Corrosion, the invisible enemy of WWTPs
Corrosion is the natural process in which metals degrade. This process is influenced by external factors such as humidity, temperature and corrosive gases, mainly active sulfur compounds, sulfide oxides and nitrogen oxides (H2S, SO2, SO3, NOx).
In pumping stations and sewage treatment plants these factors are present, even in very low concentrations (parts per billion), and are the cause of technical and operational failures due to degradation of electrical components.
In order to prevent corrosion-sensitive electrical or electronic equipment from suffering, it is important to take preventive measures.
The solution is to perform a good prior analysis of the environment in corrosion-sensitive areas, install specific air filtration equipment with the appropriate media.
CORROSION COUPONS + BION FILTER MEDIA + SPECIFIC EQUIPMENT = EFFICIENT SOLUTION AGAINST CORROSION
To detect and act reliably against corrosion, BION has an action protocol. The process starts by sending and placing corrosion coupons in the rooms or environments susceptible to corrosion. After 30 days of exposure, the coupons are sent to the laboratory, where an exhaustive analysis of the gases that have been in contact and their concentration is carried out, determining the level of corrosion present in the environment.
Our laboratory is equipped with the necessary technology to investigate and analyze all types of gases derived from the wastewater treatment activity.
BION's team of chemists and engineers determines the best solution for each case. Usually the solution involves the installation of an air filtration equipment with an average according to the results obtained with the coupon.
In this way, carrying out a correct preventive action can fight against the invisible enemy that is corrosion and avoid the appearance of its adverse effects in installations, piping, data centers and vulnerable electronic components among other elements.
