Cyanobacteria
Cyanobacterial monitoring uses fluorescence method at selected
wavelengths. Interpretation algorithms allow safe identification of
cyanobacteria.
Coli bacteria
Conventional methods for determining water pollution by e.coli or
coliform bacteria give results after 24-48 hours. Analyzers based on the
monitoring of specific enzymatic activity detect microbiological activity
within an hour and thus enable the timely implementation of the
necessary measures.
Dosing of coagulants and flocculants
The StreamingCurrent Monitor is used to optimize the dosing of
coagulants and flocculants to eliminate turbidity and organic pollution for
drinking water treating. The method uses the principle of particle charge
monitoring.
Filtration and settling
In this application, it is necessary to monitor the particles in the filtered
water. Coagulant dosing problems are dominated by fine particles,
which are measured with light scattering turbidimeters. However, in
order to control the filter rinsing and to monitor the settling technology, it
is necessary to monitor particles of micrometric dimensions which are
not detected by the turbidimeters. Optical particle counters are used for
this, with the possibility of categorization by size. Sizing is important to
identify technological problems.
Iron, aluminum, manganese + arsenic
Metals get to water from subsoil or may be the result of an overdose of
coagulants. Specialized colorimetric or coulometric analyzers with
suitable measuring ranges are designated for their monitoring.
Analysis of drinking water in pipes
The composition of drinking water in the distribution network may not be
uniform. It is ideal to monitor it directly in the pipeline. Due to the
limitations arising from the dimensions, the problem with the discharge
of the analyzed sample, or the power requirements, conventional
instruments are not suitable for this task. The ideal device for such
measurements is pipe::scan. Pipe::scan is a modular sensor system for
monitoring the quality of drinking water in pressurized pipes. This
compact instrument measures up to 10 parameters: TOC, DOC, UV254,
turbidity, color, chlorine, pH/redox, conductivity, temperature and
pressure.
Safety of drinking water systems
Compact spectrometric probes are an ideal tools for monitoring of water
composition, which can be supplemented with additional sensors to
monitor additional components such as pH, conductivity, soluble
oxygen, chlorine, chlorine dioxide and others.
However, due to unforeseen events, any toxic contaminants may enter
the water. They can be immediately identified by using of spectrometric
probes.
Water disinfection – by-products
An important step in the treatment of drinking water is its disinfection.
Analytical Instruments for monitoring chlorine, chlorine dioxide or ozone
are designed to monitor disinfection optimization.
Due to chemical reactions during the disinfection process, by-products
are formed which can also be harmful and need to be monitored. These
include trihalomethanes, which are suitable for continuous
measurement using a specialized analyzer.
Monitoring of flow in pipelines and identification of leaks
Accurate measurement of water flow in pipes using Flexim clamp-on
flowmeters allows balance determination of water leakage in critical
nodes and sections.
The attached flow meters enable fast and non-invasive realization of
measurements.
