Définition
Sens technique
Are mainly derived from the decomposition of plants, animals and micro-organisms. Their composition is therefore very diverse. They have a great impact on water quality parameters: colour, odour, disinfection by-products, taste, etc.
Are the cause of the degradation of water quality, thus :
- They influence the organoleptic properties of the water (odour and taste);
- They can be the cause of a certain toxicity acquired during treatment, through the metabolisation of certain compounds, such as the formation of THMs induced by oxidation, more particularly by chlorination;
- They directly influence the biological stability of the water in the distribution system.
