SLUDGE Tchickening

 
The thickening is the first step, often unavoidable, reduced volume of sludge removed from the water system. It optimizes the steps of conditioning, stabilization and dehydration by reducing the sizes of structures and operating costs. Processes used are the gravitational settling thickening (thickening static) and dynamic thickening (concentration implementing dynamic energies).
 

Sludge dewatering

 
The sludge resistance to filtration and compressibility factor too high to ensure an optimal separation of water and matter. Therefore, one must first "break" the cohesion of colloidal mud and artificially increasing the particle size. This is the purpose of conditioning is the basis of satisfactory operation of the dehydration plant, to achieve the objectives in terms of final dryness, performance and operating costs through such techniques as dewatering by pre-liming before centrifugation by Dehydris Lime.
