Study of biofilm evolution using a monitoring water system

Simulation of waterfall in nature can be done using a fluid level control system in a pool. This system is made of two mini-pools at a height of 50 cm from each other. The water monitoring system consists of a control and control board that reads the temperature and the flow rate of the water and pumps the water from the lower container to the top. In the pools are introduced different types of substrate (e.g. naval steel, liquid wood) that simulate the resistance of materials in contact with sea water and the evolution of biofouling formation on these materials. The aim of the project is to detect the appearance of biofilm layers on the materials that are integrated into a ship's body, during the time. A comparative analysis is presented in this paper for different type of material and different environmental condition.
