      The coagulants are generally low molecular weight, high charge polymers whereas the flocculants are high molecular weight, low charge polymers. The coagulants are better at charge neutralization of the clays than the flocculants but the flocculants are better for building larger and heavier floes which settle rapidly.

      The use of solid culture media limits the growth of colonies and adherent biofilms. Moreover, it can also confer properties to the cells that are not expressed in liquid media. In addition, some studies have also pointed out that low molecular weight agar-agar-derived polysaccharide materials can be taken at the same time as cells [104,122]. The size of the inoculums may also have an effect on the apparent activity of the antimicrobial agent.

      The process is interesting because low rank/oxidized coals float poorly, and because of the possible utilization of such clean coal products in the form of coal-water slurries. However, to float gangue efficiently the process requires very high dosages of the quaternary amine since adsorption of the amine onto coal is very high.
