    Microbial growth reduction in sewage sludge by stirred

    mill. The grinding chamber of the ball mill was pro-vided with a cooling jacket through which coolant was passed to maintain a temperature of 14 C(±1 C). This is done to take care of the rise in temperature as a result of grinding, which may affect cell rupture to some extent. The mill was operated at 1100rpm with treatment time up to 20min.
