetside should be blocked and the reagent
reservoirs are not filled until installation is
complete. The metering pump may be ope-
rated/tested without reagents or water wit-
hout damage; however, it is advisable to
pour enough water into the cell to cover the
impeller (mixer) before powering the unit to
prevent damage to the impeller shaft seal
caused by running the unit dry.

5.4.5 Connecting the sample water
MICRO/2000® and DEOX/2000® water sample
and sample line requirements:
Actual requirements will vary with the equip-
ment application, but the following should be
used as general guidelines. Sample plumbing
design is the most important part of a reliable
monitoring system.
A well-designed sampling system minimizes
response time, prevents fouling of the sample
line plumbing and the analyser, and provides a
fully developed turbulent flow to the analyser.
Response time is minimized by locating the
analyser close to the point of sample take-off
and by designing for a moderately high flow
velocity in the sample line, 1.5 m/s (5 ft/sec).
Flow velocity also helps in reducing sample
line deposits.
Plastic pipe or tubing (PVC, ABS, or polyethy-
lene) is preferred for sample line plumbing
due to its corrosion resistance, lack of residual
demand, and smooth surface finish, which
resists deposits. Never use copper pipe or
tubing. Avoid the use of metal lines or fittings.
Sample plumbing pipe (or tubing) size is a
function of the available pressure at the sam-
ple point (or sample pump discharge) along
with the sample line length and flow velocity
required.
5.4.5.1 Potable Water
Four characteristics typical of potable water
are that, generally, it is low in particulates, it is
available at reasonably high pressure >1 bar
(>15 psi), its use should be minimized, and the
wetside may be mounted within 7.5m (25
feet) of the sample point. In such applications,
the sample may be run through 6mm (¼-inch)
pipe or tubing and the bypass flow on the Y-
strainer may be shut. It should be opened only
intermittently to flush the strainer element
and sample line. Then only approximately 500
ml/min of the sample is required, which is the
internal analyser sample requirement.
5.4.5.2 Wastewater
Frequently, wastewater is high in particulates
and biological growth potential. The sample is
taken from open channel flow, with no pres-
sure available at the sample point. Additio-
nally, the wetside must frequently be
mounted a significant distance from the sam-
ple point (inside and protected from weat-
her). Here, a sample pump is required and the
Y-strainer bypass flow valve should be open to
allow continuous flushing of the strainer ele-
ment. A high flow, low pressure, open impel-
ler type pump works well in this environment.
Typical systems use ½-inch pipe or tubing that
bypasses 7.6l/m (2 US gpm) through the Y-
strainer or 3/4-inch pipe that bypasses 19l/m
(5 US gpm). This results in a flow velocity of
about 1.2m/s (4 feet/s) and a pressure drop of
about 0.3 bar (4 psi) per 30m (100 ft) of sam-
ple line.

Wastewater will frequently exhibit high biolo-
gical growth potential; therefore, the sample
line may need to be treated with a cleaning
(biocidal) agent (typically chlorine) to inhibit
growth in the sample line. Biological growth
may clog fittings in the sample line or wetside
and consume (process) chlorine residual
during the sample transit time in the sample
line. For sample line dosing, the cleaning
agent is periodically injected into the sample
line near the sample intake point.
A self-flushing, 1/2-inch Y-strainer is provided
and should be located at the analyser. Valves
are provided to be installed on the Y-strainer
bypass discharge to control bypass flow and at
the filtered discharge from the Y-strainer to
the 1/4-inch sample inlet at the base of the
flow block.
The analyser enclosure is equipped with a
hose adapter drain connection for 1-1/4-inch
hose.
1 Slip 1-1/4 inch drain hose over the end of
the drain fitting and run hose to a waste
drain.
2 Connect a hose from the Y-strainer bypass
valve to the waste drain.
3 Inside the wetside, insert the analyser
bypass tubing and cell discharge tubing
(both 1/4-inch OD translucent) into the
drain fitting.
