Systems that are susceptible to microbial contamination!

Water and wastewater: Continuous monitoring and control of systems and equipment used in this industry for contamination with sulfate-reducing bacteria and iron bacteria is important for two reasons. One is to maintain the quality of treated water in terms of odor, taste, and color, and the other is to prevent microbiological corrosion and its harmful effects on metal structures used in this industry.

Oil, gas, and petrochemical industries: Continuous monitoring of the equipment and facilities used in refineries and oil and gas industrial wastewater treatment plants for the presence of biofilms formed by microorganisms is of great importance. The aim of this is to maintain the quality of gas and oil produced in this industry and also to protect the facilities used in refineries against the harmful effects of microbiological corrosion. The main microbiological problem of petroleum products is the contamination of stored products, which can lead to a decrease in product quality, the formation of sediment, and corrosion of pipelines and storage tanks, both in the refinery and at the end user. Therefore, controlling and preventing microbial contamination of fuel sources will have an effective role in reducing maintenance and repair costs.

Maritime industry: Microbial contamination in vessels can lead to contamination in fuel, pipelines, cooling water systems, and ballast tanks, which can lead to engine damage (faster wear of pistons and cylinder liners and clogging of filters and injector nozzles sometimes within a few hours), corrosion of fuel tanks, localized corrosion, general corrosive damage to cooling pipes, tank bottoms and hulls. Inside ships, due to the presence of conducive conditions for microbial growth such as water (in pipes) and carbon-based food sources like fuel hydrocarbons and oil, and optimal growth temperature (engine room), it is a suitable place for the growth and attack of fuel and oil degrading microorganisms. Neglecting proper prevention and management methods for contamination and corrosion will lead to equipment failure, equipment corrosion, filter clogging, and overall increase in repair cases.

Steel industry: Microbial corrosion occurs in alloys such as carbon steel, low-alloy steel, aluminum alloys, and copper.

Firefighting: Due to the stagnation of firefighting water, the dissolved oxygen in it decreases and provides a suitable environment for the growth of anaerobic microorganisms, including SRB bacteria, which can cause microbiological corrosion. Corrosion in firefighting water pipes is one of the issues that can lead to the inability to manage fire extinguishing in a timely manner with water, which can cause harm to the lives of employees and impose financial damages. By conducting accurate and regular inspections and taking preventive and control measures, potential damages can be significantly reduced.
