Cationic polyacrylamides have been employed widely to improve sludge dewatering performance, but the cationic units are randomly distributed in the molecular chain, which restricts the further enhancement of dewaterability. Common template technology to prepare block copolymers requiring a huge number of templates reduces the polymer purity and molecular weight. Here, we adopted the surface-act...

The purpose of this study was to quantify the occurrence and release of antibiotic resistant genes (ARGs) and antibiotic resistant bacteria (ARB) into the environment through the effluent and biosolids of different wastewater treatment utilities including an MBR (Membrane Biological Reactor) utility, conventional utilities (Activated Sludge, Oxidative Ditch and Rotatory Biological Contactors-RB...

Dewatering of water-coal slurry or thickened product under conditions operating SUEK-Kuzbass JSC enrichment plants is a promising direction obtaining technogenic mineral resources. It should also be noted that the quality obtained will directly influenced by initial raw materials. If content carbon particles high and average ash solid phase low, such interest in terms additional volumes coal af...

Dewatering involves reducing level of flooding field by various technical measure. This paper studies the methods dewatering involving measure water from surface quarries with help horizontal drilling. Horizontal drilling does not cause discomfort at exploitation works, transport and storage deposits being a very efficient method. has great advantage both in terms efficiency environment because...

The dewatering performance and fractal characteristics of alum sludge from a drinking-water treatment plant were investigated in this study. Variations in residual turbidity of supernatant, dry solid content (DS), specific resistance to filtration (SRF), floc size, fractal dimension, and zeta potential were analyzed. Sludge dewatering efficiency was evaluated by measuring both DS and SRF. Resul...

The agro-industrial sludge, tested in this work, comes from a biscuit factory (France). Initially, it contains 3 % w/w of dry matter. The actual treatment by centrifugation dewaters it to 13 % w/w of dry matter. Electroosmotic dewatering under pressure (EOD) was investigated, as an alternative technology of mechanical treatment, to improve dewatering. This electrical treatment efficiency depend...
