Continuous Analysis. Reliable Results.
COMPOSER Joseph Lanner - Online-Analyser for Iron and Manganese
Basic Information
This Instrument was developed and built
for Drinking Water Industry.
Drinking water. Iron may be present in
drinking-water as a result of the use of
iron coagulants or the corrosion of steel
and cast iron pipes during water
distribution.
There
is
usually
no
noticeable taste at iron concentrations
below 0.3 mg/litre, and concentrations of
1–3 mg/litre can be acceptable for
people drinking anaerobic well water.
Manganese is naturally occurring in
many surface water and groundwater
sources, particularly in anaerobic or low
oxidation
conditions.
A
provisional
health-based guideline value of 0.5
mg/litre should be adequate to protect
public health.
Toxicity. Iron is an essential element in
human nutrition. Portable water shoud
contain iron not more than 0.2 mg/L.
Ground water may contain iron at
concentrations of several miligrams per
litre.

metal
complex is directly proportional to metal
concentration.

Advantage of the system
Non toxic chemistry.
Robust design.
Minimal maintenance.
Easy handling.
High accuracy and precision.
Suitable for mission critical
applications.
Automated cleaning and
calibration.

Method
Metal is measured as chelate complex
between metal ions in the waste water
and
sensitive
spectrophotometric
reagent dye. Change of the intensity of
the visible light throughout measurement
