DEVICE FOR THE GROWTH OF BIOFILM ON THE INTERIOR SURFACE OF PIPELINES AND THE INFLUENCE OF DISINFECTANTS ON THE BIOFILMS IN FLOWING CIRCULATION SYSTEMS

摘要

The utility model relates to modern instruments for studying biofilms, is intended for microscopic (visual) studies of the life cycle of biofilms formed by various communities of microorganisms on various materials and in different environments under the controlled influence of temperature, lighting, the speed of movement of the liquid medium, and the composition of the gas phase. A device for growing biofilm on the inner surface of pipelines and the effect of disinfectants on biofilms in flowing circulation conditions, including three tanks connected in line and isolated by taps (8, 2, 12) (9, 1, 13) connected to a circulation pump (3) and connected to the pipeline with extension (4) connected to a line including three other reservoirs isolated by taps (5, 14, 10) (6, 15, 11), while four of the reservoirs isolated by taps in pairs (13, 15, 16) connected by pipelines, forming two circuits, n passing through the circulation pump (3) and the pipeline with expansion (4) with the open taps of these tanks and closed with all the other taps, while the tanks (1, 6) contain artificially contaminated aqueous solution, and the tanks (13, 15) contain a disinfectant means, the remaining two tanks (5, 11) are filled with water, while the device is made with the possibility of alternating biofouling of the lumen of the pipelines, processing with a disinfectant and washing off the residues. 1 ill.
