Flotation of sludge

Sens commun

Sludge separation process based on differences in hydrophobicity of the surfaces of the particles to be separated. E.g. Flotation of sludge is used in mineralurgy to separate minerals from each other and in the treatment of wastewater to remove fats.

Constructed wetland

Sens commun

System which allows the purification of wastewater by plants mostly reeds: the phytopurification. This method consists in making wastewater flowing through submersed plants, which roots have a high purification power.

Land application of sewage sludge

Sens technique

Action of spreading organic matter-laden wastewater over a surface, to treat it by percolation into the soil while feeding soils poor in organic matter.

Sludge thickening

Sens technique

Increasing the dry matter content of the sludge without modifying the liquid nature of the sludge. The thickening of sludge can be done merely by gravity in a concentrator or by mechanical means (dripping, flotation or centrifugation).

Water economy

Sens technique

A branch of the economy that theoretically deals with the relations between human societies and water, especially in economic policies relating to water, its consumption, use and pricing.

Rotating biological contactor

Sens technique

Biological treatment process at fixed culture on carriages. These rotating biological contactors (RBC), generally polystyrene, measure 2 to 3 m in diameter and rotate about a horizontal axis by being partly immersed. Sludges, putrescible very produced by this system are removed by a secondary clarifier.
