2021-6-3 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.

2008-9-30 Sludge acidification to a pH less than 2.5 with sulfuric acid is another technique that was found to result in significant sludge reduction (WPCF 1989). In Germany, a novel approach to reducing sludge production involved the use of an agitator ball mill to disintegrate bacterial cell walls, thereby releasing an external carbon source for

2010-7-17 The effects of ball mill pretreatment and Mn catalytic ozonation on the reduction of sewage sludge were investigated. The ball mill pretreatment increased ΔSCOD from 2,000mg/L to 9,000 mg/L, as Total Solids (TS) increased from 1% to 4% at a specific energy of 75.8 KJ/g-TSS. The increase in disintegration ratio (DR), which is an index of the solubilization of sewage sludge, was consistent with ...

2020-10-1 The effect of mill scale dosage on the settling behavior of activated sludge is compared with the control experiment (sludge settling in absence of BF) and presented in Fig. 4a. The settling behavior was studied with 0.8, 2 and 4 g dosing rate of mill scale as per 0.4, 1.0 and 2.0 wt ratio of BF to activated sludge.

2021-6-1 Currently, wastewater treatment process sludge, such as granular sludge, is known as a waste product (Lin et al., 2015). The cost of sewage sludge handling/disposal accounts for up to 50% of the cost of wastewater treatment (Kroiss, 2004). The sustainability and economics of wastewater treatment can be significantly improved if biomaterials can ...

2019-2-21 For mechanical treatment of the sludge, a sonicator, a ball mill, and a homogeniser were used to separate the phases of the sludge by applying shear force. The amount of sludge used in the mechanical treatment was 100 g. Sonication was conducted with a rod-type sonicator for 30min. Ball-milling was implemented for 48 h.

As a new sludge reduction technology with a phosphorus removal mechanism, a vibration milling technology that uses iron balls have been applied to the wastewater treatment process. Three anaerobic-aerobic cyclic activated sludge processes: one without sludge disintegration; one disintegrated sludge by ozonation; and the other disintegrated sludge with the vibrating ball mill were compared.

2012-1-1 This is because iron was mixed into the wastewater treatment tank due to abrasion of the iron balls, leading to settling of iron phosphates. Thus, the simple means of using iron balls as the medium in a vibrating ball mill can achieve both a sludge reduction of half and excellent phosphorus removal.
