Raw Water

In every industry it is important to determine the substances contained in the raw water being used. If the balance is wrong, plant components could be damaged — or even the entire line could grind to a halt.

Raw water is the name given to untreated water, consisting mainly of groundwater and surface water. Once it has undergone appropriate treatment, it is used for industrial purposes or as drinking water.

Before raw water can be used in this way, it has to go through special treatment and purification stages. These processes can be fine-tuned by continuously monitoring the quality of the raw water used. These analyses can be carried out either directly as part of the treatment process (online) or in the laboratory using samples.

The parameters most frequently analysed are:

• Nitrogen compounds such as ammonium, nitrates and nitrites
• Conductivity
• Oxygen
• pH
• Iron
• Manganese
• Chlorides
• Sulphates
• Phosphates
• Hardness
• TOC
• COD
• Silica
