Due to the negative charge on the surface of sewage sludge particles, cationic PAM frequently achieves a more favorable conditioning effect. ... Furthermore, there are some novel dewatering techniques for sludge, such as vacuum preloading and electroosmosis dewatering. The next sections discuss typical dewatering methods and …
The aim of this paper was to contribute to the study of sewage sludge management issue in Morocco by identifying the various constraints hampering the sustainable disposal and/or recovery of ...
In this paper, nutrient recovery from sewage sludge as struvite using pulsed electric field (PEF) technique was performed. Box-Behnken response surface methodology (BBD) was used to determine the best struvite formation conditions. NH4-N removal efficiency (Y1) and PO4-P removal efficiency (Y2) were considered response functions, …
A comparative study to the performances of the drying bed and the draining greenhouse was made in summer and winter. During each season, the first experience was conducted in the drying bed. The two other experiences were carried out in the draining greenhouse under natural and forced convection. The results show that in terms of …
