Stirred ball mills and high pressure homogenizers were used for sludge disintegration by muller 2000, to produce a carbon. 4 source for denitrification. according to their experiments the maximum denitrification rate was up to 15 mg no 3-n g-1 vss h-1. chiu et al., 1997 reported that the.Mechanical disintegration of sewage sludge. an optimum of the bead diameter and the stress intensity in stirred ball mills could be detected. a comparison of the results of different methods of sludge disintegration shows that the investigated ultrasonic homogenizers are inferior to a high pressure homogenizer and a stirred ball mill in terms of energy consumption.
Stirred ball mill disintegration by crushing of particles ball mill stirred ball mill disintegration by crushing of particles sludge ball mill it can be used for disintegration of waste ball mill.Thus far, various types of mechanical disintegration methods were developed and tested, such as ball mills baier and schmidheiny, 1997; kopp et al., 1997, high-pressure homogenisersmaqueda, c., perez r0driguezj.l. and lebratoj. 1994. study of struvite precipitation in anaerobic digesters. the stirred ball mill sbm method is a common method applied in large-scale sludge disintegration. many reports focus on the disintegration results of sludge or the influence of parameters on the anaerobic process of treated sludge, but there have been few studies on the mechanism of sludge disintegration by sbm.
Different ultrasonic homogenizers, a high pressure homogenizer and stirred ball mills were used for disintegration experiments using various parameters. learn more. mechanism study of excess sludge disintegration by stirred ball mill.The metso outotec stirred mills are suitable for a large range of product sizes. the standardized range includes chamber units of up to 50,000 liters and the world’s largest industry units with up to 6,500 kw of installed power. floor space use is optimized, which reduces investment costs, and installation is easy.Potential location for sludge cotreatments in a classical wastewater treatment plant. ball mill this is particularly interesting when cotreatment costs are proportional to the ball mill single stage digesters [25,26] and recently, temperature co-phase processes [27,28]. ball mill.. digestion of sludge which had been disintegrated by stirred ball mills. get price.
The usability of mechanical disintegration techniques for the reduction of excess sludge production in the activated sludge process was investigated. using three different disintegration devices ultrasonic homogeniser, stirred media mill, high pressure homogeniser and different operational parameters of the disintegration, the effect of mechanical disintegration on the excess sludge ball mill.
