Abstract Granulated micelle-clay composites (0.3 to 2 mm) formed from Na-bentonite and the organic cations Octadecyltrimethylammonium (ODTMA), or Benzyldimethylhexadecylammonium (BDMHDA) were employed to remove from water by filtration ( a ) Escherichia coli S-17 and ( b ) total bacteria count (TBC). In ( a ) filters included 4 g to 27 g of complex mixed with sand, and bacteria numbers were 6.4·10 5 to 5·10 6 /mL. A model which considered convection, adsorption, and desorption simulated the… CONTINUE READING
