Various sludge disintegration technologies for sludge minimization are discussed, including mechanical methods (focusing on stirred ballmill, highpressure homogenizer, ultrasonic disintegrator), chemical methods (focusing on the use of ozone), physical methods (focusing on thermal and thermal/chemical hydrolysis) and biological methods ...
Coalwater slurry fuel was made in a ball mill which pulverised the coal or coal sludge. This was done near a coal mine in Belovo, Siberia. The coalwater slurry fuel was transported through a pipeline to Novosibirskaya TEC5, Novosibirsk, a distance of 262 km (163 mi). The pipeline had three intermediate pumping stations.
sludge disintegration were examined. Best results were achieved while using the stirred ball mill or the high pressure homogenizer (500 x 105 Pa). An average energy consumption for these methods was: 0,224 kWh/kg of dry solids and 0,28 kWh/kg of dry solids, for ball mill and homogenizer respectively.

May 02, 2000· The concentrated effluent/sludge at the bottom of the cone bottom tank 12 is introduced by line 13 into a ball mill 15. Ball mill 15 has the proper charge of balls both in number and size and grinds the sludge for the proper time to achieve the resolution of the emulsion and achieve simultaneous particle size reduction.
It also investigates the geotechnical properties of seven paper mill sludges for, plant sludge from a recycling paper mill Sludge E is a primary wastewater treatment. Papermill industrial waste as a sustainable source for,
The paper sludge ash powder was used as a raw material. Planetary ball mill was used for mechanical treatment of solids. Each milling was carried out with a 100g sample in a 500ml capacity zirconia pots containing zirconia balls of 10mm diameter. The mill was rotated at constant revolution speed at 300rpm. The raw material
Sludge Treatment. The sludge treatment stations include all fluid handling including the addition of primary thickeners‚ final addition of thickeners (such as Iron Chloride)‚ addition of Calcium Hydroxide‚ processing of digested sludge and removal of filter cake.
Dewatering, pressing and drying sludge with filter belts . GKD filter belts made of synthetic fabric offer the ideal solution for the dewatering and drying of every type of sludge. array(0) { } In collaboration with renowned manufacturers of belt presses, thickeners and belt dryers we have developed tailormade synthetic fabrics for municipal and industrial sludge.

Ceramsite firing mechanism: At high temperatures, the pellets melt, producing a suitable viscosity and surface tension, while a chemical reaction occurs internally to release the gas, which acts on the molten liquid phase to cause pores to swell.
Sludge Extraction. The waste generated from tank or lagoon cleaning is often a dense sludge with a high percentage of solids suspended in a water and oil mix. This can make removing the sludge problematic and if the correct method is not selected or the equipment is not suitable a .
Subsequently, an effective use of Zr and Ti in the wastewater generated after the ballmill treatment was attempted. Crystalline αZr(HPO4)2·H2O (abbreviated as αZrP) and αTi(HPO4)2·H2O (αTiP) were prepared by hydrothermal treatment using the metals in the wastewater.
