Furthermore, the effect of initial guesses to the optimization results is considered. The simulations are executed in Matlab ® and fmincon is used as optimization algorithm with some improvements. Index Terms — activated sludge, ASM3, design, optimization.

A Specious Correlation between Sludge Rheology and

To achieve good dewaterability, the conditioning process should create sludge flocs providing a porous cake during compression but also a high resistance to erosional stresses. This suggests that sludge''s rheol. characteristics, some of which (like the yield stress or the storage modulus) represent its network strength, should be related to the material''s dewatering properties.

Roles of iron species and pH optimization on sewage

Conditioning sewage sludge with Fenton''s reagent could effectively improve its dewaterability. However, drawbacks of conditioning with Fenton''s reagent are requirement of acidic conditions to prevent iron precipitation and subsequent neutralization with alkaline additive to

Optimization study on sewage sludge conditioning

Sludge conditioned with chemical polymer often termed as undesirable use for land appliion. However, using natural polymer will help to reduce the impact of this problem. In this study, optimization using Moringa oleifera seeds as a natural polymer in sewage sludge conditioning is highlighted.

Sludge conditioning, thickening and dewatering

7/12/2020· Mechanical dewatering processes are commonly used to reduce the sludge volume; aiming at the optimization of energetic or agricultural recovery of the sludge, storage and transport. Dewatering by screw centrifuge is one of the most important and widely used operation in sludge treatment.

Conditioning effect of lysozyme coined with freeze

Additionally, the bound water content of sludge decreased by 47.5% after co-conditioning, consistent with the enhancement in sludge dewaterability. All the results showed that LZM in coination with freeze-thaw conditioning had a great potential in sludge reduction, providing more opportunity of resource utilization for the dewatered sludge.
