sludge can overwhelm this problem; improve degradability of the biological cell material and to liquefL solids as much as possible. Different disintegrating devices, mechanical as stirred ball mills, homogenizers, ultra-sound and other systems can be introduced in sludge treatment technology line
Oct 18, 2020· Jun 03, 2021 Abstract 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.
The 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.
