dc.description.abstractBiofilm adhesion to metals (copper, aluminium and brass) was studied at two different velocities and pH values of 7 and 9. Both bacteria and metals showed negative surface charges at those values of pH, which tends to slow down adhesion. Film densities increased with the fluid velocity and were also affected by the pH and by the growth rate of the bacteria. Long duration tests based on heat transfer measurements were run at five different fluid velocities and at pH = 7, showing in general an asymptotic behaviour and a control of deposition by adhesion and growth phenomena.por

Les charges de surface negatives des mttaux et des bacttries, obtenues pour ces valeurs de pH, tendent & ralentir l’adhesion. La densitt des films augmente avec la vitesse du fluide et est modifik par le pH ainsi que par la vitesse de croissance des bacttries. Des tests de longue durk utilisant des mesures de transfert de chaleur ont ttt effectues pour cinq vitesses de fluide difftrentes h un pH de 7, montrant un comportement asymptotique ainsi qu’un contr6le du dtpat par la croissance et l’adhesion; en outre, la deposition est contr61te par l’adhtsion.por
