Preparing sub-micron macroporous ion exchange materials by mechanical grinding, comprises processing a product slurry having an average particle size of less than 100 mu m in a stirred ball mill or planetary ball mill with process time of 10-180 minutes.

Biogas is a type of biofuels created via anaerobic, or oxygen-free, digestion of organic matter by bacteria. A biogas plant is composed of a digester and a gas holder. The digester is an airtight container in which the waste is dumped and decomposed, and the gas holder is a tank that harnesses the gases emitted by the slurry.

anaerobic digestion. The disintegration techniques used included a stirred ball mill, an ultrasound disintegrator, a lysate centrifuge and ozone treatment. An enhancement of the degree of degradation of 7.4-20% was observed compared to a reference system without pretreatment. Kopplow et al. (2004) investigated the effect of sludge

Table 6 shows results obtained during anaerobic digestion of sludge which had been disintegrated by stirred ball mills. Grinding was more beneficial on digested sludge (increase of batch biogas production by 60%) and on waste activated sludge from an extended aeration process (24% increase) than on activated sludge with an higher SRT (7% ...

In addition, Kopp et al. achieved a increase of SS biodegradation after 2 d and an improvement of approximately 20% after 4 d utilizing the stirred ball mill pretreatment . Milling pretreatment of SS also increases biogas production.

It was suggested to use a continuous stirred tank reactor (CSTR) located between a ball mill and a hollow-fiber cartridge, in order to decrease the energy costs . Another disadvantage of milling is its inability to remove the lignin which restricts the access of the enzymes to cellulose and inhibit cellulases [ 30, 68 ].

The stirred ball mill was applied to the WWTP in 2002. The ball velocity and ball diameter were typically at 6–15 m/s and 0.25–0.35 mm, respectively, while this technology was applied (see Table 2 and Table S8). An increased VS removal of 5% and enhanced biogas production of 10–21% were generally achieved (see Table 2 and Table S8).
