Pyrolysis model of olive mill waste water sludge is developed in Aspen Plus based upon the experimental results. Pyrolysis of olive mill waste water takes place at 450°C in a fluidized bed reactor. The products are passed through cyclone at 350^°C for removal of biochar. Bio oil vapors and non-condensable gases are passed through a series of ...
The anaerobic digestion of wastewater treatment sludge (WAS) produces a "green" biogas while reducing the amount of residual sludge. To increase the yield of biogas, several individual or combined pre-treatment methods of WAS can be used. These pre-treatment methods substantially reduce the amount of volatile suspended solids …

The stirred ball mill (SBM) method is a common method applied in large-scale sludge disintegration. Many reports focus on the disintegration results of sludge or the inuence of parameters on the anaerobic process of treated sludge, but there have been few studies on the mechanism of sludge disintegration by SBM.
Limestone is typically pulverized in a wet ball mill, and the erosion and corrosion of the balls contribute iron to the limestone slurry. ... Primary clarifiers for FGD wastewater treatment are ...
The effects of ball mill pretreatment and Mn catalytic ozonation on the reduction of sewage sludge were investigated. The ball mill pretreatment increased ΔSCOD from 2,000mg/L to 9,000 mg/L, as Total Solids (TS) increased from 1% to 4% at a specific energy of 75.8 KJ/g-TSS. The increase in disintegration ratio (DR), which is an …
Ball mill-increases the sludge specific surface area ... Several research studies have been conducted on utilizing TPAD to predigest SS. A recent study performed TPAD on wastewater sludge digestion and found a 77% reduction in VS along with a methane release rate of 3.55 ± 0.47 L CH 4 /L day at 45 °C [159].
In this paper an overview is given for sludge minimization (sludge mass reduction) options. It is demonstrated that sludge minimization may be a result of reduced production of …
In order to enhance the biodegradability of the excess sludge generated from the wastewater treatment, a centrifugal vibration mill was used to mill the activated sludge. The centrifugal vibration ...
Pulp and paper mill sludge is an organic residual generated from wastewater treatments (Faubert et al. 2016). Per unit of paper production 23.4% sludge is generated. The major components of the paper mill sludge are inorganic residues and organic cellulosic fines and fragments (Albuquerque et al. 2015; Abdullah et al. 2015). …
The research presented an overview on sludge types, characteristics and methods of treatment. Additionally, using the sludge as an energy sources for future plans was studied as well.
The nanocomposite was used as a reagent to degrade persistent organic pollutants in the sludge of a petrochemical wastewater treatment plant by a planetary …
