CA 2424711
A method and apparatus for determining the effect of various agents on the growth of biological material (biofilm), microbially-influenced corrosion and the deposition of organic and inorganic contaminants is disclosed. The method and apparatus allow for the modeling of the growth of biological contaminants and the deposition of organic and inorganic materials on industrial equipment surfaces, such as those used in the pulp and papermaking industry. The device consists of a tray which includes recessed areas for receiving coupons, as well as fluid inlets and fluid outlets for permitting the flow of liquid samples over the coupons. The design and configuration of the apparatus provides a great deal of versatility in testing various biocidal and other agents under select environmental conditions.
L'invention concerne un procédé et un appareil qui servent à déterminer l'effet de divers agents sur la croissance d'un matériau biologique (film biologique), la corrosion d'origine microbienne, et le dépôt de contaminants organiques ou inorganiques. Le procédé et l'appareil permettent de modéliser la croissance de contaminants biologiques et le dépôt, sur des surfaces d'un équipement industriel, de matières organiques ou inorganiques, telles que celles utilisées dans l'industrie de fabrication de la pâte à papier ou du papier. Le dispositif est constitué d'un plateau comprenant des zones évidées destinées à recevoir des éprouvettes, ainsi que des orifices d'admission des liquides et des orifices d'évacuation des liquides permettant l'écoulement des échantillons liquides sur les éprouvettes. Le dessin et la configuration de l'appareil offrent une grande diversité des essais sur des agents biocides ou autres, dans des conditions ambiantes choisies.
