Abstract
A method for monitoring the formation of biofilm on surfaces which are exposed to a flowpath of liquid essentially containing water includes flowing a liquid along the flowpath only once without being circulated through a tube section, through and along a series of sample tube pieces removably placed within the tube section, successively removing the sample tube pieces without replacement each time after a period of flow elapses and testing the sample pieces removed to determine the biofilm formation thereon. The tube section is arranged essentially vertically, and the flow through the tube section is downwardly directed, the uppermost sample tube pieces being removed in succession after each time period of flow exposure.

Method for monitoring the formation of deposits on surfaces which are exposed to a flowpath of liquid essentially containing water, said method comprising flowing a liquid along a flowpath once only without being circulated through and along a tube section, the flowpath including a series of sample pieces having surfaces for deposit formation thereon removably placed within the tube section and abutted against each other with the geometrical axis of each piece oriented along the liquid flowpath, successively removing without replacement said sample pieces each time after another time period of flow exposure elapses and testing said sample pieces removed to determine the existence, thickness, type or composition of deposit formation thereon.
Apparatus for monitoring the formation of deposit, such as biofilm, on surfaces which are exposed to a flowpath of liquid containing essentially water, said apparatus comprising a tube system provided with an inlet and an outlet for conducting the liquid, the tube system comprising a flowpath of at least one tube section with a series of sample pieces inserted inside, arranged in abutment against each other and each sample piece having its geometrical axis oriented along the liquid flowpath within said tube section and means for affording access to the tube section in order to remove and/or position any of the sample pieces disposed within said tube section.
