30/05/2017 This video depict a mechanical wastewater sludge thickening. It is possible to observe the high solids concentration in the sludge thickened and the quality ...
The thickeners must be preceded by flow balancing tanks to contain and mix intermittent sludge discharges and feed the thickeners at a consistent concentration and uniform rate (Fig. 13.1). In applications where used washwater (without settlement) is mixed with clarifier sludge, the sizing of the flow balancing tanks becomes critical because of the large surges of dilute used washwater. The ...
For rapid mixing, hydraulic or mechanical rapid mix with a mixing energy of G=300 to 500 s −1 should be used. ... The settling velocity in thickening sludge often shows an almost exclusive dependency on the local solids concentration so that the equation G i =c i v i can be considered a unique function for a given sludge, applicable at any location in the thickener. At all locations in a ...

Sludge stabilisation - Home An overview of sludge stabilisation − alkaline stabilisation, lime and solids dosing, plus anaerobic and aerobic digestion ; About sludge stabilisation Stabilisation processes reduce the odour and putrescence of sludge, and level of pathogenic organisms ; Alkaline stabilisation Alkaline stabilisation is a chemical method to reduce sludge odour and putrescence, and ...
Gravity belt thickener – GBT The OMEGA Gravity Belt Thickener is designed for the continuous mechanical thickening of municipal or industrial sludge. This simple and efficient technology aims at reducing the sludge volume at least 6 to 7 times according to sludge characteristics. Low energy consumption, Construction stainless steel as as ...
The mechanical sludge collector and thickener comprises an eductor pipe assembly 36, a wiper arm assembly 38, and a drive assembly 40 which cooperate to aid the flocculation process, scrape the sidewalls of the tank and remove the sludge from the tank. The eductor pipe 36 is provided at its lower end with a base plate 42 that is interconnected to the lower end of the eductor pipe 44 by means ...

They generally produce a still pumpable, but much thickened sludge. Gravity Thickeners. They employ the natural tendency of higher-density solids to settle out of liquid to concentrate them, combined with mechanical assistance to augment the process. Think of the example in a kitchen of passing a stock through a sieve, using a spoon to stir and agitate the process to encourage more liquid to ...

With regard to the economical further treatment and disposal of sewage sludge, it is necessary to reduce the sludge volumes produced within the course of the wastewater treatment process. This volume reduction is achieved by the separation of parts of the sludge liquor at different points within the sludge treatment process chain. The main field of application for thickening systems is volume ...
