Water treatment technology is aimed at neutralisation, disposal or recycling. Therefore, the choice of treatment technology and equipment depends primarily on the properties of water and the requirements of maximum allowable concentration.
Not only toxic substances can act as pollutants. Pollutants can also be oils, surfactants, heavy metals, the acidity of the environment, total hardness (above normal) and the content of ammonia nitrogen, oxidation, etc.
|Pollution type||Purification type|
|Suspended solids with particle size of more than 0.01 mm||
|Suspended solids with particle size of more than 0.5 mm||
Primary settling without chemical reagents
|Organic substance immiscible with water||
|Colloid particles with the size from 0,1 to 10 micron||Microfiltration|
|pH, total basicity, total acidity||Neutralisation|
|Water with oil concentration of more than 10 mg/l||
