DRINKING WATER

The quality of drinking water is measured at different stages: at the entry to the treatment plant, during the treatment process, at its exit from the treatment plant and all along the distribution network.

 

SURFACE WATER

Whether in the form of monitoring stations or mobile laboratories (fixed or mobile stations), SERES environnement plays a role in the protection of surface water, spring water, rivers and groundwater. The aim is to obtain real-time measures of surface water pollution, in order to, if necessary, protect drinking water at its source.

 

WASTE WATER

Automatic analysis of waste water requires a great knowledge of effluents. For over 40 years now, SERES environnement has developed various systems of on-line sample preparation, such as paper filtration, tangential filtration or sample intake through sampling loops.

 

PROCESS WATER

The automatic analyser is the only one which fulfils the requirements of real-time measurements, suited to industrial processes. The monitoring of process water quality, such as cooling water, is standard. However, each industrial process has its own particularities.

 

SEA WATER

Prevention of the pollution of sea water by hydrocarbon wastes:

• Oil tankers,
• Oil Rigs,
• Refinery wastes.

Parameters measured:

Aluminium, Ammonium, Total nitrogen, Total phosphorus, Bromine, Free Chlorine, Chlorides, Chromium, Colour, Copper, Cyanides, Iron, Fluoride, Manganese, Morpholine, Nickel, Nitrites, Phenols, Phosphates, Silica, Sulphates, Sulphites, Total alkalinity, Total Hardness, TA / TAC, Zinc.

Several methods of analysis:

• Colorimetry
• Titrimetry
• UV, IR Spectrometry
• Potentiometry
• Nephelometry

Analyser characteristics:

• On-line measures : automatic or continuous
