1998-3-1  Biological sludge during long time storage or expression decomposes. Testing of original sludge is accomplished within 2 (transportation) h+2 to 4 (expression test) h, a far shorter time period than that spent in Kawasaki et al., 1990, Kawasaki et al., 1994 (up to 44 h) and is one that has apparently negligible effects on sludge characteristics.

Anaerobic Digestion and Dewatering of Biological Trickling ...

This study investigated digestibility of biological trickling filter (BTF) sludge (in terms of the mass and volume reduction of the sludge) and the effect of anaerobic digestion on sludge dewatering. Nine 20-L anaerobic digesters fed with BTF sludge were set up in a dark constant-temperature room at 20°C and operated for 6 months.

Sludge, Sludge Dewatering, Why How To Dewater

Sludge is the sediment, particle and floating object produced in the treatment of wastewater by physical, chemical, physical-chemical and biological methods. Sludge generally refers to the semi-solid slurry between liquid and solid, which can be transported by slurry pump, but it is difficult to separate solid and liquid through sedimentation.

Sludge dewatering for solid-liquid separation KUGLER

Dewatering of the fresh sludge counteracts the concentration of the ammonium nitrogen (NH 4 -N) contained in the sludges, which otherwise becomes often a burden on “biology”. For continuous sludge pressing, screw presses are ideal. The smaller screw press models from KUGLER, for example, a ready-to-use container solution (no building ...

2011-6-7  The objective of this work was to evaluate the performance of biological industrial sludge dewatering by a pilot-scale filter press assisted by electrokinetics (EK). In all experiments the following conditions were kept constant: (1) dry solids content in the sludge feed: 5.0 wt%; and (2) constant electric-current mode.

Sludge treatment Complete Solution for Sludge Treatment ...

Sludge treatment is an important part of the wastewater treatment process, including both biological and chemical wastewater treatment plants.The first step is often a thickening process, where the solid content of the sludge needs to be increased, either for further processing of the sludge in a digester, or simply to condition the sludge, before feeding it to the dewatering equipment.

Gel Dewatering Process for Biological Slurry SpringerLink

Biological slurries, such as excess activated sludge from wastewater treatment plants, organic waste slurry from alcohol production process, etc., generally contain tremendous amount of water. Most of these slurries have to be concentrated/dewatered before further processing so as to make the relevant process economically feasible.

Generally, the moisture content of waste sludge in the wastewater treatment plants is above 80%. The characteristics of high moisture content have led to high transportation and treatment costs. Therefore, enhancing sludge dewatering by ZVI is an ideal strategy for reducing these burdens and promoting sludge treatment efficiency.
